Second Continental Congress - Philadelphia, Pennsylvania
We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.
King George III
The colonists opposed the way Britain ruled, so they came up with their own philosophies and laws. For example the idea that all men are born equal and that humans have innate rights just for being human, not because a king gave them to them.
That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed, — That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles...
It is natural for humans to form governments in order to protect and ensure these rights, and what gives the government its power is the compliance of those governed, as they want their rights to be protected.
However, if the government fails to suit the people, these have the right to revolt and replace it with one that does protect their innate rights and interests.
