King Charles I inherited from his father, James I (also referred to as James VI of Scotland), a divided kingdom when it came to matters of religion. England was also the ruler of Presbyterian Scotland and the largely Catholic Ireland. Closer to home, there were many dissenting groups; Brownists, Diggers, Levellers, and Enthusiasts just to name a few.
The British colonization of North America, not unlike most other colonizations, centered around the prospect of wealth and interest in evangelization. It is no surprise then that many of the conflicts that occurred in the British colonies started out of the friction this caused between the Native Americans and the colonists.
