Chaldean Catholic Archeparchy of Kirkuk-Sulaimaniya
The foundation of the Chaldean Catholic diocese of Kirkuk has been attributed to Yohannan VIII Hormizd, who was recognised by the Vatican as patriarchal administrator of the patriarch of Babylon in 1780 and, after five decades of disputes and confrontations, as patriarch in 1830. According to the Chaldean Catholic priest Joseph Tfinkdji, Yohannan Hormizd visited the town of Kirkuk in 1789 while travelling from Mosul to Baghdad, and converted its Church of the East community to Catholicism. He is said to have consecrated a Chaldean metropolitan for Kirkuk, Mar Abraham, who resided in Aïnqawa during his reign, and died between 1821 and 1824. The source for this assertion is not clear. Abraham is not mentioned by any other source, and as Yohannan Hormizd himself (then considered by the Vatican to be merely metropolitan of Mosul) is styled 'metropolitan of Kirkuk' in a colophon of 1798, the Kirkuk region would seem to have been part of the diocese of Mosul at this period.
Maronite Church
Maron established himself in the remote Qadisha Valley in Lebanon. In 694, Justinian sent troops against the Maronites in an unsuccessful attempt to capture the Patriarch. Maron died in 707 at the Monastery of St. Maron in Lebanon. Around 749 the Maronite community, in the Lebanon mountains, built the Mar-Mama church at Ehden. Meanwhile, caught between the Byzantines and the Arabs, the monastery at Beth-Maron struggled to survive.
