Mar Ignatius Andrew AbdulGhal Akijan was the Patriarch of the Syriac Catholic Church from 1662 to 1677. His election as Patriarch marked the first separation of the hierarchy between the Syriac Catholic Church and the Syriac Orthodox Church.
Andrew Akijan was born in 1622 in Mardin and soon came in contact with the Carmelites missionaries. He studied from 1649 in the Maronite College in Rome and after three years he returned in the East where he was ordained priest in 1652 by the Maronite Patriarch.
