It borders on Angola in the southwest and west, on Cabinda and the Republic of the Congo in the west, on the Central African Republic and Sudan in the north, on Uganda, Rwanda, Burundi, and Tanzania in the east, and on Zambia in the southeast.
Congo lies astride the equator, and virtually all of the country is part of the vast Congo River drainage basin.
In S Congo are highland plateaus (average elevation: c.3,000 ft/910 m; highest elevation: c.6,800 ft/2,070 m), which are covered with savanna.
Briefly, the successive stages of the foundation of the Congo Free State were as follows: As a consequence of the expeditions (1840; 1 May, 1873) of Livingstone and Stanley, public attention began to be drawn to Central Africa, and Leopold II divined the greatest possibilities of the newly-discovered country.
The innumerable rivers of the Congo are rocky in their upper courses and cut their way by rapids from one terrace to another, until, on the great alleuvial plains of the centre, they form an immense network of from 9,000 to 11,000 miles of navigable water-ways and spread out fan-like from Leopoldville.
In the Congo territory itself a governor-general is at the head of the administration.
