The first president of Senegal was Léopold Sédar Senghor, who served from 1960 (when Senegal gained independence from France) until 1980. Senghor was not only a statesman but also a renowned poet and one of the founders of the Négritude literary movement, which celebrated African identity and culture. He is one of the most important francophone African figures studied in French-language curricula.
The other options name real Senegalese political figures but were not the first president: Abdou Diouf succeeded Senghor as the second president (1981-2000); Abdoulaye Wade served as the third president (2000-2012). Moussa Dieng is not a president of Senegal.
For francophone African studies, it is essential to know the founding presidents of major French-speaking African nations, especially Senghor for Senegal and his contributions to francophone literature.
