Christianity in Sudan

Christianity in Sudan begins not with European missionaries or the modern civil wars for which the country is often known, but with one of the great indigenous Christian civilizations of medieval Africa. For centuries, Christian kingdoms governed much of the Nile Valley within the territory of modern Sudan. Their rulers built churches and monasteries, bishops administered dioceses, scribes wrote in Greek, Coptic and Old Nubian, artists covered cathedral walls with images of Christ, the Virgin Mary, saints, bishops and kings, and Christian institutions stood near the centre of political and cultural life. The ruins of Old Dongola, Soba, Ghazali and Banganarti are therefore not traces of a temporary foreign mission. They are the remains of African societies in which Christianity became deeply rooted and, for long periods, politically dominant.

Christianity became firmly established in Nubia during the sixth century, when Nobadia in the north, Makuria farther south and Alodia toward the region of modern Khartoum adopted the Christian faith. These kingdoms were connected to the wider Christian world of Egypt and the eastern Mediterranean, but they were not simply extensions of Byzantine or Egyptian power. Christianity was absorbed into indigenous systems of kingship, language, art and social organization. Nobadia was eventually incorporated into Makuria, whose capital at Old Dongola developed into a major centre of medieval Nubian civilization, while Alodia ruled from Soba much farther south. Monasteries flourished, pilgrimage centres attracted ordinary believers, and a distinctive Nubian Christian culture emerged whose surviving art combines local, Coptic and Byzantine influences without being reducible to any of them.

This Christian political world faced a profound challenge after Arab-Muslim armies conquered Egypt in the seventh century. The conquest of Egypt placed a rapidly expanding Islamic state immediately north of Christian Nubia, and Muslim forces attempted to continue southward. Nubian resistance, however, was formidable. Makurian archers acquired a fearsome reputation, and the Arab-Muslim armies failed to absorb the kingdom as they had Egypt. Warfare was followed by the arrangement traditionally known as the Baqt, which regulated relations between Muslim-ruled Egypt and Christian Nubia and helped preserve Makuria's independence for centuries.

The Baqt is rightly remembered as evidence that the early Islamic conquests did not simply sweep through Sudan. Christian Nubia successfully resisted incorporation into the caliphate, retained its kings, bishops and churches, and continued to produce a rich Christian culture long after Egypt had come under Muslim rule. Yet the arrangement should not be romanticized as a modern treaty of peaceful equality. Traditions concerning the Baqt include recurring obligations involving goods and enslaved people sent northward from Nubia, with goods supplied from Egypt in return. Its historical meaning is therefore complicated: it protected the sovereignty of a Christian African state while operating within a medieval political economy in which human beings could themselves become part of interstate obligation and exchange.

For several centuries this frontier arrangement allowed Christian Nubia to flourish. Old Dongola became monumental, monasteries and churches multiplied, and religious art and writing reveal a society confident enough to develop its own Christian visual and literary traditions. At Faras, later submerged beneath the waters created by the Aswan High Dam, archaeologists recovered extraordinary cathedral paintings before the site disappeared. At Banganarti, inscriptions left by pilgrims show that Christian devotion was not confined to rulers and clergy. Ghazali demonstrates the reach of monasticism, while Soba shows that Christian political culture extended deep into central Sudan. Christianity in medieval Sudan was not merely surviving; it was creating a civilization.

That civilization did not disappear in a single conquest or through a single mass conversion. Its decline unfolded across centuries, and the causes included migration, intermarriage, economic change, political fragmentation and voluntary conversion as well as military pressure and the loss of Christian political power. Arab-speaking populations increasingly entered Nubian territories, Islamic institutions became more influential, and local social networks changed. But describing the process only as gradual cultural evolution leaves out the increasingly violent political pressure that helped destroy the states capable of sustaining Christianity as a public order.

