From the 17th to the 19th century, political entities in the area included the Kingdom of Dahomey, the city-state of Porto-Novo, and other states to the north. This region was referred to as the Slave Coast of West Africa from the early 17th century due to the high number of people who were sold and trafficked during the Atlantic slave trade to the New World. France took over the territory in 1894, incorporating it into French West Africa as French Dahomey. In 1960, Dahomey gained full independence from France. As a sovereign state, Benin has had democratic governments, military coups, and military governments.
