Ethiopia has close historical ties with all three of the world’s major Abrahamic religions. In the 4th century AD  it became one of the first areas of the world to officially adopt Christianity when St. Frumentius of Tyre, called Fremnatos or Abba Selama (“Father of Peace”) in Ethiopia, converted King Ezana, It still has a Christian majority, but over a third of the population is Muslim.
Ethiopia was the site of the first hajj in Islamic history when a group of Muslims were counseled by Muhammad to escape persecution in Mecca and travel to Ethiopia. The oldest Muslim settlement in Africa was at Negash. Muslims were given the right to practice their own religion in Ethiopia.
 A small group of Jews, the Beta Israel, live in northwestern Ethiopia, though most emigrated  to Israel in the last decades of the 20th century .Some Israeli and Jewish scholars consider these Ethiopian Jews as a historical Lost Tribe of Israel.
There are numerous indigenous African religions in Ethiopia, mainly located in the far southwest and western borderlands. In general, most Christians live in the highlands, while Muslims and adherents of traditional African religions tend to inhabit the lowland regions in the east and south of the country.