From the late thirteenth century, Mamluk Egypt repeatedly intervened in Makuria. These were not merely diplomatic disputes. Armed expeditions penetrated Nubian territory, rival claimants to the throne were supported or removed, tribute and submission were imposed, and rulers acceptable to Cairo could be installed through outside military power. Makuria had preserved its sovereignty for centuries after resisting the first Arab-Muslim invasions, but repeated Mamluk intervention progressively weakened that independence. Internal dynastic struggles mattered as well, yet those internal divisions made the kingdom increasingly vulnerable to a powerful Muslim state to the north that was prepared to use military force to determine who ruled Christian Nubia.

The transformation became dramatically visible at Old Dongola in 1317. Following renewed Mamluk intervention in Makurian succession, the Muslim ruler Abdallah Barshambu was installed, and the monumental royal Throne Hall associated with Christian kingship was converted into a mosque. This did not mean that every Nubian became Muslim in 1317, nor did Christianity immediately disappear from the Nile Valley. Christian communities survived for generations in some places. The conversion of the royal building nevertheless symbolized something far larger than an architectural alteration: the political centre of a kingdom that had resisted Islamic conquest for centuries was no longer securely under Christian rule.

As Makuria weakened, the institutional framework supporting Nubian Christianity weakened with it. Churches could survive after kings lost power, families could retain Christian identity after political institutions changed, and conversion proceeded at different speeds from one locality to another. Yet a religion that had once been supported by kings, bishops, monasteries, landholding institutions and a Christian court increasingly existed within a political and social environment dominated by Muslim rulers and expanding Islamic institutions. The disappearance of Christian sovereignty did not automatically convert the population, but it changed the conditions under which Christianity could reproduce itself from generation to generation.

Farther south, Alodia survived longer. From Soba, near modern Khartoum, its rulers maintained the last major Christian state in the territory of modern Sudan. Medieval descriptions and archaeological remains point to a substantial urban centre with churches and other important buildings, demonstrating again that Sudanese Christianity had never been confined to a narrow frontier adjoining Egypt. Yet Alodia too fragmented as regional political, demographic and economic conditions changed. Arab tribal expansion and the rise of new Muslim powers altered central Sudan, and by the opening of the sixteenth century the Christian political order centred on Soba had collapsed. Tradition associates this transformation with the emergence of the Funj Sultanate around 1504.

The evidence for the precise circumstances of Soba's fall is too incomplete to justify inventing a massacre, a Christian death toll or a single decisive battle for which the sources cannot account. What can be said is consequential enough: the last major state capable of maintaining Christianity as the religion of political authority in Sudan disappeared. By the early modern period, the great medieval Christian kingdoms were gone, and Islam increasingly shaped the political and cultural order of the Nile Valley. The process had involved peaceful interaction and conversion, but it had also involved warfare, outside intervention, political subordination and the destruction of the sovereignty on which the medieval churches had depended.

Christianity nevertheless never became entirely foreign to Sudan. Coptic connections continued across the Egyptian-Sudanese frontier, and during the nineteenth century Coptic Christians from Egypt became increasingly visible as merchants, craftsmen, administrators and professionals. Khartoum acquired an established Coptic community, reconnecting modern Sudan with the older Christian world of the Nile. Catholic missionary activity also expanded, followed by Protestant and Anglican missions. Churches, schools and medical institutions appeared, although missionary activity remained uneven and politically sensitive.

This renewed Christian presence was violently disrupted by the Mahdist revolution. Beginning in the 1880s, the Mahdist movement overthrew Turco-Egyptian authority through an extraordinarily destructive war and established an explicitly Islamic revolutionary state. As Mahdist forces captured towns and extended their control, Christian mission stations were overrun and the small missionary network that had re-emerged in Sudan was shattered. Clergy, missionaries and other Christian personnel were killed, captured, expelled or forced to flee, while mission property was seized, abandoned or destroyed. Christians held under Mahdist authority could also face coercive pressure to conform to the new religious order.

