Marcian was Roman emperor of the East from 450 to 457. Very little is known of his life before becoming emperor, other than that he was a domesticus who served under the commanders Ardabur and his son Aspar for fifteen years. After the death of Emperor Theodosius II on 28 July 450, Marcian was made a candidate for the throne by Aspar, who held much influence because of his military power. After a month of negotiations Pulcheria, Theodosius' sister, agreed to marry Marcian. Zeno, a military leader whose influence was similar to Aspar's, may have been involved in these negotiations, as he was given the high-ranking court title of patrician upon Marcian's accession. Marcian was elected and inaugurated on 25 August 450.
