In 1583, Sir Humphrey Gilbert, by the royal prerogative of Queen Elizabeth I, founded St. John's, Newfoundland, as the first North American English seasonal camp. In 1600, the French established their first seasonal trading post at Tadoussac along the Saint Lawrence. French explorer Samuel de Champlain arrived in 1603 and established the first permanent year-round European settlements at Port Royal (in 1605) and Quebec City (in 1608). Among the colonists of New France, ''Canadiens'' extensively settled the Saint Lawrence River valley and Acadians settled the present-day Maritimes, while fur traders and Catholic missionaries explored the Great Lakes, Hudson Bay, and the Mississippi watershed to Louisiana. The Beaver Wars broke out in the mid-17th century over control of the North American fur trade.
