A pilgrim is one who unertakes a pilgrimage, literally 'far afield'. This is traditionally a visit to a place of some religious or historic significance; often a considerable distance is traveled. Examples include a Muslim visiting Mecca or a Christian or Jew visiting Jerusalem. No religion has laid greater stress on the duty of a pilgrim than Islam in the Hajj. In the United States the word "Pilgrims" usually refers to the European settlers of New England, who celebrated the "First Thanksgiving" with the Native Americans in 1621.
