History of Cameroon 

Early history
The earliest inhabitants of Cameroon were probably the Baka . They still inhabit the forests of the south and east provinces. Bantu speakers originating in the Cameroonian highlands were among the first groups to move out before other invaders.
The Mandara kingdom in the Mandara Mountains was founded around 1500 and erected fortified structures, the purpose and exact history of which are still unresolved. The Aro Confederacy of Nigeria had a presence in Western Cameroon due to trade and migration in the 18th and 19th centuries.
During the late 1770s and the early 19th century, the Fulani, an Islamic pastoral people of the western Sahel, conquered most of what is now northern Cameroon, subjugating or displacing its largely non-Muslim inhabitants.
Although the Portuguese arrived on Cameroon's doorstep in the 16th century, malaria prevented significant European settlement and conquest of the interior until the late 1870s, when large supplies of the malaria suppressant quinine became available. The early European presence in Cameroon was primarily devoted to coastal trade and the acquisition of slaves. The northern part of the country was an important part of the Muslim slave trade network. The trade was largely suppressed by the mid-19th century. Christian missionaries established a presence in the late 19th century and continue to play a role in Cameroonian life.
Colonization
Beginning on July 5, 1884, all of present-day Cameroon and parts of several of its neighbours became a German colony, Kamerun, with a capital first at Buea and later at Yaoundé.
Germany was particularly interested in Cameroon's agricultural potential and entrusted large firms with the task of exploiting and exporting it. German Chancellor Otto von Bismarck defined the order of priorities as follows: "first the merchant, then the soldier". It was under the influence of a businessman Adolph Woermann, whose company set up a trading house in Douala, that Bismarck, initially skeptical about the interest of the colonial project, was convinced. Large German trading companies and concession companies established themselves massively in the colony. Letting the big companies
