Chaldean Catholic Eparchy of Amadiyah and Zaku

Chaldean Catholic Diocese of Zakho is a diocese of the Chaldean Church in the second half of the 19th century and for most of the 20th century. The diocese of Zakho was merged with the Chaldean diocese of ʿAmadiya in 1987. In December 2001, a new bishop was consecrated. In July 2013, Zakho was suppressed to the Diocese of Amadiyah.

Background
The diocese of Zakho was founded in 1851. The diocese included some villages in the western Khabur valley and the mountains to the northeast of Zakho previously in the diocese of Gazarta, and several villages in the Dohuk district previously in the diocese of ʿAmadiya.

The Chaldean bishops of Zakho
The first Chaldean bishop of Zakho was Emmanuel Asmar (1859–75).

He was succeeded by Quriaqos Giwargis Goga, a monk of the monastery of Rabban Hormizd, who was born in Telkepe on 15 January 1820 and ordained a priest in 1855. According to Tfinkdji he was consecrated for Zakho on 25 July 1875 by the patriarch Joseph VI Audo, but a manuscript note gives the date of his consecration as 1 August 1875. In 1876 Quriaqos Giwargis Goga rebelled against the patriarch and installed himself in the village of Telkepe in the patriarchal diocese of Mosul, where he was supported by most of the village's priests. Following an appeal to the Vatican by Joseph Audo, the two rebels eventually submitted, and Goga was transferred to the diocese of ʿAmadiya in 1879.

Quriaqos Goga was succeeded by Mattai Paul Shamina (1879–85) and Stephen Yohannan Qaynaya (1886–9).

Jeremy Timothy Maqdassi, who was born in Alqosh in 1847 and became a priest in 1879, was consecrated bishop of Zakho either in 1890 (De Clerq) or 1892 (Fiey), and remained its bishop until his death in 1929. He was succeeded by Peter Raffo ʿAziz (1929–37), Yohannan Nisan (1937–57), Thomas Rayyis (1957–66) and Gabriel Qoda (27 November 1965– 7 March 1968).

Gabriel Qoda, who died in March 1993, was succeeded as bishop of Zakho on 7 March 1968 by Joseph Babana. Joseph Babana died on 9 September 1973 at the age of 57, and was succeeded on 13 October 1973 by Yohannan Paulus Marcus.

The elderly Yohannan Paulus Marcus, who died on 13 July 1985 at the age of 75, was succeeded as bishop of Zakho by Stephen Kajo on 29 November 1983.

Following the death of Stephen Kajo on 8 November 1987, the diocese of Zakho remained vacant for fourteen years. During this period the few remaining Chaldeans in the Zakho district remained under the care of Yohannan Qello, the bishop of ʿAmadiya.

In December 2001 Petros Hanna Issa Al-Harboli was consecrated bishop of Zakho. After brief illness he died on November 3, 2010.

In July 2013, the Chaldean diocese of Amadiya was united with Zakho under Rabban al-Qas.
