East Africa or Eastern Africa is the easterly region of the African continent, variably defined by geography or geopolitics. In the United Nations Statistics Division scheme of geographic regions, 20 territories constitute Eastern Africa:
Due to colonial territories of the British East Africa Protectorate and German East Africa, the term East Africa is often (especially in the English language) used to specifically refer to the area now comprising the three countries of Kenya, Tanzania and Uganda. However, this has never been the convention in many other languages, where the term generally had a wider, strictly geographic context and therefore typically included Djibouti, Eritrea, Ethiopia, and Somalia.
Some parts of East Africa have been renowned for their concentrations of wild animals, such as the "big five" of elephant, buffalo, lion (particularly the Ugandan, Masai and Ethiopian ones),leopard and black rhinoceros, though populations have been declining under increased stress in recent times, particularly the rhino and elephant.
The geography of East Africa is often stunning and scenic. Shaped by global plate tectonic forces that have created the East African Rift, East Africa is the site of Mount Kilimanjaro and Mount Kenya, the two tallest peaks in Africa. It also includes the world's second largest freshwater lake Lake Victoria, and the world's second deepest lake Lake Tanganyika.
