The French also established settlements in Maine. The first permanent French settlement in Maine was founded in 1604 on St. Croix Island. In 1613, the French established a trading post at Castine. The French also built forts at Pentagoet (Castine) and on the Kennebec River.
The French claimed all of the land between the St. Croix River and the Kennebec River as part of their territory in North America. They called this territory Acadia. The French and English competed for control of Acadia for many years. The French eventually lost control of Acadia in 1713 after the Treaty of Utrecht.
