Determined to look for a colony for himself and inspired by recent reports from central Africa, Leopold began patronizing a number of leading explorers, including Henry Morton Stanley. Leopold established the International African Association, a charitable organization to oversee the exploration and surveying of a territory based around the Congo River, with the stated goal of bringing humanitarian assistance and civilization to the natives. In the Berlin Conference of 1884–85, European leaders officially recognized Leopold's control over the of the notionally-independent Congo Free State.
