What are the reasons for the conflict between the inhabitants of the colonies and the English crown.

There were such reasons for the outbreak of the War of Independence between the American colonies and Britain:
1) The permanent presence of the British military forces;
2) Significant customs taxes and restrictions that were imposed on the trade of the colonies;
3) At that time, the colonies were able to reach a level of development when they could create their own state and not depend on anyone.
Ultimately, a war broke out between the parties, which ended in the victory of the American colonies.
