First of all, most colonists were from Britain. This connected links to the British, so the British could come into America when they wanted. King George the Third implemented many acts into our Nation which angered the colonists. The more acts the King placed on America, the more opposed the colonists got. Then there was the French-Indian War which killed plenty of our men because of how cocky the British were.

The proclamation of 1763 forbade colonists from crossing the appalachian mountains, because Great Britain decided that if the colonists took too much land, the Indians would attack, and Britain did not want to be at war with the Indians, especially after the costly fight with France, which left their coffers (money) empty
