Province of Quebec in 1774. Like the French, the British were interested in little but the fur trade. One notable event in the fur trading industry in Wisconsin occurred in 1791, when two free African Americans set up a fur trading post among the Menominee at present day Marinette. The first permanent settlers, mostly French Canadians, some Anglo-New Englanders and a few African American freedmen, arrived in Wisconsin while it was under British control. Charles Michel de Langlade is generally recognized as the first settler, establishing a trading post at Green Bay in 1745, and moving there permanently in 1764. In 1766 the Royal Governor of the new territory, Robert Rogers, engaged Jonathan Carver to explore and map the newly acquired territories for the Crown, and to search for a possible Northwest Passage. Carver left Fort Michilimackinac that spring and spent the next three years exploring and mapping what is now Wisconsin and parts of Minnesota. Settlement began at Prairie du Chien around 1781. The French residents at the trading post in what is now Green Bay, referred to the town as "La Bey", however British fur traders referred to it as "Green Bay", because the water and the shore assumed green tints in early spring. The old French title was gradually dropped, and the British name of "Green Bay" eventually stuck. The region coming under British rule had virtually no adverse effect on the French residents as the British needed the cooperation of the French fur traders and the French fur traders needed the goodwill of the British. During the French occupation of the region licenses for fur trading had been issued scarcely and only to select groups of traders, whereas the British, in an effort to make as much money as possible from the region, issued licenses for fur trading freely, both to British and French residents. The fur trade in what is now Wisconsin reached its height under British rule, and the first self-sustaining farms in the state were established at this time as well. From 1763 to 1780, Green Bay was a prosperous community which produced its own foodstuff, built graceful cottages and held dances and festivities. The territorial period The United States acquired Wisconsin in the Treaty of Paris (1783). Massachusetts claimed the territory east of the Mississippi River between the present-day Wisconsin-Illinois border and present-day La Crosse, Wisconsin. Virginia claimed the territory north of
