Ignatius Zakka I Iwas was the 122nd reigning Syriac Orthodox Patriarch of Antioch and All the East and, as such, Supreme Head of the Universal Syriac Orthodox Church. Also known by his traditional episcopal name, Severios, he was enthroned as patriarch on 14 September 1980 in St. George's Patriarchal Cathedral in Damascus. He succeeded Ignatius Ya`qub III. As is traditional for the head of the church, Mor Severios adopted the name Ignatius.

The Syriac Orthodox Church, also known as West Syriac Church or West Syrian Church, officially known as the Syriac Orthodox Patriarchate of Antioch and All the East, and informally as the Jacobite Church, is an Oriental Orthodox church that branched from the Church of Antioch. The bishop of Antioch, known as the patriarch, heads the church and possesses apostolic succession through Saint Peter, according to sacred tradition. The church upholds Miaphysite doctrine in Christology, and employs the Liturgy of Saint James, associated with James the Just. Classical Syriac is the official and liturgical language of the church.
