A Quaker who set aside his strong pacifist beliefs, Thomas Mifflin helped to organize Pennsylvania's military forces at the outset of the Revolutionary War and rose to the rank of major general in the Continental Army. This booklet on Mifflin is one in a series on Revolutionary War soldiers who also signed the U.S. Constitution, and it covers his business and political activities, his military service, and his public service to Pennsylvania as a delegate to the Constitutional Convention, state legislator, and governor. Personal data about Mifflin and a bibliographic essay of further readings are also included. (DJC)
