Answer :
The question should be "What began a period of great antagonism between the crown and the colonies?"
Answer and Explanation
After the French and Indian war, various colonies claimed the right to expand their boundaries as far as River Mississippi River due to their fast increasing population and the need for more land to enhance settlement.
The crown, typically the British government, wanted to restrict the settlements of the colonies to ensure that they had full royal control over existing settlements before the formation of new ones are allowed. The crown then attempted to forcefully put a stop to the western land claim of the colonies and eradicate expansion to the west. The colonies saw this as an encroachment on their rights to settle westwards.
