Who "Discovered" North Dakota? It Was Explored, Not Discovered — By French & British Fur Traders

North Dakota wasn't "discovered" — Indigenous peoples (Mandan, Hidatsa, Arikara, Dakota/Lakota, Chippewa, Assiniboine) lived there for 10,000+ years. The first Europeans to document the region were:

Early European Explorers (1700s)

• Pierre Gaultier de Varennes, sieur de La Vérendrye (French, 1738) — reached Mandan villages on Missouri River; claimed for France.
• David Thompson (British/Canadian, North West Company, 1797–1798) — mapped Red River, Pembina, Mouse River loops.
• Alexander Henry the Younger (NWC, 1800–1808) — detailed journals of Pembina River posts.

American Expeditions (Post-1803 Louisiana Purchase)

• Lewis & Clark (1804–1806) — wintered at Fort Mandan (near present Washburn, ND); mapped Missouri corridor.
• John Bradbury (1811) — botanist, Astor expedition.
• Stephen Long (1823) — Red River reconnaissance.

Fur Trade Posts (First Permanent Euro-American Presence)

• Pembina Post (1797, NWC) — oldest continuous settlement (now ND's oldest town).
• Fort Union Trading Post (1828, American Fur Co.) — upper Missouri hub.

Statehood

Dakota Territory (1861) → North Dakota admitted 2 Nov 1889 (39th/40th with South Dakota).

So: No "discoverer." First European visitors = French & British fur traders (1730s–1790s). Indigenous nations were already there.
