- Causes of the War
The disintegration of the Oyo Empire and kingdom destroyed the pre-existing system of order and security in Yorubaland and created a situation whereby all centers of power, old and new, had to scramble to establish new systems and patterns that would guarantee order and security. Those efforts created conflicts and wars which the Yoruba people were not able to put an end to until European powers intervened and imposed their own system of order, security and peace. For two full centuries prior to the nineteenth century, the Oyo Empire had exercised powerful influences for peace in Yorubaland — both indirectly and directly. Indirectly, the Oyo kingdom, plus the Yoruba provinces in the Alaafin’s empire, amounted to a very substantial part of Yorubaland — about half of its land area and probably more than half of its total population.
