After 1630, Puritans began pouring in and setting up colonies around present-day Boston. These new colonists were only barely tolerant of other Christian denominations and viewed the natives as savages and heathens with little interest in friendship or trade. In 1637, they destroyed the Pequot and then in 1643 helped the Mohegan defeat the Narraganset. For the next thirty-five years, new settlers flowed in and pushed the natives westward. These new settlers had only contempt for the natives and saw them as standing in the way of progress. In addition to their aggression, the new settlers brought alcoholism and new epidemics to the natives again and again devastating populations.
