Lands of the Cross: A Deep Dive into the Countries That Were Christian Before Islam

A World Steeped in Faith: The Christian Landscape Before the 7th Century

To truly grasp the monumental shifts of the 7th century, it’s essential to first understand the world as it was. When we ask, which countries were Christian before Islam, the answer reveals a landscape profoundly different from our modern map. The heartlands of what we now call the Middle East and North Africa were not just peripherally Christian; they were, in many cases, the very epicenters of Christian thought, culture, and political power. In short, a vast and diverse tapestry of Christian kingdoms and empires dominated the region, from the shores of the Atlantic to the plateaus of Persia and the deserts of Arabia. This article delves into the rich history of these Christian lands, exploring their unique faiths, their powerful kingdoms, and the world they inhabited just before the dawn of Islam.

Before the Islamic expansions began in the 630s AD, Christianity was the dominant religion of the Roman/Byzantine Empire, which controlled much of the Mediterranean basin. Furthermore, independent Christian kingdoms flourished in Armenia, Georgia, Ethiopia (Aksum), and Nubia (modern Sudan). Even within the officially Zoroastrian Sasanian Empire (Persia) and across the Arabian Peninsula, vibrant and influential Christian communities, including powerful Arab Christian kingdoms, had been established for centuries. This was a world where the primary geopolitical and religious rivalry was between Christian Byzantium and Zoroastrian Persia, and where Christian theology was debated with fervent passion in cities like Alexandria, Antioch, and Constantinople.

The Colossus of Christendom: The Byzantine Empire

When thinking of Christian states before Islam, the Eastern Roman Empire, more commonly known as the Byzantine Empire, immediately comes to mind. It was, without a doubt, the most powerful and influential Christian state in the world. Its official religion was Christianity, established since the Edict of Thessalonica in 380 AD, and its emperor was considered God’s vice-regent on Earth. The empire’s territories encompassed a vast array of historically significant Christian lands.

Anatolia (Modern Turkey)

Anatolia was the heartland of the Byzantine Empire and was thoroughly Christianized. This is the land where St. Paul conducted many of his missionary journeys and where the Seven Churches of Asia, mentioned in the Book of Revelation, were located. Great centers of theological learning and ecclesiastical power, such as Nicaea and Chalcedon, were situated here. It was here that the foundational ecumenical councils took place, shaping the core tenets of Christian doctrine for centuries to come. The population was overwhelmingly Christian, adhering mainly to the Chalcedonian (or Orthodox) faith defined by the Council of Chalcedon in 451 AD.

The Levant (Syria, Palestine, Lebanon, Jordan)

This region was, of course, the birthplace of Christianity itself. By the 7th century, cities like Jerusalem, Antioch, and Damascus were venerable centers of Christian faith. Jerusalem was a major pilgrimage site, home to the Church of the Holy Sepulchre. Antioch was one of the original patriarchates of the Church, where the followers of Jesus were first called “Christians.”

However, the Levant was also a region of significant theological diversity and dissent. While the imperial-backed faith was Chalcedonian Orthodoxy, a very large portion of the local Semitic-speaking population (Aramaic/Syriac speakers) adhered to Miaphysitism. They believed in a unified nature of Christ and had rejected the Council of Chalcedon. This led to the formation of the Syriac Orthodox Church. This theological divide between the Greek-speaking Chalcedonian elites and the Syriac-speaking Miaphysite populace was a significant internal fault line within the Byzantine province of Syria.

Egypt

Was Egypt Christian before Islam? Absolutely. In fact, Egypt was one of the wealthiest and most significant provinces of the Byzantine Empire and a powerhouse of Christian thought. The city of Alexandria was a rival to both Rome and Constantinople in ecclesiastical prestige and theological scholarship. It was the home of the Catechetical School of Alexandria and great Christian thinkers like Clement, Origen, and Athanasius.

Like Syria, Egypt was also a hotbed of non-Chalcedonian Christianity. The vast majority of the native Egyptian population belonged to what would become the Coptic Orthodox Church, which also held a Miaphysite Christology. The Copts had their own Pope of Alexandria and a rich Christian tradition expressed in the Coptic language. This religious friction with the Chalcedonian rulers in Constantinople often translated into political tension, a factor that would play a role during the subsequent Arab conquest.

North Africa (The Maghreb)

The Roman provinces of Africa Proconsularis (modern Tunisia), Numidia (eastern Algeria), and Mauretania (western Algeria and northern Morocco) had a storied Christian history. This was the land of towering figures of Latin Christianity like Tertullian, Cyprian of Carthage, and, most famously, Augustine of Hippo. The city of Carthage was a major center of the Latin-speaking church. While its vibrancy was diminished by the Vandal conquest and subsequent Byzantine reconquest, North Africa remained a predominantly Christian region in the early 7th century, albeit with its own internal schisms like Donatism, which had challenged the authority of the mainstream Church for centuries.

The First Christian Nations: Armenia and Georgia

While the Roman Empire adopted Christianity as a state religion in 380 AD, it was not the first nation to do so. That distinct honor belongs to its neighbor to the east.

A Point of Pride: The claim to be the “first Christian nation” is a cornerstone of Armenian national identity and a verifiable historical fact.

The Kingdom of Armenia

In a move that predated the Roman Empire’s official adoption by nearly eight decades, the Kingdom of Armenia became the first country to declare Christianity as its state religion in 301 AD. This historic conversion was led by St. Gregory the Illuminator, who successfully converted King Tiridates III. This event established the Armenian Apostolic Church, one of the most ancient Christian communities in the world.

Geographically caught between the rival Byzantine and Persian empires, Armenia’s distinct Christian identity became a crucial element of its national survival. The Armenian Church did not attend the Council of Chalcedon and thus developed its own independent theological path, part of the Oriental Orthodox communion alongside the Coptic and Syriac churches.

