Answer
Thomas Sankara, the charismatic leader of Burkina Faso, was assassinated in a coup d'état led by his former ally, Blaise Compaoré, on October 15, 1987. The coup ended Sankara's four-year presidency, marked by his progressive policies, anti-imperialist stance, and emphasis on social justice. Compaoré's actions brought significant political change to Burkina Faso and marked a shift away from Sankara's idealistic vision.