The Mahdist period requires the same precision demanded elsewhere in Sudan's history. The wars were catastrophically violent, but their enormous mortality cannot simply be counted as Christian persecution. Muslims who opposed Mahdist claims suffered terribly as well, and political resistance, warfare, famine and disease devastated populations irrespective of Christian identity. At the same time, acknowledging the wider catastrophe must not erase what happened specifically to Christian institutions and captives. An Islamic revolutionary state had replaced the previous regime, organized Christian mission life was suppressed, and Christians caught within its expanding power could lose their freedom, institutions and ability to practise their religion independently.

The defeat of the Mahdist state at the end of the nineteenth century opened another period of Christian expansion under Anglo-Egyptian rule. Catholic, Anglican and Protestant missions established schools, churches and medical institutions, while Coptic Christians continued to form an important community in northern cities. Colonial authorities, however, increasingly treated northern and southern Sudan as culturally distinct spaces. The predominantly Muslim and Arabic-speaking north was largely protected from intensive Christian missionary activity, while missions were given considerably more room in the south, where populations followed diverse indigenous religions and Christianity was expanding.

This policy did not create Sudan's north-south differences from nothing, but it reinforced them. Mission schools became important institutions in southern communities, Christianity spread among several peoples, and southern educational and political development increasingly followed a different path from that of the north. Colonial administrators failed to construct a political settlement capable of reconciling these profound regional differences before independence. As British and Egyptian rule drew to an end, many southerners feared that the departure of foreign rulers would simply transfer power to northern elites concentrated in Khartoum.

Sudan became independent in 1956, but fighting in the south had already begun. The First Sudanese Civil War was never simply a Christian rebellion against a Muslim government. Southern grievances included political exclusion, regional inequality, language, employment, cultural autonomy and fear of domination by northern institutions. Religion nevertheless became increasingly entangled with those disputes because many southern communities were Christian or followed indigenous religions while governments in Khartoum increasingly associated Sudanese national identity with Arabic language and Islam.

Christian institutions consequently became politically vulnerable. In 1964 the government expelled large numbers of foreign Christian missionaries from the south. Churches, schools and clinics suddenly lost clergy, teachers, medical workers and administrators. Christianity itself did not disappear; local clergy and lay communities increasingly assumed responsibilities previously held by foreigners. Yet the expulsions demonstrated that the state could treat Christian institutions as politically suspect and remove the people upon whom those institutions had depended.

The Addis Ababa Agreement of 1972 ended the first civil war and granted the south substantial regional autonomy. For roughly a decade, southern communities experienced relative peace, and Christian institutions had space to rebuild. That settlement eventually unravelled as President Jaafar Nimeiri centralized power, altered southern administrative arrangements and moved toward a more explicitly Islamic political program. In 1983 his government introduced the September Laws, extending an Islamized legal framework nationally. For Christians and other non-Muslims in the south, the issue was larger than individual criminal provisions. The laws reinforced the fear that the Sudanese state was defining citizenship through a religious identity that did not include them on equal terms.

At almost the same moment, disputes over southern autonomy, military power and resources reignited war. The Second Sudanese Civil War became one of the most destructive conflicts in modern African history. The Sudan People's Liberation Movement drew much of its strength from the south but increasingly presented a political vision of a restructured Sudan rather than a straightforward Christian crusade against Islam. The war nevertheless acquired a powerful religious dimension because governments in Khartoum promoted Islamic law and Arab-Islamic national identity while many populations resisting government power were Christian or followers of indigenous religions.

For civilians, the consequences were catastrophic. Villages were attacked, crops and livestock destroyed or stolen, populations displaced and entire regions exposed to famine and disease. Millions were uprooted. Families fled toward Khartoum, crossed into Uganda, Kenya and Ethiopia or entered refugee camps where churches became important centres of relief, education and community reconstruction. A modern Sudanese Christian diaspora grew out of this violence, but the word migration alone is inadequate to describe what happened. Many people did not leave because they had calmly chosen a new home; they fled because the political and physical conditions required for life had been destroyed around them.

