The Massachusetts Peace Society (1815–1828) was an anti-war organization[1] in Boston, Massachusetts, established to "diffuse light on the subject of war, and to cultivate the principles and spirit of peace."[2] Founding officers included Thomas Dawes, William Phillips, Elisha Ticknor, Thomas Wallcut and Noah Worcester.[3] In 1828 the society "merged into the newly formed American Peace Society."[4][5]
