context_page_description: Pennsylvania was the site of key events and places related to the American Revolution. The state, and especially the city of Philadelphia, played a critical role in the American Revolution.
  Founding Father Robert Morris said, "You will consider Philadelphia, from its centrical situation, the extent of its commerce, the number of its artificers, manufactures and other circumstances, to be to the United States what the heart is to the human body in circulating the blood."
  The American Revolution included both the political and social development of the Thirteen Colonies of British America, and the Revolutionary War. John Adams wrote to Thomas Jefferson in 1815: "What do We mean by the Revolution? The War? That was no part of the Revolution. It was only an Effect and Consequence of it. The Revolution was in the Minds of the People, and this was effected, from 1760 to 1775, in the course of fifteen Years before a drop of blood was drawn at Lexington.