Among the darkest features of the war was the abduction and enslavement of civilians. Government-backed or government-aligned murahileen militias raided southern communities, particularly in Bahr el Ghazal. Women and children were seized during attacks and carried away from their homes. Documented victims were held in slavery or slavery-like conditions, compelled to perform unpaid domestic or agricultural labour, beaten for resistance, separated from their families and, in some cases, sexually abused or sold. Some captives also experienced pressure to assume Muslim names, identities or religious practices.

Many victims came from Dinka and other southern communities in which Christianity and indigenous religions were prominent. The pattern therefore forms an indispensable part of the history of Sudanese Christians, but it must be described accurately. The raiding system combined ethnicity, race, regional origin, counterinsurgency and religion; it was not a mechanism that selected every victim solely because he or she was Christian. That qualification does not soften the atrocity. Women and children were violently taken from their families and deprived of control over their labour, movement and bodies. Where investigators documented slavery, forced labour, beatings and sexual abuse, those terms belong in the history.

The Nuba Mountains reveal the same intersection of religious persecution with a much wider campaign of state violence. The Nuba population is religiously diverse, including Muslims, Christians and followers of indigenous traditions. During the Second Civil War, parts of the region supported the SPLM, bringing communities into conflict with the government. The counterinsurgency of the 1990s was devastating. Civilians were killed, villages and property were destroyed, populations were forcibly displaced or concentrated in government-controlled areas, detainees suffered abuse, and humanitarian access was severely restricted.

For Christian Nuba, this violence unfolded alongside government policies promoting Islamization and Arabization. Churches and Christian communities could be treated not only as religious institutions but as markers of populations suspected of political disloyalty. Yet Muslim Nuba and adherents of indigenous religions suffered under the same counterinsurgency. The brutality should therefore neither be stripped of its religious dimension nor falsely transformed into a war in which every perpetrator was attacking every victim because of Christianity. Sudan repeatedly demonstrates how religious identity could intensify vulnerability inside conflicts simultaneously driven by ethnicity, political allegiance, territory and state control.

The ideological environment became still harsher after Omar al-Bashir seized power in 1989 with the support of the National Islamic Front. The new regime intensified efforts to define Sudan as an Arab-Islamic state. Islamic law, education, security institutions and public culture became instruments of that project. Christians were not continuously subjected to physical attack everywhere, and churches remained visible in Khartoum and other cities, but they lived within a state whose formal ideology privileged Islam and whose security apparatus could interpret Christian identity through the lenses of southern ethnicity, foreign influence or political disloyalty.

Church construction and property rights became difficult, Christian organizations encountered administrative interference, and converts from Islam faced particularly grave danger under apostasy legislation. Churches serving displaced populations around Khartoum could be demolished or lose land. Missionary activity was restricted, foreign Christian workers could be expelled, and security agencies monitored both religious and political activity. For displaced southern Christians who had built congregations on the outskirts of the capital, a church might be simultaneously a place of worship, a school, a relief centre and one of the few institutions holding together a community uprooted by war. Its destruction therefore carried consequences far beyond the loss of a building.

The civil war eventually ended through the Comprehensive Peace Agreement of 2005, which established power-sharing arrangements and a process through which southern Sudan would determine its future. The agreement brought desperately needed relief after decades of war and allowed separated families and damaged institutions to begin rebuilding. Yet it also forced Sudan to confront the constitutional question that successive governments had failed to resolve: whether its radically different regional, ethnic and religious communities could share a common political state after so much bloodshed.

In the 2011 referendum, southern Sudan voted overwhelmingly for independence, and South Sudan became sovereign on 9 July. For the Christian population graph, this moment must be interpreted with unusual care. Before 2011, statistics for Sudan included the people living in what became South Sudan, where Christianity had become deeply established. After independence, those same people were no longer counted within Sudan. They had not suddenly converted, emigrated or been killed. The international border changed, and with it the territorial meaning of the word Sudan.

