Puritans came to the Americas to escape religious persecution, or the mistreatment or punishment of people because of their beliefs.
Two challenges the colonists had to overcome to be a successful colony, according to the video, could be:
1. Harsh climate and rugged environment - The colonists had to adapt to the new and challenging conditions of the wilderness, including harsh weather, rocky soil, and unfamiliar terrain.
2. Native American relations - The colonists had to navigate and establish relationships with the indigenous Native American tribes, which often involved conflicts, negotiations, and attempts at coexistence.
