Answer:
The answer is Parliament.
The Puritans began to rebel against their English king when no Parliament was convened from 1629 to 1640.
Explanation:
Charles I from England governed without a Parliament in the period between 1629 to 1640, which resulted in riots and protests. The Parliament is the only way people have to speak to their king and also a limitation for the king's power. Without it, Charles I had the power centralized in his person. He tried to impose his ideas by force, and found resistance, not only the Catholics but especially the Puritans who saw in Charles I a threat for their liberty.
