Northeast Africa, or Northeastern Africa or Northern East Africa as it was known in the past, is a geographic regional term used to refer to the countries of Africa situated in and around the Red Sea. The region is intermediate between North Africa and East Africa, and mainly encompasses the Horn of Africa (Ethiopia, Eritrea, Somalia-Somaliland, Djibouti), The Sudans (Sudan, South Sudan), and Egypt, although sometimes its borders are stretched to either include Kenya, or Chad and Libya. The region has a very long history of habitation with fossil finds from the early hominids to modern human and is one of the most genetically and linguistically diverse regions of the world, being the home to many civilisations and located on an important trade route that connects multiple continents.[1][2][3][4][5]