The Kingdom of Georgia (Iberia)

Following closely behind its southern neighbor, the Georgian Kingdom of Iberia (in the east of modern Georgia) adopted Christianity around 337 AD. The conversion is traditionally attributed to the missionary work of a woman, St. Nino of Cappadocia. King Mirian III, after a miraculous event during a hunting trip, declared Christianity the state religion. The Georgian Orthodox Church initially operated under the authority of the Church of Antioch but later became autocephalous (self-governing), and unlike Armenia, it eventually accepted the doctrines of the Council of Chalcedon, aligning it with the Byzantine Orthodox world.

Christianity in the Persian Sphere and Arabia

It’s a common misconception that the world east of Byzantium was devoid of Christianity. In reality, a unique and resilient form of Christianity thrived within the Sasanian Persian Empire and across the Arabian Peninsula.

The Church of the East in the Sasanian Empire

The Sasanian Empire, with its state religion of Zoroastrianism, was the great rival of Byzantium. Within this empire, however, a large and well-organized Christian community existed: the Church of the East. Often pejoratively labeled “Nestorians” by their Western rivals due to their Christological stance (which emphasized a sharper distinction between Christ’s human and divine natures), this church was centered in the Sasanian capital of Seleucia-Ctesiphon (in modern Iraq).

Because they were theologically distinct from the Byzantine state church, the Persian shahs sometimes tolerated them as a counterweight to Roman influence. At other times, however, they faced brutal persecution. Despite this, the Church of the East was remarkably vibrant and missionary-focused, spreading Christianity along the Silk Road into India, Central Asia, and even China long before Western missionaries arrived.

The Christian Kingdoms of Arabia

Was Arabia Christian before Islam? In many parts, yes. The Arabian Peninsula in the 6th and 7th centuries was not a monolithic pagan landscape. It was a patchwork of tribes and kingdoms with diverse religious beliefs, including well-established Christian communities.

• The Ghassanids: This powerful confederation of Arab tribes ruled over a client kingdom in parts of modern-day Syria, Jordan, and northern Saudi Arabia. They were staunch allies of the Byzantine Empire and were devout Miaphysite Christians. Their courts were centers of Arabic Christian culture and poetry, and they served as a buffer state protecting Byzantium’s eastern frontier from both the Persians and other desert tribes.
• The Lakhmids: As rivals to the Ghassanids, the Lakhmids were a client kingdom of the Sasanian Persian Empire, centered at al-Hirah (in modern Iraq). For much of their history, their rulers were pagan, but their population included a very large and influential contingent of Church of the East Christians. In fact, the last Lakhmid king, al-Nu’man III, converted to Christianity around 594 AD.
• Christians in Yemen and Najran: Southern Arabia, particularly the city of Najran (in modern Saudi Arabia, near the Yemeni border), was a major center of Christianity with a well-established bishopric. The community of Najran became famous for a brutal persecution it suffered in the 6th century at the hands of the Himyarite king Dhu Nuwas, who had converted to Judaism. This event sent shockwaves across Arabia and is even referenced in the Quran.

Christianity in Africa: Beyond Egypt

The Christian faith had put down deep roots in Africa well south of Egypt long before the 7th century.

The Kingdom of Aksum (Ethiopia and Eritrea)

The powerful Kingdom of Aksum, a major trading empire controlling the Red Sea routes, adopted Christianity as its state religion around 330 AD under King Ezana. The conversion was initiated by Frumentius, a Syrian Greek who was shipwrecked and brought to the Aksumite court. He later traveled to Alexandria and was consecrated as the first bishop for Ethiopia, establishing a lineage that connected the Ethiopian Church to the See of Alexandria for over 1,600 years.

The Ethiopian Orthodox Tewahedo Church, like the Coptic Church, is part of the Oriental Orthodox communion. Aksum’s Christian identity was so strong that it famously gave refuge to the early followers of the Prophet Muhammad when they fled persecution in Mecca, a historical event cherished in Islamic tradition.

The Nubian Kingdoms (Sudan)

South of Egypt, in the land known as Nubia (modern-day Sudan), lay three powerful kingdoms: Nobatia, Makuria, and Alodia. During the 6th century, missionaries dispatched from Constantinople by Empress Theodora (who favored the Miaphysite faith) and Emperor Justinian (who favored the Chalcedonian faith) competed to convert these kingdoms. Ultimately, all three Nubian kingdoms embraced Christianity.

These kingdoms developed a unique and vibrant Christian culture, with beautiful frescoes and a distinct liturgy. Remarkably, these Christian Nubian kingdoms would endure for centuries after the Islamic conquest of Egypt, acting as a Christian bastion in Northeast Africa until the 13th-15th centuries.

To provide a clear overview, the table below summarizes the key information about these pre-Islamic Christian lands.

Conclusion: A Lost World and an Enduring Legacy

The world on the eve of Islam was a Christian world in ways that are often difficult for us to imagine today. The faith was not a European import to the Middle East and Africa; it was an indigenous, deeply rooted religion that had shaped the culture, politics, and identity of these regions for centuries. From the imperial grandeur of Constantinople to the monastic cells in the Egyptian desert, from the ancient highlands of Armenia to the bustling courts of Christian Arab kings, Christianity was diverse, dynamic, and dominant.

Understanding which countries were Christian before Islam is therefore not just a historical exercise. It is a crucial act of remembrance. It helps us appreciate the profound civilizational shift that occurred in the 7th century and provides essential context for the history that followed. It also shines a light on the incredible resilience of the ancient Christian communities—the Copts, Syriacs, Armenians, Assyrians, and others—who have maintained their faith and identity in their ancestral homelands to this very day, serving as a living link to this lost world of pre-Islamic Christendom.
