Moreover, he outlawed female genital mutilation, forced marriages and polygamy. He appointed women to high governmental positions and encouraged them to work outside the home and stay in school, even if pregnant. Sankara encouraged the prosecution of officials accused of corruption, counter-revolutionaries and "lazy workers" in Popular Revolutionary Tribunals.

Such programs led to criticism by Amnesty International and other non-governmental organizations for violations of human rights, including extrajudicial executions and arbitrary detentions of political opponents.
