Like most colonial American leaders, John Dickinson considered himself an Englishman with all the ancient rights and privileges such citizenship conferred, and when those rights were abridged by the British Parliament and George III, he was among the first to don a uniform to defend the new nation. This booklet on Dickinson is one in a series on Revolutionary War soldiers who later signed the U.S. Constitution, and reviews his political activities prior to the Revolutionary War in Philadelphia (Pennsylvania), his military service, and his role as a representative from Delaware at the Constitutional Convention and in Delaware's ratification of the U.S. Constitution. Personal data about Dickinson and a bibliography essay of further readings are also included. (DJC)
