African Great Lakes
The African Great Lakes are a series of lakes constituting the part of the Rift Valley lakes in and around the East African Rift. They include Lake Victoria, the second largest fresh water lake in the world in terms of surface area; and Lake Tanganyika, the world's second largest in volume as well as the second deepest. The term Greater Lakes is also used, less commonly, for some of them.
The African Great Lakes are divided among three different catchments (river basins), and a number, such as Lake Turkana, have internal drainage systems. The following, in order of size from largest to smallest, are included on most lists of the African Great Lakes:
Some call only Lake Victoria, Lake Albert, and Lake Edward the Great Lakes, as they are the only three that empty into the White Nile. Lake Kyoga is part of Great Lakes system, but is not itself considered a Great Lake, based on size alone. Lake Tanganyika and Lake Kivu both empty into the Congo River system, while Lake Malawi is drained by the Shire River into the Zambezi. Lake Turkana has no outlet.
Because the term is a loose one, it is often preferable to use other categorizations such as African Rift Valley Lakes or East African Lakes.
African Great Lakes region 
The African Great Lake region is likewise somewhat loose. It is used in a narrow sense for the area lying between northern Lake Tanganyika, western Lake Victoria, and lakes Kivu, Edward and Albert. This comprises Burundi, Rwanda, north-eastern DR Congo, Uganda and north-western Kenya and Tanzania. It is used in a wider sense to extend to all of Kenya and Tanzania, but not usually as far south as Zambia, Malawi and Mozambique nor as far north as Ethiopia, though these four countries border one of the Great Lakes.
Because of the density of population and the agricultural surplus in the region the area became highly organized into a number of small states. The most powerful of these monarchies were Rwanda, Burundi, Buganda, and Bunyoro. Unusual for sub-Saharan Africa, the traditional borders were largely maintained by the colonial powers.
Being the long sought after source of the Nile, the region had long been of interest to Europeans. The first Europeans to arrive in the region in any numbers were missionaries who had limited success in converting the locals, but did open the region to later colonization. The increased contact with the rest of the world led to a series of devastating epidemics affecting both humans and livestock. These decreased the region's population dramatically, by up to 60% in some areas. The region did not return to its precolonial population until the 1950s. While seen as a region with great potential after independence, the region has in recent decades been marred by civil war and conflict, from which only Tanzania has largely escaped. The worst affected areas have been left in great poverty.
