Ethiopia is a country in the northeastern part of Africa, popularly known as the Horn of Africa. It shares borders with Eritrea to the north, Djibouti to the northeast, and Somalia to the east, Sudan to the northwest, South Sudan to the west, and Kenya to the south. With over 102 million inhabitants, Ethiopia is the most populous landlocked country in the world and the second-most populous nation on the African continent that covers a total area of 1,100,000 square kilometers (420,000 sq mi). Its capital and largest city is Addis Ababa, which lies a few miles west of the East African Rift that splits the country into the Nubian Plate and the Somali Plate.
Some of the oldest skeletal evidence for anatomically modern humans has been found in Ethiopia. It is widely considered as the region from which modern humans first set out for the Middle East and places beyond. According to linguists, the first Afroasiatic-speaking populations settled in the Horn region during the ensuing Neolithic era. Tracing its roots to the 2nd millennium BCE, Ethiopia’s governmental system was a monarchy for most of its history. Oral literature tells that the monarchy was founded by the Solomonic dynasty of the Queen of Sheba, under its first king, Menelik I. In the first centuries, the Kingdom of Aksum maintained a unified civilization in the region, followed by the Ethiopian Empire circa 1137.
