The Coptic Catholic Patriarchate of Alexandria is the Patriarchal and only Metropolitan see of the head of the Eastern sui iuris Coptic Catholic Church, a particular Church in the Catholic Church in full communion with the Holy See, which follows the Alexandrian Rite in its own Coptic language. He is thus the superior of all Coptic dioceses, mostly in and around Egypt (where all its sees are), Copt(ic) being corruptions of the Greek word for Egypt(ian).
It has two cathedral archiepiscopal sees, both in Egypt: one dedicated to Notre-Dame of Egypte, in national capital Cairo, the other dedicated to the Resurrection, in Ancient Alexandria.
It had three false starts, each failing to prove enduring.
In 1947 it is restored for good as Patriarchal See of Alexandria / Alexandrin(us) Coptorum (Latin).
It lost territories in Egypt repeatedly to establish suffragan sees of Alexandria as Metropolitan :
It enjoyed a Papal visit from Pope John Paul II in February 2000.
The patriarchal see as such ranks third among all Catholic (arch)bishoprics of the world (only after the Pope's Holy See and the Catholic Patriarch of Constantinople), by the virtue of Canon Law (CCEO 58, 59.2).
Nevertheless, the incumbent Patriarch is likely to be outranked by many or even most Cardinals, whose higher rank as Princes of the Church is normally not (formally) linked to a see.
