Cast from their home country by religious intolerance, the Pilgrims' harrowing voyage to the New World was filled with hardships. But through it all they persisted, motivated by the promise of a better life in which they could gather and worship God in their own ways.

Besieged by illness and Indians and, many of them believed, witches, the Pilgrims eventually flourished, building up colonies and establishing their own rules for the practice of religion. Here is their dramatic story.
