Eastern Roman emperor from 457 to 474
b. c. 401 · d. 19 Jan 474
Leo I, also known as the Thracian, was Eastern Roman emperor from 457 to 474. He was a native of Dacia Aureliana near historic Thrace. He is sometimes surnamed with the epithet the Great, probably to distinguish him from his young grandson and co-augustus Leo II.
