Pittsburgh. A city and port of entry of Alleghany Co., Pa. Pittsburgh was first settled in 1754, a stockade having been erected here which was occupied by the French as a trading-post, and given the name of Fort Duquesne. An English expedition against this fort under Gen. Braddock was defeated by the French and Indians, July 9, 1755. In 1758 another English expedition marched against this post, which was then regarded by the youthful Washington as the key of the West. An advanced detachment under Capt. Grant having encamped on what is still called Grant’s Hill, was attacked and defeated by a party of French and Indians from Fort Duquesne. But on the approach of Gen. Forbes, with a force of 6200 men, the disheartened garrison set fire to the fort and descended the Ohio River. The victorious troops, on entering, November 25, by general acclamation called the place Pittsburgh, in honor of William Pitt, then prime minister of England. The town of Pittsburgh was incorporated as a borough in 1804, and chartered as a city in 1816.
