Pennsylvania
Pennsylvania, one of the Mid-Atlantic states and one of the 13 original founding states, is called “The Keystone State”. It made key contributions to the United States’ economic, social, and political development. It’s known for manufacturing steel, production of Hershey (making it the Chocolate Capital of the US), the home to the first computer, and where the first American Flag was created in (thanks to Betsy Ross).
The US history is quite present in Pennsylvania, where the Declaration of Independence was signed in, specifically in Philadelphia in 1776. Did you know that Philadelphia, Pennsylvania was once the US capital?
