In Germany the Brethren became known as Neue Täufer (New Baptists), in distinction from the older Anabaptist groups. In the United States they became popularly known as Dunkers, Dunkards or Tunkers, corruptions of the German verb tunken, to dip. Other religious groups related historically to the same Radical Pietist ferment as the Brethren are the Community of True Inspiration and the Moravians.
