The Kingdom of Whydah was a kingdom on the coast of West Africa in what is now Benin. It was a major slave trading area which exported more than one million Africans to the United States, the Caribbean and Brazil before closing its trade in the 1860s. In 1700, it had a coastline of around 16 kilometres (10 mi); under King Haffon, this was expanded to 64 km (40 mi), and stretching 40 km (25 mi) inland.
