Created on September 24, 1788, from parts of Washington and Westmoreland Counties and named for the Allegheny River. General John Forbes named Pittsburgh, the county seat, in November 1758 in honor of William Pitt, a British statesman. It was incorporated as a borough on April 22, 1794 and as a city on March 18, 1816.
The conflict between the British and French over claims in this area was settled in 1758 when Gen. John Forbes and his British and American army forced the French to abandon Fort Duquesne, a post they had built in 1754. The British completed Fort Pitt in 1761. After the defeat of an Indian resurgence in 1763 and the end of a dispute for control with Virginia (1780), settlement swelled. This was an outfitting point for settlers who rafted down the Ohio River, and soon shipbuilding developed. A blast furnace erected by George Anshutz about 1792 began the long rise of the iron and steel industry. In 1845 a fire destroyed one-third of Pittsburgh, but in 1852 the Pennsylvania Railroad was opened to Philadelphia and in 1859 coke was first used in a blast furnace and cold rolling was invented. Pittsburgh was a major manufacturing center during the Civil War. Between 1874 and 1880 oil refineries, papermaking, and wood products industries were pushed to other locations because products that were made through high heat processes took over in Pittsburgh. From 1882 to 1901 the partnership of Henry Clay Frick and Andrew Carnegie achieved world leadership in steel. Violent labor strikes included the railroad strike of 1877, the Homestead Steel strike in 1892, and the SWOC 1936 strike. In 1901 Carnegie sold out to the new U. S. Steel Company. In 1920 the “value added by manufactures” figure for Pittsburgh’s industry began to decline, but from 1939 to 1954 steel experienced a second period of grandeur. In 1946 the “Pittsburgh Renaissance” city revivals (I and II) were first conceived. From about 1970 to the present, an era of deindustrialization has prevailed. However, an increase of 15 percent in the county’s figure for value added from manufactures between 1987 and 1992 suggests that the economy may have finally stabilized. The peak of Allegheny County’s population was 1,628,587 in 1960; the peak for Pittsburgh was 676,806 in 1950—and it is now only 369,879. The county has also been a major bituminous producer, blessed with the magnificent Pittsburgh coal vein. In the last five years subsurface mining has almost ceased. Farms still cover 9.2 percent of the land, and Allegheny is the ninth ranked mushroom-producing county.

Click Here to Search Pennsylvania Military Records! - Military and civil service records provide unique facts and insights into the lives of men and women who have served their country at home and abroad.
The uses and value of military records in genealogical research for ancestors who were veterans are obvious, but military records can also be important to re-searchers whose direct ancestors were not soldiers in any war. The fathers, grandfathers, brothers, and other close relatives of an ancestor may have served in a war, and their service or pension records could contain information that will assist in further identifying the family of primary interest. Due to the amount of genealogical information contained in some military pension files, they should never be overlooked during the research process. Those records not containing specific genealogical information are of historic value and should be included in any overall research design. A list of Wars fought on American.

The Repositories
in this section are Archives, Libraries, Museums, Genealogical
and Historical Societies. Many County Historical and Genealogical
Societies publish magazines and/or news letters on a monthly,
quarterly, bi-annual or annual basis. Contacting the local societies
should not be over looked. State Archives and Societies are
usually much larger and better organized with much larger archived
materials than their smaller county cousins but they can be
more generalized and over look the smaller details that local
societies tend to have. Libraries can also be a good place to
look for local information. Some libraries have a genealogy
section and may have some resources that are not located at
archives or societies. Also, take a special look at any museums
in the area. They sometimes have photos and items from years
gone by as well as information of a genealogical interest. All
these places are vitally important to the family genealogist
and must not be passed over.
