Early Christianity became the established church of the Ethiopian Axumite Kingdom under king Ezana in the 4th century when priesthood and the sacraments were brought for the first time through a Syrian Greek named Frumentius, known by the local population in Ethiopia as "Selama, Kesaté Birhan" ("Father of Peace, Revealer of Light"). As a youth, Frumentius had been shipwrecked with his brother Aedesius on the Eritrean coast. The brothers managed to be brought to the royal court, where they rose to positions of influence and baptized Emperor Ezana. Frumentius is also believed to have established the first monastery in Ethiopia, named Dabba Selama after him. In 2016, scientists excavated a 4th-century AD basilica (radio-carbon dated) in northeastern Ethiopia at a site called Beta Samati. This is the earliest known physical evidence of a church in sub-Saharan Africa.
