Constantinople
Constantinople (; ) was the capital city of the Roman/Byzantine Empire (330–1204 and 1261–1453), and also of the brief Crusader state known as the Latin Empire (1204–1261), until finally falling to the Ottoman Empire (1453–1923). It was reinaugurated in 324 from ancient Byzantium as the new capital of the Roman Empire by Emperor Constantine the Great, after whom it was named, and dedicated on 11 May 330. The city was located in what is now the European side and the core of modern Istanbul.
Byzantine art
Two events were of fundamental importance to the development of a unique, Byzantine art. First, the Edict of Milan, issued by the emperors Constantine I and Licinius in 313, allowed for public Christian worship, and led to the development of a monumental, Christian art. Second, the dedication of Constantinople in 330 created a great new artistic centre for the eastern half of the Empire, and a specifically Christian one. Other artistic traditions flourished in rival cities such as Alexandria, Antioch, and Rome, but it was not until all of these cities had fallen - the first two to the Arabs and Rome to the Goths - that Constantinople established its supremacy.
