Constantine the Great

Also called: Constantine I

Roman emperor (r. 306–337) who legalised Christianity with the Edict of Milan (313), called the Council of Nicaea and moved the capital to Constantinople

Son of Constantius, a junior emperor of the Tetrarchy, he was proclaimed emperor by the army in Britain in 306. He defeated Maxentius at the Milvian Bridge in 312 to win the west, and overcame Licinius in 324 to rule the whole empire again. He stabilised the currency with the gold solidus and bound tenant farmers (coloni) to the land to secure taxes. In 330 he moved the capital to Constantinople, shifting the empire’s centre to the east. He was baptised shortly before his death.
