In 1908 Gabriel Angoulvant was appointed governor of Ivory Coast. Angoulvant, who had little prior experience in Africa, believed that the development of Ivory Coast could proceed only after the forceful conquest, or so-called pacification, of the colony. He thus embarked on a vigorous campaign, sending military expeditions into the hinterland to quell resistance. As a result of these expeditions, local rulers were compelled to obey existing antislavery laws, supply porters and food to the French forces, and ensure the protection of French trade and personnel. In return, the French agreed to leave local customs intact and specifically promised not to intervene in the selection of rulers. But the French often disregarded their side of the agreement, deporting or interring rulers regarded as instigators of revolt. They also regrouped villages and established a uniform administration throughout most of the colony. Finally, they replaced the "coutume" with an allowance based on performance.
