It is directly dependent on the Syriac Catholic Patriarch of Antioch and the Roman Congregation for the Oriental Churches), not part of any ecclesiastical province.
The cathedral of the Assumption of Mary in Hasakah is its archiepiscopal see.
Established on 17 July 1957 as Eparchy of Hasakah (Diocese), on Syriac territory previously without proper Ordinary for the particular church sui iuris.
Promoted on 3 December 1964 as Archdiocese of HasakahâÂÂNisibi(s) (Archdiocese), adopting as honorary second title Nisibi(s), a grand old, suppressed Metropolitan see which has titular archbishopric successor sees in four other Catholic rites but never was a Syriac Catholic diocese.
