Christianity in Ethiopia dates to the 1st century AD, and this long tradition makes Ethiopia unique amongst sub-Saharan African countries. Christianity in this country is divided into several groups. The largest and oldest is the Ethiopian Orthodox Tewahedo Church which is an Oriental Orthodox church in Ethiopia that was part of the Coptic Orthodox Church until 1959, when it was granted its own Patriarch by Coptic Orthodox Pope of Alexandria and Patriarch of All Africa Cyril VI. The only pre-colonial Christian church of Sub-Saharan Africa, the Ethiopian Orthodox church has a membership of slightly more than 32 million people in Ethiopia, and is thus the largest of all Oriental Orthodox churches. Next in size are the various Protestant congregations, who include 13.7 million Ethiopians. The largest Protestant group is the Ethiopian Evangelical Church Mekane Yesus, with about 5 million members. Roman Catholicism has been present in Ethiopia since the 16th century, and numbers 536,827 believers. In total, Christians make up about 60% of the total population of the country.
