The county originally included the present-day counties of Fayette, Washington, Greene, and parts of Beaver, Allegheny, Indiana, and Armstrong counties.
On December 20, 1785, Joseph Ross of Westmoreland County was sentenced to death for the crime of sodomy. This is the only known execution for sodomy to take place in Pennsylvania's history.[4]

Political history
The Democratic Party historically dominated county-level politics between the New Deal realignment and the turn of the century; however, Westmoreland has trended Republican at the national and statewide levels in the 21st century (in direct lockstep with most other Appalachian counties).
In 2000, Republican George W. Bush became the first Republican to carry the county since 1972. Republicans have won the county in every election since, increasing the margin of victory in every successive election until 2020. Democratic Governor Ed Rendell lost Westmoreland in 2002 and 2006. In 2004, Republican Bob Regola flipped the 39th Senate district by beating out incumbent Allen Kukovich. Then in 2008, Republican Tim Krieger picked up the 57th House district left open by the retirement of Democratic state representative Tom Tangretti. Kim Ward also held 39th Senate district for the GOP the seat Bob Regola flipped four years earlier.
In 2010, both Pat Toomey and Tom Corbett won Westmoreland in their statewide bids. Also, the GOP gained control of two more State House districts, the 54th with Eli Evankovich and the 56th with George Dunbar. In 2011, the Republican Party swept all county row offices.[24] A Democratic resurgence in 2015 gave that party a majority of the county commissioners. However, in the 2019 elections, Democratic elected officials lost that majority and carried only one row office. In 2020, the County Sheriff, who was the lone Democrat who won a row office in 2019, switched party affiliations from Democratic to Republican. In 2021 Republicans carried all of the row offices including defeating the incumbent District Attorney and County Coroner, following the 2021 election the minority County Commissioner was the only Democrat to hold Countywide office. In 2023, Republicans retained their majority on the Board of Commissioners and held every row office.
As of 2020, the only majority-Democratic cities within the county are Arnold and Monessen.[25] That being said, local Democrats running statewide sometimes win additional cities and boroughs. For example, in the 2022 Gubernatorial race, the cities of Greensburg, New Kensington, Latrobe, and Jeannette all voted for Democrat Josh Shapiro over Republican Doug Mastriano despite voting Republican in the 2020 Presidential election.[26]

County commissioners
Westmoreland County is administered by a three-member publicly elected commission. Each commissioner serves in four-year terms. Elections occur in the odd-numbered years that precede U.S. presidential elections. All three Commissioners are chosen in the same election, and voters may vote for no more than two candidates. By state law, the commission must include a minority party to ensure a political split on the commission. The Commissioners are responsible for the management of the county's fiscal and administrative functions.

Economy
Coal mining became a major industry in the county after the Civil War, followed by the expansion of iron, steel, and glass manufacturing. The 600-acre coke works for the Isabella Furnace were built in Cokeville (then Coketown) in the Spring of 1872.[34][35] At one point, company "coal patches" (towns built for miners) represented about one-third of the county's settlements.[36] A major strike by coal miners represented by the United Mine Workers of America took place in 1910–1911. Sixteen people were killed in the strike.[37]
In 2020, the top industries in the county were health care and social services (16.3% of jobs), manufacturing (13.8%), and retail trade (13.7%).[38] Mining comprised less than 1% of the jobs in the county. Westmoreland County is now believed to contain over 100 abandoned mines.[39][40]
Volkswagen's Westmoreland plant near New Stanton in Westmoreland County was the first foreign-owned factory mass-producing automobiles in the U.S. It operated from 1978 to 1988.
