who controlled the city of constantinople at the end of the crusades
Sack of Constantinople (1204) The Sack of Constantinople or Siege of Constantinople occurred in 1204 and marked the culmination of the Fourth Crusade. Mutinous Crusader armies captured, looted, and destroyed parts of Constantinople, the capital of the Byzantine Empire. After the capture, the Latin Empire was established and Baldwin of Flanders was crowned Emperor Baldwin I of Constantinople in the Hagia Sophia.
Roman Empire Diocletian divided the empire into four regions, each ruled by a separate emperor, the Tetrarchy.[27] Confident that he fixed the disorders that were plaguing Rome, he abdicated along with his co-emperor, and the Tetrarchy soon collapsed. Order was eventually restored by Constantine the Great, who became the first emperor to convert to Christianity, and who established Constantinople as the new capital of the eastern empire. During the decades of the Constantinian and Valentinian dynasties, the empire was divided along an eastâ€“west axis, with dual power centres in Constantinople and Rome. The reign of Julian, who attempted to restore Classical Roman and Hellenistic religion, only briefly interrupted the succession of Christian emperors. Theodosius I, the last emperor to rule over both East and West, died in 395 AD after making Christianity the official religion of the empire.[28]
Walls of Constantinople Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, when well-manned, they were almost impregnable for any medieval besieger, saving the city, and the Byzantine Empire with it, during sieges from the Avar-Sasanian coalition, Arabs, Rus', and Bulgars, among others. The advent of gunpowder siege cannons rendered the fortifications vulnerable, but cannon technology was not sufficiently advanced to capture the city on its own, and the walls could be repaired between reloading. Ultimately the city fell from sheer weight of numbers of the Ottoman forces on 29 May 1453 after a six-week siege.
