The Turkish National Movement enters Constantinople.

The Turkish National Movement, also known as the Anatolian Movement, the Nationalist Movement, and the Kemalists, included political and military activities of the Turkish revolutionaries that resulted in the creation and shaping of the modern Republic of Turkey, as a consequence of the defeat of the Ottoman Empire in World War I and the subsequent occupation of Constantinople and partitioning of the Ottoman Empire by the Allies under the terms of the Armistice of Mudros. The Turkish revolutionaries rebelled against this partitioning and against the Treaty of Sèvres, signed in 1920 by the Ottoman government. Most revolutionaries were former members of the Committee of Union and Progress.

Constantinople was a historical city located on the Bosporus that served as the capital of the Roman, Byzantine, Latin and Ottoman empires between its consecration in 330 and 1930, when it was renamed Istanbul. Initially as New Rome, Constantinople was founded in 324 during the reign of Constantine the Great on the site of the existing settlement of Byzantium and in 330 became the capital of the Roman Empire. Following the collapse of the Western Roman Empire in the late 5th century, Constantinople remained the capital of the Eastern Roman Empire, the Latin Empire (1204–1261) and the Ottoman Empire (1453–1922). Following the Turkish War of Independence, the Turkish capital moved to Ankara. Although the city had been known as Istanbul since 1453, it was officially renamed Istanbul on 28 March 1930. The city is today the largest city in Europe, straddling the Bosporus strait and lying in both Europe and Asia, and the financial center of Turkey.
