In 1960, Baudouin declared the Belgian colony of Congo independent. During the declaration of independence, Baudouin delivered a highly contested speech in which he celebrated the acts of the first Belgian owner of the Congo, King Leopold II, whom he described as "a genius". In the same event on the day of the independence, the first democratically elected prime minister of Congo, Patrice Lumumba, answered in a speech that was very critical of the Belgian regime. Lumumba mentioned the killing of many Congolese, the insults and humiliations and the slavery they suffered.
