Basseterre was founded in 1627 by the French, under Sieur Pierre Belain d'Esnambuc. It served as capital of the French colony of Saint-Christophe, which consisted of the northern and southern extremities of the island of St. Kitts (the centre was yielded to Britain). When Phillipe de Longviliers de Poincy was made the French governor of St. Kitts in 1639, the town turned into a large, successful port, commanding Eastern Caribbean trade and colonisation. De Poincy then quickly made Basseterre capital of the entire French West Indies colony, which included the islands of Guadeloupe and Martinique, and remained so until his death in 1660. The city was made capital of the entire island of St. Kitts in 1727, following French expulsion from the island and full British control.
