Flavian of Constantinople was the Archbishop of Constantinople from 446 until his death in 449. A former presbyter and guardian of sacred vessels, he was chosen to lead the church during a period of intense theological conflict. His tenure was defined by his opposition to Eutyches, a dispute that led to a series of controversial ecclesiastical councils. Following his deposition and subsequent physical assault during the Second Council of Ephesus, he died in Lydia, an event that resulted in his recognition as a martyr.
