Anastasius was born at Dyrrhachium (now Durres, Albania) about the year 430. His parents were Pompeius, a nobleman of Dyrrhachium, and Anastasia Constantina. His mother was an [[Arianism|Arian]]. Anastasius had one eye black and one eye blue (heterochromia), and for that reason was nicknamed ''Dicorus'' (Greek: Δίκορος, "two-pupiled").
Although not prominent, Anastasius was a member of emperor [[Zeno]]'s court, holding the position of silentiarius. Apparently he was well educated, particularly in theology such that he was considered in 488 for the position of bishop of Antioch. After the death of emperor Zeno in 491, his widow empress Ariadne supported Anastasius as Zeno's successor, even preferring him over Zeno's brother Longinus who had hoped to become emperor.
Anastasius was acclaimed emperor on [[April 11]], 491, and a month later he married Ariadne on [[May 20]] apparently on the initiative of Ariadne, despite his advanced age. Anastasius was 61. After ascending the throne, Anastasius exiled Longinus to Egypt and expelled many officials, especially Isaurians, from Constantinople. It took until 498 for him the suppress the Isaurian revolt following their expulsion. Anastasius was also confronted by hostilities in the Balkans and with the Persians throughout most of his reign.
