Designation: National Historical Park
Location: Delaware, Pennsylvania
Famous as the First State to ratify the Constitution, Delaware was born out of a conflict among three world powers for dominance of the Delaware Valley. From this beginning, the region developed a distinct character that tolerated diversity in religion and national origin and valued independence.
For details and information, visit, http://www.nps.gov/frst/index.htm.
First State National Historical Park is made up of six individual sites throughout Delaware and southeastern Pennsylvania that explore early settlement through the ratification of the US Constitution. Please visit the individual pages for directions or hours of operation.

When Delaware declared its independence in 1776, it prompted a plethora of changes pertaining to its government and legal system. As the state grew and evolved, it reflected on crime and punishment in this new era. One crime that the new government reviewed was petit treason, which was treasonous acts committed against a person of authority other than the government.
Throughout its history, two Delaware women were tried for petit treason: Catherine Bevan in 1731 and Sarah Kirk in 1787. While their charges were the same, their punishments were not.
Join the New Castle Court House Museum and presenter Dana Niemeyer from the Delware Public Archives as they examine documents from the Delaware Public Archivesâ collections to discuss these women and the changing legal system of a new Delaware.
