Held in Philadelphia, May 1908, the Pennsylvania Arbitration and Peace Conference set up an executive committee which founded the Pennsylvania Arbitration and Peace Society on December, 1909. Early in 1912, the Society became a branch of the American Peace Society, but as a result of a change in the latter's constitution in 1915 the Pennsylvania group withdrew. The Pennsylvania Arbitration and Peace Society reported branches in Pittsburgh, Titusville, Cumberland Valley, Harrisburg, and Philadelphia. Prominent leaders, all Quakers, included William I. Hull, Albert J. Linton, J. Augustus Cadwallader and Stanley R. Yarnall. The Society's active work ended during World War I. Yarnall reported in 1946 to the Peace Collection that the main body of the Society's papers were destroyed due to deterioration about 1921. The records in the Peace Collection may represent the extant information on this group.
