The Patriotic Order Sons of America is an American patriotic fraternal organization that traces its origins to the anti-alien riots of the 1840s. Founded in 1847 in Philadelphia, the P.O.S. of A. once had "camps" (chapters) in well over 20 states. At its peak, there were more than 800 Camps in Pennsylvania alone.
