He immediately launched programmes for social, ecological and economic change and renamed the country from the French colonial name Upper Volta to Burkina Faso ("Land of Incorruptible People"), with its people being called Burkinabé ("upright people"). His foreign policies were centred on anti-imperialism, with his government refusing all foreign aid, pushing for odious debt reduction, nationalising all land and mineral wealth and averting the power and influence of the International Monetary Fund and World Bank. His domestic policies were focused on preventing famine with agrarian self-sufficiency and land reform, prioritising education with a nationwide literacy campaign and promoting public health by vaccinating 2.5 million children against meningitis, yellow fever and measles.
