In 1780, at the beginning of the patriarchal tenure of Eliya XII (XIII) (1778–1804), a group seceded from the Eliya line in Alqosh and elected Yohannan Hormizd, who entered full communion with the Catholic Church and was officially appointed Archbishop of Mosul and patriarchal administrator of the Chaldean Catholic Church, in 1783. Only after the death in 1827 of the last representative of the Josephite line, Joseph V Augustine Hindi, was Yohannan recognized as the Chaldean Catholic Patriarch by the Pope, in 1830. By this official appointment, the final merger of various factions committed to the union with the Catholic Church was achieved, thus forming the modern Chaldean Catholic Church.
