The Pilgrims Society, founded on 16 July 1902[1] by Sir Harry Brittain KBE CMG, is a British-American society established, in the words of American diplomat Joseph Choate, 'to promote good-will, good-fellowship, and everlasting peace between the United States and Great Britain'. It is not to be confused with the Pilgrim Society of Plymouth, Massachusetts.
