The long downfall of the Byzantine Empire

The long downfall of the Byzantine Empire was a slow, agonizing decline that stretched over several centuries, driven by relentless external pressures and deep-seated internal decay. Once a dominant superpower, the empire was gradually hollowed out by devastating civil wars, economic mismanagement, and the loss of its rich Anatolian breadbasket to the Seljuk Turks after the disastrous Battle of Manzikert in 1071. The fatal blow to its integrity came from within Christendom during the Fourth Crusade in 1204, when Western crusaders sacked Constantinople, fracturing the empire into competing remnants from which it never fully recovered. Though the Byzantines eventually reclaimed their capital, they ruled over a ghost of their former realm,impoverished, depopulated, and geographically isolated. By the 15th century, Byzantium had been reduced to little more than a city-state, entirely surrounded by the rising Ottoman Empire, which finally brought the millennium-old Roman successor state to an end with the historic fall of Constantinople in 1453.
