anti-colonial leaders as Kwame Nkrumah from Ghana and Egyptian President Gamel Abdel Nasser. Only by aligning himself with his erstwhile enemy, the more radical Jacques Opangault in the parliamentary elections of March 31, 1957 could he continue to play a leading role in Congolese political life. Prior to independence, the French establishment and Catholic Church feared Opangault's radicalism and favored the rise of Fulbert Youlou, a former priest. The defection of Georges Yambot from the African Socialist Movement (MSA) to Youlou's Union Démocratique pour la Défense d'Intérêts Africains (UDDIA) helped Youlou become prime minister in 1958. This led to the establishment of the Republic of the Congo on 28 November 1958 (with Brazzaville replacing Point Noire as the country's capital). On 16 February 1959, a revolt organized by Opangault and his MSA erupted in clashes along tribal lines between Southerners, supporting Youlou, and people from the North, loyal to the MSA. The riots were suppressed by French army and Opangault was arrested. In total about 200 people died. Prime Minister Youlou then held the elections for which Opangault had previously asked in vain. After the May 9 arrest of several politicians, including veteran politician Simon Kikhounga Ngot, because of an alleged communist plot, parliamentary elections were convincingly won by Youlou. On 12 July 1960 France agreed to Congo becoming fully independent. On 15 August 1960, the Republic of the Congo became an independent country and Fulbert Youlou became its first President. In November that year, Youlou released Opangault, Ngot and other adversaries, as part of an amnesty. In return both politicians, as well as Germain Bicoumat, joined Youlou's government and received ministerial posts, effectively destroying any organized political opposition. Oil Shortly before gaining independence an event occurred that in the years to come would have deep influence on the country and its relations with the outside world, mainly France. Although French geologists had already established for certain in 1926 the presence of oil and gas in the country, in 1957 near Pointe Indienne the French Societé des Pétroles de l'Afrique Equatoriale Françaises (SPAEF) found oil and gas reserves offshore in sufficient exploitable quantities. Only then did France start exploiting these reserves. The reason was that in Algeria a war of independence was fought, and the French were losing. Until then Algeria was the main source of oil and gas destined for the French market. To remain independent of the American
