Pittsburgh is located in southwest Pennsylvania at the confluence of the Allegheny River and the Monongahela River, which combine to form the Ohio River.[7] 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.[8] Pittsburgh is known both as "the Steel City" for its dominant role in the history of the U.S. steel industry, and as the "City of Bridges" for its 446 bridges.[9] 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.[10] Starting in the post-war era, Pittsburgh leaders began to strategically divest in manufacturing and invest instead in education, science, technology, health care, and art.[11] This led to deindustrialization in the 1970s and 1980s, resulting in massive layoffs among blue-collar workers as steel and other heavy industries declined, and thousands of downtown white-collar workers also losing jobs when several Pittsburgh-based companies moved out.[12]

After 1990, Pittsburgh has focused its energies on the healthcare, education, and technology industries.[13] Pittsburgh is home to large medical providers, including the University of Pittsburgh Medical Center, Allegheny Health Network, and 68 colleges and universities, including research and development leaders Carnegie Mellon University and the University of Pittsburgh.[14] The area has served as the federal agency headquarters for cyber defense, software engineering, robotics, energy research, and the nuclear navy.[15] In the private sector, Pittsburgh-based PNC is the nation's fifth-largest bank, and the city is home to eight Fortune 500 companies and seven of the largest 300 U.S. law firms. RAND Corporation, BNY Mellon, Nova, FedEx, Bayer, and the National Institute for Occupational Safety and Health have regional headquarters and offices that helped Pittsburgh become the sixth-best area for U.S. job growth.[16] Furthermore, the region is a hub for Leadership in Energy and Environmental Design and energy extraction.[17]

Pittsburgh's rich industrial history left the area with renowned cultural institutions, including the Carnegie Museums of Pittsburgh, Pittsburgh Parks Conservancy, Pittsburgh Zoo & Aquarium, Phipps Conservatory and Botanical Gardens, the National Aviary, and a diverse cultural district.[18] The city's major league professional sports teams include the Pittsburgh Steelers, Pittsburgh Penguins, and Pittsburgh Pirates. Pittsburgh is additionally where Jehovah's Witnesses traces its earliest origins, and was the host of the 2009 G20 Pittsburgh summit.
