Context: Christian missions established Western educational institutions in the Protectorates. Under Britain's policy of indirect rule and validation of Islamic tradition, the Crown did not encourage the operation of Christian missions in the northern, Islamic part of the country. Some children of the southern elite went to Great Britain to pursue higher education. By independence in 1960, regional differences in modern educational access were marked. The legacy, though less pronounced, continues to the present-day. Imbalances between North and South were expressed in Nigeria's political life as well. For instance, northern Nigeria did not outlaw slavery until 1936 whilst in other parts of Nigeria slavery was abolished soon after colonialism.
