Copts
The Copts are an ethno-religious group situated in North Africa and the Middle East, mainly in the area of modern Egypt, where they are the largest Christian denomination. They are also the largest Christian denomination in Sudan and Libya. Christianity was the religion of the vast majority of Egyptians from 400–800 A.D. and the majority after the Muslim conquest until the mid-10th century and remains the faith of a significant minority population. Historically they spoke the Coptic language, a direct descendant of the Demotic Egyptian spoken in the Roman era, but it has been near-extinct and mostly limited to liturgical use since the 18th century. They now speak Arabic.Copts in Egypt constitute the largest Christian community in the Middle East, as well as the largest ethno-religious minority in the region, accounting for an estimated 10% of the Egyptian population.
