The colonists rebelled against England for several reasons. The colonists were upset with the tax laws that were passed. The colonists believed they should have a say about any tax law that would affect them. This is a basic right English citizens have. However, the colonists had no representatives in Parliament who could speak about or vote on proposed taxes. Thus, they resented taxes that came with the Stamp Act or Townshend Acts.
The colonists also believed the British were restricting their freedom. When the Proclamation of 1763 was passed, the colonists were not allowed to move west of the Appalachian Mountains. The colonists wanted to move to this area where they would be able to get land. Land ownership was very important to the colonists. Thus, they opposed this law. They also opposed the Quartering Act that required them to provide places for soldiers, who were enforcing this law, to live.
The colonists were concerned about the violence that occurred with the Boston Massacre and the harsh response by the British to the Boston Tea Party. When fighting occurred at Lexington and Concord in April 1775, many colonists felt going to war was the only option to resolve the differences that existed between the colonists and the British.
