Léopold Sédar Senghor (9 October 1906 – 20 December 2001) was a Senegalese poet, politician and cultural theorist who was the first president of Senegal (1960–80).
Ideologically an African socialist, he was the major theoretician of Négritude. Senghor was a proponent of African culture, black identity and African empowerment within the framework of French-African ties. He advocated for the extension of full civil and political rights for France's African territories while arguing that French Africans would be better off within a federal French structure than as independent nation-states.
Senghor became the first President of independent Senegal. He fell out with his long-standing associate Mamadou Dia who was Prime Minister of Senegal, arresting him on suspicion of fomenting a coup and imprisoning him for 12 years. Senghor established an authoritarian single-party state in Senegal where all rival political parties were prohibited.
