The Sabaeans were an ancient people speaking an Old South Arabian language who lived in what is today Yemen, in south west Arabian Peninsula; from 2000 BC to the 8th century BC. Some Sabaeans also lived in D'mt, located in northern Ethiopia and Eritrea, due to their hegemony over the Red Sea. They lasted from the early 2nd millennium to the 1st century BC. In the 1st century BC it was conquered by the Himyarites, but after the disintegration of the first Himyarite empire of the Kings of Saba' and dhu-Raydan the Middle Sabaean Kingdom reappeared in the early 2nd century. It was finally conquered by the Himyarites in the late 3rd century.
