Did the french establish trading post along Ohio river?

The French were among the first European settlers to establish trading posts along the Ohio River. The first French trading post in the Ohio River Valley was Fort Duquesne, which was built in 1754 at the confluence of the Allegheny and Monongahela rivers. Fort Duquesne was a key French stronghold in the Ohio Country and was the site of several battles during the French and Indian War. Other French trading posts along the Ohio River included Fort Vincennes, Fort Ouiatenon, and Fort de Chartres. These trading posts played an important role in the development of the Ohio River Valley and helped to establish France as a major power in North America.
