Hormisdas was a 6th-century bishop of Rome who served as pope from 514 until his death in 523. Born in Frosinone, he was a prominent cleric during the Laurentian schism before his election. His papacy was defined by his diplomatic efforts to resolve the Acacian Schism, a long-standing division between the Eastern and Western churches. Through firm negotiations and specific theological demands, he successfully facilitated the reunification of the Sees of Rome and Constantinople, restoring communion between the two regions.
