This research paper explores the evolution of the Senegalese government immediately after independence and the various factors contributing to its remarkable stability. It begins with a brief look at Senegal’s history, both pre-colonial and colonial. The research then discusses the foundations of the Senegalese government structure and party system from just before independence to 1978. The highlighted elements of the story are the role of political parties and single-party dominance, Senghor’s platform based on African socialism and négritude, and the formation and failure of the Mali Federation. This work also features party building, social groups that influence politics, the urban-rural cleavage, and some constitutional development. The focus of the research is on Léopold Sédar Senghor, the key figure in the stable governmental establishment in Senegal. It explores his relations with other key figures including Lamine Guèye, the facilitator of socialism’s rise in Senegal and a major party leader, and Mamadou Dia, once a friend of Senghor’s and his Prime Minister, who attempted a nonviolent coup; he was foiled and jailed in 1962. The various clans of Senegal (based on heredity) and the Islamic Brotherhoods, powerful religious organizations that have much sway over their members’ political attitudes, also play an important role. This paper concludes with an exploration of Senghor’s dynamic leadership as a foundation for political stability in Senegal, focusing on two major events: the disintegration of the extremely short-lived Mali Federation and the resulting independence of Senegal, and Dia’s attempted coup and resulting arrest. The constitution was amended after Dia’s jailing in 1962 to remove the post of prime minister, leaving the president as the sole head of government, and increasing Senghor’s power and influence. The remainder of the research after the failed coup consists of exploring the ways in which Senghor made his party completely dominant and his role and contributions as president.
