Byzantium; in medieval Russian texts, Tsar’grad; capital of the Roman Empire from A.D. 330 and later of the Byzantine Empire.

Constantinople was founded by the Roman emperor Constantine I in 324–330 on the site of the city of Byzantium on the European shore of the Bosporus. The capital of the Roman Empire was transferred to Constantinople (the official date was May 11, 330) because of the proximity of Constantinople to the rich eastern provinces, its favorable commercial and strategic military position, and the absence there of senatorial opposition. Constantinople was a major economic and cultural center where class contradictions were concentrated. (The most important popular uprising in the city’s history was the Nika revolt of 532.)

Despite the economic decline experienced by the Byzantine Empire from the end of the seventh century, the economic importance of Constantinople grew, since most of the Byzantine cities lost their urban character and much of the commercial and industrial production was concentrated primarily in Constantinople. Until the end of the 11th century Constantinople politically and economically dominated the country. In the 12th century crafts and commerce began to decline in the city. This phenomenon was hastened by the appearance in Constantinople of Italian merchants who settled in one of the city’s districts, Galata. In April 1204, Constantinople was captured and plundered by participants in the Fourth Crusade. The city became the capital of the Latin Empire created by the Crusaders in 1204; economic primacy within it went to the Venetians. In July 1261, the Byzantines, with the assistance of the Genoese, won back Constantinople.

Until the middle of the 14th century Constantinople remained a major commercial center, then it gradually became desolate; within the city, the Venetians and Genoese seized the key positions. From the end of the 14th century the Turks tried to take the city several times. In May 1453, after a lengthy siege, Turkish troops occupied the city. Constantinople was renamed Istanbul and became the capital of Turkey (until 1923).
