He entered the military academy of Kadiogo in Ouagadougou with the academy's first intake of 1966 at the age of 17. While there he witnessed the first military coup d'état in Upper Volta led by Lieutenant-Colonel Sangoulé Lamizana (3 January 1966). The trainee officers were taught by civilian professors in the social sciences. Adama Touré, who taught history and geography and was known for having progressive ideas, even though he did not publicly share them, was the academic director at the time. He invited a few of his brightest and more political students, among them Sankara, to join informal discussions about imperialism, neocolonialism, socialism and communism, the Soviet and Chinese revolutions, the liberation movements in Africa and similar topics outside of the classroom. This was the first time Sankara was systematically exposed to a revolutionary perspective on Upper Volta and the world. Aside from his academic and extracurricular political activities, Sankara also pursued his passion for music and played the guitar.
