From the 16th to the 18th centuries, French explorers mapped vast areas of North America. Major regions they explored include:
Jacques Cartier began French exploration of Canada in 1534–1535. Samuel de Champlain founded Quebec City in 1608 and Montreal in 1642, mapped the Great Lakes, and established trading posts.
René-Robert Cavelier, Sieur de La Salle, explored the Mississippi River in the late 17th century, claiming the entire basin for France and naming it Louisiana. New Orleans was founded as a major port in 1718.
French traders and explorers navigated the Mississippi, establishing forts and settlements at Kaskaskia, Cahokia, and Vincennes.
French fur traders followed rivers and Native American trade routes into the Great Plains and Rockies, setting up posts along the Missouri River and in the Black Hills.
The French founded Mobile, Alabama, in 1702 and established settlements and trading posts across present-day Alabama, Mississippi, and Texas.
Overall, French exploration laid the groundwork for colonization, trade networks, and cultural exchange across the continent.
