The abbreviation for the state Pennsylvania is PA.
Pennsylvania is a northeastern U.S. state, bordered by Delaware, Maryland, West Virginia, Ohio, New York and New Jersey, as well as both Canada and Lake Erie. Pennsylvania is quite densely populated, with Philadelphia, the largest city, hosting over 1.5 million people. The state capital is Harrisburg, the namesake of the famed USS Harrisburg, a ship requisitioned from Britain which served through the First World War. The state is geographically varied, with the Appalachian Mountains running through the middle of the state along with a number of woodland parks. Pennsylvania is at the centre of the Dutch and British conquests of the Americas, and the state itself played a pivotal role in political movements which led to American independence, including in the convenance of Founding Fathers in 1774.
