The Basutoland African Congress (BAC) was founded in 1952 by Ntsu Mokhehle and Potlako Leballo.
The next day Leballo was arrested while waiting to meet Edson Zvobgo, a government minister, imprisoned, and deported the next day.
In 1962, Potlako Leballo (1915–1986) left the country for Maseru, Basutoland, and became the PAC's acting president.
