Even after the British took control of Egypt, knowledge about the Nile remained sparse, most importantly the source of the river, and exploration all over the continent took place among adventurers of various nationalities. Other countries also sought to get a foothold on the continent, to the extent that near the end of the 19th century, Otto von Bismarck, the German chancellor, brought the plenipotentiaries of all major powers of Europe together to deal with Africa's colonization in such a manner as to avoid provocation of war. This event, known as the Berlin Conference of 1884-1885, galvanized a phenomenon that came to be known as the Scramble for Africa. The conference established two fundamental rules for European seizure of Africa. The first of these was that no recognition of annexation would granted without evidence of a practical occupation, and the second, that a practical occupation would be deemed unlawful without a formal appeal for protection made on behalf of a territory by its leader, a plea that must be committed to paper in the form of a legal treaty.
This began a rush, spearheaded mainly by European commercial interests in the form of Chartered Companies, to penetrate the African interior and woo its leadership with guns, trinkets and alcohol, and having thus obtained their marks or seals upon spurious treaties, begin establishing boundaries of future European African colonies. The ease with which this was achieved was due to the fact that, at that point, traditional African leadership was disunited, and the people had just staggered back from centuries of concussion inflicted by the slave trade. Thus, to usurp authority, to intimidate an already broken society, and to play one leader against the other was a diplomatic task so childishly simple, the matter was wrapped up, for the most part, in less than a decade. Even at that stage, however, the countries would keep jostling for position in Africa against each other.
