abandon its colonial ambitions and withdraw its military garrisons from its French West African trading posts, leaving them in the care of resident merchants. The trading post at Grand Bassam in Ivory Coast was left in the care of a shipper from Marseille, Arthur Verdier, who in 1878 was named Resident of the Establishment of Ivory Coast.
In 1886, to support its claims of effective occupation, France again assumed direct control of its West African coastal trading posts and embarked on an accelerated program of exploration in the interior. In 1887 Lieutenant Louis Gustave Binger began a two-year journey that traversed parts of Ivory Coast's interior. By the end of the journey, he had concluded four treaties establishing French protectorates in Ivory Coast. Also in 1887, Verdier's agent, Marcel Treich-Laplène, negotiated five additional agreements that extended French influence from the headwaters of the Niger River Basin through Ivory Coast.

By the end of the 1880s, France had established what passed for control over the coastal regions of Ivory Coast, and in 1889 Britain recognized French sovereignty in the area. That same year, France named Treich-Laplène titular governor of the territory. In 1893 Ivory Coast was made a French colony, and then Captain Binger was appointed governor. Agreements with Liberia in 1892 and with Britain in 1893 determined the eastern and western boundaries of the colony, but the northern boundary was not fixed until 1947 because of efforts by the French government to attach parts of Upper Volta (present-day Burkina Faso) and French Sudan (present-day Mali) to Ivory Coast for economic and administrative reasons.
France's main goal was to stimulate the production of exports. Coffee, cocoa and palm oil crops were soon planted along the coast. Ivory Coast stood out as the only West African country with a sizeable population of settlers; elsewhere in West and Central
