The Léopoldville riots were an outbreak of civil disorder in Léopoldville (modern-day Kinshasa) in the Belgian Congo which took place in January 1959 and which were an important moment for the Congolese independence movement. The rioting occurred when members of the Alliance des Bakongo (ABAKO) political party were not allowed to assemble for a protest and colonial authorities reacted harshly. The exact death toll is not known, but at least 49 people were killed and total casualties may have been as high as 500. Following these riots, a round table conference was organized in Brussels to negotiate the terms of Congo's independence, The Congo received its independence on 30 June 1960, becoming the Republic of the Congo. Background Colonial rule in the Congo began in the late 19th century. King Leopold II of Belgium, frustrated by Belgium's lack of international power and prestige, attempted to persuade the Belgian government to support colonial expansion around the largely unexplored Congo Basin. The Belgian government's ambivalence about the idea led Leopold to eventually create the colony on his own account. With support from a number of Western countries, who viewed Leopold as a useful buffer between rival colonial powers, Leopold achieved international recognition for a personal colony, the Congo Free State, in 1885. By the turn of the century, however, the violence of Free State officials against indigenous Congolese and the ruthless system of economic extraction had led to intense diplomatic pressure on Belgium to take official control of the country, which it did in 1908, creating the Belgian Congo. During the latter stages of World War II a new social stratum emerged in the Congo, known as the évolués. Forming an African middle class in the colony, they held skilled positions (such as clerks and nurses) made available by the economic boom. While there were no universal criteria for determining évolué status, it was generally accepted that one would have "a good knowledge of French, adhere to Christianity, and have some form of post-primary education." Up into the 1950s most évolués were concerned only with social inequalities and their treatment by the Belgians. Nationalism grew in 1958 as more évolués began interacting with others outside of their own locales and started discussing the future structures of a post-colonial Congolese state. A slew of new political parties competed for popular support, including the Alliance des Bakongo (ABAKO), led by Joseph Kasa-Vubu and the
