Pittsburgh (/ˈpɪtsbɜːrɡ/ PITS-burg) is a city in Allegheny County, Pennsylvania, United States, and its county seat. Located in southwestern Pennsylvania where the Allegheny and Monongahela Rivers meet to form the Ohio River, it had a population of 302,971 at the 2020 census, making it the second-most populous city in Pennsylvania. The Pittsburgh metropolitan area has over 2.43 million people, making it the largest in the Ohio Valley and Appalachia, the second-largest in Pennsylvania, and the 28th-largest in the U.S. The greater Pittsburgh–Weirton–Steubenville combined statistical area includes parts of Ohio and West Virginia.

Pittsburgh is known as "the Steel City" for its dominant role in the history of the U.S. steel industry. It developed as a vital link of the Atlantic coast and Midwest, as the mineral-rich Allegheny Mountains led to the region being contested by the French and British empires, Virginians, Whiskey Rebels, and Civil War raiders. For part of the 20th century, Pittsburgh was behind only New York City and Chicago in corporate headquarters employment; it had the most U.S. stockholders per capita. Deindustrialization in the late 20th century resulted in massive layoffs among blue-collar workers as steel and other heavy industries declined, coinciding with several Pittsburgh-based corporations moving out of the city. However, the city divested from steel and, since the 1990s, Pittsburgh has focused its energies on the healthcare, education, and technology industries.

Harrisburg (/ˈhærɪsbɜːrɡ/ HARR-iss-burg; Pennsylvania German: Harrisbarrig) is the capital city of the U.S. commonwealth of Pennsylvania. It is the ninth-most populous city in the state, with a population of 50,099 at the 2020 census, while the Harrisburg–Carlisle metropolitan statistical area has an estimated 615,000 residents and is the fourth-most populous metropolitan area in Pennsylvania. Harrisburg is situated on the east bank of the Susquehanna River 83 miles (134 km) southwest of Allentown and 107 miles (172 km) northwest of Philadelphia. It is officially incorporated as a third-class city and is the county seat of Dauphin County.

Harrisburg played a role in American history during the Westward Migration, the American Civil War, and the Industrial Revolution. During part of the 19th century, the building of the Pennsylvania Canal and later the Pennsylvania Railroad allowed Harrisburg to develop into one of the most industrialized cities in the Northeastern United States. In the mid- to late 20th century, the city's economic fortunes fluctuated with its major industries consisting of government, heavy manufacturing, agriculture, and food services. These economic fluctuations contributed to Harrisburg experiencing a decline of nearly half its population between 1950 and 2000. However, the region is seen as financially stable in part due to the high concentration of state and federal government agencies.
