Rwandan Genocide – Wikipedia, the free encyclopedia
Following the Berlin Conference, held in 1885, Rwanda and Burundi were ceded to Germany, who held it until the 1918 Treaty of Versailles, when it was ceded to Belgium.[6] The Belgians seeking a non-indigenous explanation for the complex monarchy they found in the colony, framed the Hutu/Tutsi distinction as one of race, rather than economics or ethnicity. The Belgians issued racial identification cards to every Rwandan, giving preferential treatment to Tutsis for positions in education, politics and business.