This distinction is essential because a graph that directly compares unified Sudan with the post-2011 Republic of Sudan can create the illusion of an enormous instantaneous religious collapse. Genuine Christian migration and displacement occurred as well. People of southern origin left Khartoum for the new state, others moved to Egypt or East Africa, and many joined communities farther abroad. But much of the statistical decline was caused by partition itself. Millions of Christians disappeared from Sudan's demographic denominator without disappearing as people.

Partition also left Christians who remained north of the new border in a more precarious position. Coptic communities remained in Khartoum and other cities, while Christians continued to live in the Nuba Mountains, Blue Nile and elsewhere. Catholic, Protestant and Orthodox congregations still formed part of Sudanese society. Yet the departure of the overwhelmingly non-Muslim south strengthened the Bashir government's argument that the remaining country could be defined even more explicitly in Arab and Islamic terms. Christians now constituted a smaller minority with less political weight, while people of southern origin who had lived for years or generations in northern Sudan faced difficult questions of citizenship and legal status.

War also resumed almost immediately in regions that remained inside Sudan. Fighting erupted in Southern Kordofan, including the Nuba Mountains, in 2011 and spread to Blue Nile. Communities that had fought alongside the SPLM during the previous civil war now found themselves politically separated from South Sudan while their disputes with Khartoum remained unresolved. Civilians again experienced bombardment, displacement, food insecurity and restrictions on humanitarian assistance. Christians were among those driven from their homes, and Nuba Christian communities that had survived the 1990s entered another cycle of war scarcely as the larger north-south conflict was supposed to have ended.

Pressure on churches continued after partition. Christian communities faced disputes over registration, land and permission to construct or maintain buildings, and some churches were demolished by authorities who argued that the departure of southerners had reduced the need for Christian places of worship. That reasoning exposed a deeper problem: Christianity could be treated as if it belonged primarily to people who were now presumed to belong in another country, despite Sudan's own Christian history reaching back more than a millennium before the creation of South Sudan.

The danger faced by converts from Islam became internationally visible in 2014 through the prosecution of Meriam Ibrahim. A Sudanese court treated her as Muslim despite her Christian identity, sentenced her to death for apostasy and convicted her of adultery because the state did not recognize her Christian marriage as valid. The sentence was eventually overturned and she left Sudan, but the case demonstrated how an ostensibly abstract law defining religious identity could reach directly into marriage, family status, personal liberty and the possibility of execution.

The Bashir system finally began to break under mass protests in 2018 and 2019. Christians joined Muslim Sudanese in a broad movement against authoritarian rule, economic collapse and the political order constructed over three decades. Bashir fell in April 2019, and the transitional period that followed produced some of the most important religious reforms in modern Sudan. The apostasy law was abolished, parts of the explicitly Islamist legal structure were dismantled, and the government moved toward a conception of citizenship less dependent upon religious identity.

For Christians who had spent decades living under a state that formally privileged Islam, these reforms were substantial. They also showed that Sudanese political history was not predetermined to repeat the Bashir era forever. Muslim and Christian citizens could participate together in demands for a less authoritarian and more pluralistic state. Yet legal reform required stable institutions, and Sudan's transition did not receive enough time to establish them securely. A military coup in October 2021 derailed the movement toward civilian government, and tensions between the Sudanese Armed Forces and the Rapid Support Forces eventually exploded into open war in April 2023.

The present war has produced another national catastrophe. Khartoum, Omdurman and Bahri became battlefields, residential districts were shelled and occupied, hospitals and infrastructure collapsed, and millions of civilians were displaced. Churches have been damaged, occupied, looted or rendered inaccessible, and Christian clergy and congregations have scattered alongside the rest of the population. Christians have suffered rape, displacement, hunger, loss of property and the destruction of community institutions within a war characterized by extreme abuses against civilians.

