The colonists were really fed up with the ridiculous rules and unfair taxes the British were instilling. The colonists threatened the British government by saying "if you don't stop with these unbelievable taxes, we will remove ourselves from your country with or without your consent."
The British did not listen so the colonists declared war. Some years later near the end of the war, the colonists were the clear winner. They wrote the Declaration of Independence to the British King, King Henry the VIII {not 100% sure on the name} and he signed it.
The British restriction of trade could be considered a violation of natural rights because 'Restrictions interfered with individuals' pursuit of economic self-interest'.
