Various European powers – Portugal, the Netherlands, and England – competed for trade in the area from the 15th century onward, until in 1677, France ended up in possession of what had become a minor slave trade departure point—the infamous island of Gorée next to modern Dakar. In 1758 the French settlement was captured by a British expedition as part of the Seven Years' War, but was later returned to France. It was only in the 1850s that the French, under the governor, Louis Faidherbe, began to expand their foothold onto the Senegalese mainland, at the expense of the native kingdoms.