Yet the current conflict must not be rewritten as a Muslim war against Christians. Both principal armed forces emerge from a predominantly Muslim society, and the overwhelming majority of Sudanese victims are themselves Muslim. Atrocities including rape, sexual slavery, ethnic killing and forced displacement must be attributed to the responsible armed actors and the populations actually targeted rather than automatically classified as anti-Christian persecution. For Christian communities, the particular danger lies partly in their demographic fragility. A small congregation that loses its church, clergy and half its families may find rebuilding much more difficult than a majority population with thousands of institutions.

The war has therefore created another layer of Christian displacement even where religion is not the principal motive for violence. Sudanese Christians have fled to Egypt, South Sudan, Chad, Ethiopia, the Central African Republic and countries farther abroad. Some families are experiencing displacement for the second or third time. A person driven from southern Sudan to Khartoum during the Second Civil War could have lived through partition, remained in the Republic of Sudan and then been forced from Khartoum again in 2023. A Nuba Christian family could have survived the counterinsurgency of the 1990s, renewed fighting after 2011 and the destabilization of the present war.

Such histories explain why Sudan's Christian population cannot be understood through percentages alone. In the medieval period, no census can tell us precisely what share of the population was Christian, although Christianity clearly dominated substantial areas governed by Nubian Christian states. The later decline cannot responsibly be represented as a perfectly smooth numerical curve because Islamization occurred unevenly over centuries. In the modern period, the statistical problem is different: pre-2011 Sudan and post-2011 Sudan are not geographically the same country. A graph therefore has to carry historical explanation alongside its numbers or it risks converting political partition into an imaginary episode of mass religious disappearance.

The Christian diaspora presents a similar challenge. Many people who entered Kenya, Uganda, Canada, the United States, Australia or Europe as Sudanese Christian refugees before 2011 were born in territory that is now South Sudan. Treating all of them as a diaspora from the present Republic of Sudan would distort their history. Other communities clearly belong to the continuing Sudanese story: Coptic families from Khartoum, Christians from the Nuba Mountains and Blue Nile, and refugees escaping the war that began in 2023. Churches abroad preserve languages, family networks and religious traditions, assist new arrivals and maintain ties with congregations inside Sudan. Their growth can therefore represent both Christian resilience and the destruction that made life at home impossible.

Sudan's physical Christian heritage provides an equally important corrective to the idea that Christianity is merely a modern or foreign presence. Old Dongola preserves the remains of the capital of Christian Makuria, where churches, monasteries and monumental buildings once stood within a society governed by Christian kings. Banganarti preserves evidence of pilgrimage and popular devotion, Ghazali reveals a rich monastic culture, and Soba marks the centre of Christian Alodia farther south. The paintings rescued from Faras before the cathedral disappeared beneath the waters of the Aswan High Dam preserve the faces of bishops, rulers, saints and biblical figures from a civilization whose physical landscape has partly vanished.

Modern churches add another layer to that heritage. Coptic congregations maintain connections extending along the Nile into Egypt, while Catholic and Protestant institutions record both the missionary period and the emergence of locally led African churches. In the Nuba Mountains, Christianity is not an archaeological memory but a living religious tradition whose communities have endured repeated war. Sudan therefore contains the remains of Christian states that disappeared centuries ago alongside congregations still struggling to preserve their people, buildings and institutions today.

The long history of Christianity in Sudan is consequently neither a simple story of peaceful demographic evolution nor a single continuous campaign of religious extermination. Christianity began as the faith of powerful indigenous African kingdoms. Those kingdoms resisted early Arab-Muslim conquest with remarkable success, but over centuries their sovereignty was eroded through internal fragmentation, migration, conversion and increasingly forceful intervention from Muslim powers to the north. Mamluk invasions helped break Makurian independence, the royal centre at Dongola passed into Muslim control, and the eventual collapse of Alodia removed the last great Christian state in Sudan.

Christian institutions later reappeared through Coptic settlement and missionary activity, only to be shattered again during the Mahdist revolution. Under colonial rule Christianity grew strongly in southern regions, becoming intertwined with political struggles over the nature of the Sudanese state. Independence brought civil war, missionary expulsions and increasingly explicit attempts by governments in Khartoum to identify the nation with Arab culture and Islam. The Second Civil War then brought devastation on an enormous scale: villages destroyed, millions displaced, women and children abducted, people held in slavery or slavery-like conditions, and communities in places such as the Nuba Mountains subjected to brutal counterinsurgency alongside Islamization pressure.

