Establishment of French Rule

Compared to neighbouring Ghana, Côte d'Ivoire suffered little from the slave trade, as European slaving and merchant ships preferred other areas along the coast with better harbours. The earliest recorded European voyage to West Africa was made by the Portuguese and took place in 1482. The first West African French settlement, Saint Louis, was founded in the mid-seventeenth century in Senegal while, at about the same time, the Dutch ceded to the French a settlement at Goree Island off Dakar. A French mission was established in 1637 Assinie near the border with the Gold Coast(now Ghana).

Assinie's survival was precarious, however. It was not until the mid-nineteenth century that the French were firmly established in Côte d'Ivoire. In 1843–1844, French admiral Bouët-Willaumez signed treaties with the kings of the Grand Bassam and Assinie regions, placing their territories under a French protectorate. French explorers, missionaries, trading companies, and soldiers gradually extended the area under French control inland from the lagoon region. Pacification was not accomplished until 1915.

Activity along the coast stimulated European interest in the interior, especially along the two great rivers, the Senegal and the Niger. Concerted French exploration of West Africa began in the mid-nineteenth century but moved slowly, based more on individual initiative than on government policy. In the 1840s, the French concluded a series of treaties with local West African rulers that enabled the French to build fortified posts along the Gulf of Guinea to serve as permanent trading centres.

France also wanted to maintain a presence in the region to stem the increasing influence of the British along the Gulf of Guinea coast. The French built naval bases to keep out non-French traders and began a systematic conquest of the interior. (They accomplished this only after a long war in the 1890s against Mandinka forces, mostly from Gambia. Guerrilla warfare by the Baoulé and other eastern groups continued until 1917).

The first posts in Côte d'Ivoire included one at Assinie and another at Grand Bassam, which became the colony's first capital. The treaties provided for French sovereignty within the posts, and for trading privileges in exchange for fees or coutumes paid annually to the local rulers for the use of the land. The arrangement was not entirely satisfactory to the French, because trade was limited and misunderstandings over treaty obligations often arose. Nevertheless, the French government maintained the treaties, hoping to expand trade.

The defeat of France in the Franco-Prussian War in 1871 and the subsequent annexation by Germany of the French province of Alsace Lorraine caused the French government to 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 Côte d'Ivoire was left in the care of a shipper from Marseille, Arthur Verdier, who in 1878 was named Resident of the Establishment of Côte d'Ivoire.

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 Côte d'Ivoire's interior. By the end of the journey, he had concluded four treaties establishing French protectorates in Côte d'Ivoire. 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 Côte d'Ivoire.
