In 1970, 20 year old Sankara went on for further military studies at the military academy of Antsirabe (Madagascar), from which he graduated as a junior officer in 1973. At the Antsirabe academy, the range of instruction went beyond standard military subjects, which allowed Sankara to study agriculture, including how to raise crop yields and better the lives of farmers—themes he later took up in his own administration and country. During that period, he read profusely on history and military strategy, thus acquiring the concepts and analytical tools that he would later use in his reinterpretation of Burkinabe political history.
