Mongi Slim (Arabic: منجي سليم; September 15, 1908 – October 23, 1969)[1] was a Tunisian diplomat who became the first African to become the President of the United Nations General Assembly in 1961.

[2] Born on September 15, 1908, in Tunis, Slim came from an aristocratic family of Greek and Turkish origin.

One of Slim's great-grandfathers, a Greek named Kafkalas, was captured as a boy by pirates, and sold to the Bey of Tunis, who educated and freed him and then made him his minister of defense.

His paternal grandfather was an aristocratic Caid who ruled the wealthy province of Cape Bon.

[8] However, the Soviet Union favored U Thant of Burma, and secured a U.S. agreement to appoint him acting Secretary-General for the remainder of Hammarskjöld's term.
