By 1801, Europe only controlled a few colonies in Africa, India, and South East Asia, while the Russians and Turks are competing for the control of Caucasus, Britain is expanding from India into Central Asia competing against the Russians. Except for a few colonies in the South and the North of Africa, Africa is mostly unexplored by Europeans. A few kingdoms in West Africa provide slave labor to the Americas, and the Ottomans control most northern Africa.
