Many of the European Christian settlers who colonized North America were fleeing religious persecution in their home countries in order to begin anew in the New World. About a century after the first Pilgrims arrived here, according to PBS, another Christian group arrived. However, unlike the original (as well as later) settlers, this group, originally from Switzerland, did not fully integrate itself into the new society. Instead, they kept to themselves and retreated inward into their own communities, eschewing outside influences and focusing solely on simple living and the betterment of their own micro-society. Today we know this Christian group as the Amish.