Under Bashir, those wartime realities existed beside a legal and administrative system that explicitly privileged Islam. Churches faced restrictions and demolition, Christian organizations encountered state interference, and apostasy law placed converts in extraordinary danger. Partition in 2011 then transformed the demographic map without physically removing millions of Christians: most of the territory where modern Sudanese Christianity had become strongest simply became another country. Christians remaining in Sudan faced renewed questions about citizenship, property and whether they fully belonged within a state increasingly described in Islamic terms.

The post-Bashir reforms briefly offered a different possibility. Abolition of the apostasy law and movement toward more equal citizenship demonstrated that Sudan could alter the relationship between religion and political power. That opening was interrupted by military rule and then by a war whose devastation now threatens every Sudanese community. Christianity is not the central target of that war, but Christian institutions are again being scattered and destroyed within it.

Across this history, political power repeatedly determined whether Christian communities possessed the institutions required to endure. Medieval Christianity flourished when Christian Nubian states protected bishops, monasteries and churches. It contracted as those states lost sovereignty. Missionary Christianity expanded when nineteenth- and twentieth-century political conditions allowed institutions to be built and was suppressed when the Mahdist state or later governments regarded those institutions as incompatible with their political and religious programs. Southern churches grew amid communities that later became central to struggles over Sudanese identity, and displaced Christians rebuilt congregations in Khartoum only to find those communities vulnerable to demolition, citizenship disputes and another devastating war.

The population graph may therefore show decline, but the line cannot explain what the decline means. At one point it reflects the disappearance of medieval Christian states and centuries of Islamization. At another it reflects civil war and forced migration. In 2011 it reflects the creation of an international border. After 2023 it reflects another wave of people fleeing a collapsing state. Behind those changes are experiences that cannot be reduced to numbers: rulers losing kingdoms, captives crossing frontiers, missionaries imprisoned, children abducted from villages, women subjected to slavery and sexual abuse, churches demolished, families crossing borders and congregations rebuilding in refugee settlements and foreign cities.

Christianity in Sudan has existed as a civilization, a ruling faith, a minority tradition, a missionary church, a politically suspect identity, a displaced community and a global diaspora. Its history contains coexistence and cultural exchange, but also conquest, coercion, slavery, religious discrimination and war. Preserving all of those realities is essential. To describe the disappearance of medieval Christian Sudan merely as gradual conversion would conceal the military and political destruction that accompanied the loss of Christian sovereignty; to describe every later Sudanese conflict merely as Muslims persecuting Christians would conceal the ethnic, regional and political forces that also drove the violence.

What remains is a history of extraordinary endurance through repeated transformations. The Christian kingdoms of Nubia are gone, but their churches, inscriptions and paintings remain. The old Christian political order disappeared, but Christianity returned in other forms. Civil wars uprooted millions, yet displaced believers built new congregations. Governments attempted to define Sudan in ways that marginalized Christians, yet Christians remained part of the country and participated alongside Muslims in movements for political change. Even now, amid another catastrophic war, Sudanese Christian communities continue both inside the country and throughout a widening diaspora.

Christianity is therefore not an incidental footnote to Sudanese history. It is one of the traditions through which the history of the Nile Valley, the rise and fall of African kingdoms, the expansion of Islam, slavery and captivity, colonial rule, civil war, state Islamization, partition and modern displacement can be understood. The ruins at Old Dongola and Soba, the churches of Khartoum, the congregations of the Nuba Mountains and the Sudanese churches now scattered abroad belong to different centuries and different political worlds, but together they form one long historical record: a Christian presence repeatedly transformed by conquest, state power and displacement, repeatedly reduced or scattered, and repeatedly rebuilt.
