When and how did the Byzantine Empire fall?
The Byzantine Empire, sometimes referred to as the Eastern Roman Empire, stood as a beacon of Christian civilization and Hellenistic culture for over a millennium. Rooted in the 4th century AD with the foundation of Constantinople by Emperor Constantine the Great, it finally succumbed in 1453 to the Ottoman Turks. The story of its fall is one of resilience, external pressures, internal strife, and changing geopolitical dynamics.
Initial Pressures and Resilience
Through its long history, the Byzantine Empire faced numerous threats, from Persian invasions in the 6th and 7th centuries to Arab sieges in the 8th century. Each time, the empire demonstrated a remarkable ability to adapt and survive, often through diplomacy, strategic retreats, and, when necessary, military action.
Rise of Islam and Loss of Territories
One of the most significant threats to Byzantium came with the rapid spread of Islam. By the end of the 7th century, Arab forces had stripped the empire of its Middle Eastern and North African territories. These losses included crucial regions like Egypt, the empire’s breadbasket.
In the 8th and 9th centuries, the empire was internally fractured by the Iconoclast Controversy, a theological and political debate over the use of religious images. These internal disputes weakened the empire both socially and politically, leading to further territorial losses in the Balkans and Italy.
Revival under the Macedonian Dynasty
The late 9th to early 11th centuries saw a Byzantine resurgence under the Macedonian dynasty. The empire regained lost territories and established a period of relative peace, cultural flourishing, and administrative efficiency.
Arrival of the Seljuk Turks
However, this revival was short-lived. The Battle of Manzikert in 1071, where the Byzantine forces were defeated by the Seljuk Turks, marked a pivotal point. With this loss, Anatolia, the empire’s heartland, became open to Turkish settlement. This marked the rise of Turkish power in the region and signified the gradual Turkification of Anatolia.

While the Byzantine emperors sought assistance from the West against the Seljuks, the response came in an unintended manner: the Crusades. The Fourth Crusade (1202-1204) was particularly devastating when, instead of heading to the Holy Land, the crusaders turned on Constantinople, looting the city and establishing the short-lived Latin Empire in 1204. Though the Byzantines would recapture the city in 1261, the empire was a shadow of its former self.

Rise of the Ottoman Turks
By the late 13th century, a new Turkish power was emerging in the region: the Ottoman Turks. Under their charismatic leader, Osman I, they began to consolidate power, seizing Byzantine territories. By the mid-14th century, they had made significant inroads into the Balkans and effectively surrounded Constantinople.
Attempts at Western Assistance
As the situation grew dire, the Byzantines again looked westward for assistance. At the Council of Florence in 1439, the Byzantines, represented by Emperor John VIII Palaiologos, agreed to church reunification, hoping this would rally Western support. Unfortunately, while the theological differences were temporarily bridged, military aid was limited.
The Siege of 1453
By the 15th century, the once-magnificent Byzantine Empire was reduced to Constantinople and a few scattered territories. Sultan Mehmed II (also known as Mehmed the Conqueror), the ambitious leader of the Ottomans, set his sights on the city. In April 1453, he laid siege to Constantinople with a force that, by some accounts, numbered over 100,000, bolstered by heavy cannons.
The Byzantines, under Emperor Constantine XI Palaiologos, made a valiant defense. The massive Theodosian Walls, which had protected the city for a millennium, were bombarded relentlessly by Ottoman cannons. On May 29, 1453, after a 53-day siege, the city fell. Constantine XI, the last Byzantine Emperor, died fighting on the walls.
With the conquest of Constantinople, the Byzantine Empire officially came to an end, and the city was renamed Istanbul. The Ottomans made it their capital, marking the beginning of a new era where the city would thrive as the heart of a vast and influential empire.
The legacy of Byzantium, however, lived on. Its influence in art, theology, and culture permeated into the Renaissance through fleeing scholars who brought ancient texts and knowledge to the West. Furthermore, the Orthodox Christian tradition continued to flourish in Greece, Russia, and other parts of the Orthodox world.
