Coptic Orthodox Christianity is the indigenous form of Christianity that, according to tradition, the apostle Mark established in Egypt in the middle of the 1st century AD (approximately 42). The Church belongs to the Oriental Orthodoxy, and the see of Alexandria in Coptic Christianity has been a distinct church body since the Council of Chalcedon in 451. It's leader is the Pope of Alexandria and the Patriarch of the Holy See of Saint Mark, currently Pope Shenouda III. More than 95% of Egypt's Christians belong to the Coptic Orthodox Church, but other "Patriarchates/Patriarchs of Alexandria" also exist (Coptic Catholic, Greek/Latin Catholic and Greek Orthodox - see Coptic Christianity Today below).
