In the early 1990's, Rwanda was the African country in which a genocide occurred and lot of crimes against the humanity were done. The Hutu majority attacked the Tutsi minority, with the reason being an act of revenge because the Tutsi were controlling the country in the past and they owned the majority of the businesses. The United Nations didn't reacted to prevent this, nor it reacted while it was happening, which was very disappointing and against its own principles, and it only reacted after everything was over. Luckily for the Tutsi, they had their own army, and despite being smaller than the Hutu army, it was better trained and equipped, so they managed to stop full scale genocide and pushed back the Hutu forces.
