Why do you think that many otherwise contented colonists might have been ready after 1763 to resist britain’s efforts “to enclose its american colonists more snugly in its grip”?

The correct answer to this open question is the following.

Great Britain took some actions that angered the settlers in the American Colonies at the end of the French and Indian War,

England won the war and on October 7, 1763, it was King George III who signed the proclamation that annexed new territories to the English monarchy in America: Florida and Quebec. It was known as the Proclamation of 1763, and the negative part of this document was that prohibited American colonists to settle the territories west the Appalachians mountains. The proclamation prohibited to buy and settle Indian territory. It was just the British crown the only one that could purchase land. That made the colonists very angry at the British government and did not obey the order.

The English monarchy had many doubts about the loyalty of the colonists in America. So the King and the Parliament felt that the colonists had not shown enough support to the British during the French and Indian War, and the Proclamation of 1763 would serve as a punishment to let the Americans know that the King of England controlled the colonies.

the american revolution was by the middle and upper class, and the french was by the lower and middle class.
