Fort Duquesne was a French fort established in 1754 at the confluence of the Allegheny and Monongahela rivers, where they form the Ohio River in present-day Pittsburgh, Pennsylvania. It was built to assert French control over the region during the early stages of the French and Indian War. The fort was named after Marquis Michel de Duquesne, the Governor-General of New France. In 1758, British forces captured Fort Duquesne, and it was subsequently destroyed. The British later built Fort Pitt on the same site, marking a significant shift in control over the area.
