Colonial Expansion, Indirect Rule
Britain governed Nigeria via indirect rule, a system in which native leaders continued to rule their traditional lands so long as they collected taxes and performed other duties ensuring British prosperity. Uncooperative or ineffective leaders were easily replaced by others who were more compliant or competent, and usually more than willing to enjoy the perks of government. Britain was thus saved the huge economic and political cost of running and militarily securing a day-to-day government.
Indirect rule operated relatively smoothly in the north, where the British worked with the Fulani aristocracy, who had long governed the Sokoto caliphate and who were able to administer traditional Islamic law alongside British civil law. In the south, however, traditions were less accommodating. In Yorubaland indirect rule disrupted historical checks and balances, increasing the power of some chiefs at the expense of others. Moreover, although the Yoruba kings had long been powerful, few had collected taxes, and citizens resisted their right to do so under British mandate. In the southeast, particularly in Igboland, many of the societies had never had chiefs or for that matter organized states. Consequently, the chiefs appointed by Britain received little or no respect. In Nigeria's culturally fragmented middle belt, small groups were forcefully incorporated into larger political units and often ruled by “foreign” Fulani, who brought with them alien institutions such as Islamic law.
The British carried out a few reforms, including the gradual elimination of domestic slavery, which had been a central feature of the Sokoto caliphate. They also provided Western education for some of Nigeria's elite; however, in the main Britain limited schooling as much as feasible.
Britain redirected almost all of Nigeria's trade away from Africa and toward itself, a move that undermined the northern region's large, centuries-old trade across the Sahara. Britain further changed the economy by introducing new crops and expanding old ones, such as oil palm, cotton, groundnuts, and cacao, almost all of which were sold for export. Iron and tin were also mined, and railroads were built to transport products. Because Britain required Nigerians to pay taxes in cash rather than goods, most Nigerians had little choice but to grow cash-yielding export crops or to migrate seasonally to areas where paying jobs could be found.
