Answer
Financial austerity measures led to the overthrow of Yaméogo's regime. In 1966, Yaméogo implemented austerity measures to address the country's financial problems. These measures included raising taxes, cutting government spending, and devaluing the currency. The austerity measures were unpopular with the people, and they led to widespread protests and demonstrations. In November 1966, a group of military officers led by Sangoulé Lamizana overthrew Yaméogo's government.
