Answer:
The Colonists mentioned their complaints against king George in Complaints section o the Declaration of Independence. It contained 27 grievances against the action and decisions of King George Third. The grievances are similar to John Lock's works.
Historical documents like Bill of Rights 1689 and Magna Carta had already established the concept that King must not interfere with the rights of people. While in the views of colonists King George had done so by opposing the laws which were important for public good.
The declaration had four parts and it was in the third part that the complaints against King George was mentioned.
