The Declaration of Independence pointed out that all men are created equal, and the creator endowed them with certain inalienable rights, including the right to life, liberty and the pursuit of happiness.
Where there is oppression, there is resistance. People in the North American colonies could not live normally in the face of the complete deprivation and oppression of Britain. So they opposed slavery and advocated people's freedom and equal rights. And shouted the slogan "no taxation without representation" and embarked on the road of independence.
They want freedom, power, equality and independence. Therefore, on July 4th, 1776, Thomas Jefferson drafted and 13 other colonial representatives signed the Declaration of Independence, which initially declared the independence of the United States from Britain, representing the affirmation and practice of the concept of freedom and democracy.
Since then, the idea of freedom and equality has caused a dramatic impact in the colonies of various countries, so the wars of independence in the colonies of various countries have started one after another.
