Westmoreland County History

Created on February 26, 1773, from part of Bedford County and named for a county in England. Greensburg, the county seat after 1785, was incorporated as a borough on February 9, 1799 and as a city in 1928. It was named for General Nathanael Greene. The British and Indians burned Hannastown, the original county seat on July 13, 1782.

Ligonier and Bushy Run were posts licensed by the British Army in 1758, along the Forbes Road, before the full county area was acquired by Pennsylvania from the Indians in the New Purchase in 1768. At Bushy Run, in 1763, one of the few field engagements against Indians resulted in a British and colonial victory. Robert Hanna and Arthur St. Clair led the move to erect a Pennsylvania county to thwart the extension of Virginia's political control of the area. Rivalry with Virginia became violent in 1774-1775, but Virginia finally yielded its claim in 1779. This area was also involved in Dunmore's War and in Indian fighting during the Revolution. Hannastown, burnt by Indians in 1782, was not rebuilt because Greensburg was growing rapidly. The county's location on both the Forbes and Braddock Roads was vital to the rise of Pittsburgh. Railroads later followed, using approximately the same routes. Railroad yards grew at Monessen and Latrobe. Greensburg and Ligonier were farm products centers. The Connellsville Coke region, opened in the 1840s, led to the rise of Mount Pleasant and Scottdale. The valuable Pittsburgh Vein bituminous underlay the county. After coke making developed, there were booms in iron, steel, tinplate, aluminum, manufactured metal items, and glass. Silk, wool, paper, and rubber products followed. Natural gas was used by many industries. Ligonier continued to be a center for dairying and flour; auto parts were produced in Mount Pleasant, and tires in Jeannette. Since the 1960s, deindustrialization has been acute in the steel, aluminum, tinplating, and coke sectors. The peak of coal production occurred from 1925 to 1945; the county now is a minor coal producer from surface mines. In 1920 agriculture cash receipts were 11th in the state, and among these grain production was 8th in the state. Grain production was greatly reduced after WWII. In 1989, the county's farms are about 26th in total receipts among Pennsylvania counties, with strong meat, dairying, and mushroom production. Many small farms cover one-fourth of the land, and the county is a leader in eggs, oats, and alfalfa. Today, some steel is still produced and glass and metal products are important, but retail establishments are especially strong. Many residents are Pittsburgh workers.
