Armenian Patriarchate of Constantinople

The Armenian Patriarchate of Constantinople (Turkish: İstanbul Ermeni Patrikhanesi; Western Armenian: Պատրիարքութիւն Հայոց Կոստանդնուպոլսոյ, Badriark'ut'iun Hayots' Gosdantnubolsoy) is an autonomous see of the Armenian Apostolic Church. The seat of the Armenian Patriarch of Constantinople (French: Patriarche de Constantinople, Turkish: Konstantinopolis Ermeni Patriği), also known as Armenian Patriarch of Istanbul, is the Surp Asdvadzadzin Patriarchal Church (Holy Mother of God Patriarchal Church) in the Kumkapı neighborhood of Istanbul.

The patriarchate is one of the smallest of the Oriental Orthodox Churches but one that has exerted a very significant political role and today still exercises a spiritual authority. The Armenian Patriarchate of Constantinople recognizes the primacy of the Catholicos of All Armenians, in the spiritual and administrative headquarters of the Armenian Church, the Etchmiadzin, Armenia, in matters that pertain to the worldwide Armenian Apostolic Church. In local matters, the patriarchal see is autonomous.
