Allegheny County was officially created on September 24, 1788 from parts of Washington and Westmoreland Counties. It was formed due to pressure from settlers living in the area around Pittsburgh, which became the county seat in 1791. The county originally extended all the way to the shores of Lake Erie and became the "mother county" for most of what is now northwestern Pennsylvania. By 1800, the county's current borders were set.

In the 1790s, a whiskey excise tax was imposed by the United States Federal Government. This started the so-called Whiskey Rebellion when the farmers who depended on whiskey income refused to pay and drove off a local town's marshal. After many demonstrations by farmers, President George Washington arrived with troops to stop the rebellion. The area developed rapidly throughout the 19th to become the center of steel production in the nation. Pittsburgh would later be labelled as the "Steel Capital of the World."  --Wikipedia.com
