Many reasons existed as a rationale for the people of the 13 Colonies of England in the New World to wish to break away from the British empire and govern themselves. 

The short version of the reasons that the Colonies revolted are basically issues of taxes and religion:

• England issued the Stamp Tax against the colonists, requiring them to pay a tax for all printed documents.
• Next, England enacted the Townshend Acts, requiring colonists to pay taxes on glass, lead, paper, paint and tea. Colonists boycotted and some taxes were lifted.
• British soldiers and people of Boston who were protesting taxes began to fight and several Bostonians were killed in this, The Boston Massacre. Then England enacted another tea tax and The Sons of Liberty activist group in Boston hijacked a British tea ship and dumped its cargo into the sea at Boston Harbor. This is known as the Boston Tea Party in 1773.
• England immediately issued the Intolerable Acts, authorizing British officials to take all means necessary to control the Colonies. The Colonists formed the Continental Congress and began to revolt.
• Another reason for the revolt is that the Colonists did not want The Church of England to be their required church, thus freedom of religion was another issue.
