Question

Why did the colonists become hostile toward Great Britain

Answer 1

Well first we shall start with
1) After the French and Indian War the British put the Proclamation of 1763 that banned settlement west of the Appalachian mtns in order to prevent further Native-Settler conflict however the colonist viewed that they deserved the land after their participation in the F and I War.
2) The colonist were also angry because of their inferior treatment during the F and I War.
3) The British began to heavily tax the American colonies to help pay off their war debts(Tea Tax, Stamp Tax etc....)
4) Britain closely restricted colonial trade which forbid the colonists from trading with anyone except the British
5) The British also passed the Abominable Acts which were a set of laws that composed of the Quartering Act and others like it that the colonists viewed as invasion of privacy in the highest degree
