1. The Declaration of Independence opposed the feudal hierarchy and the absolute power of the monarch. The famous saying in the declaration: "All men are created equal." It is not appropriate to translate it into "all men are created equal". Jefferson was very critical of his words. In the face of such an important campaign, he will think carefully about every word and will never leave it at that. There is a "born" in English, so why didn't Jefferson use it? Probably because people born are not all equal under the influence of family, environment and other factors, but people created by the creator are equal. From such a small detail, we can see how much Jefferson longed for people to understand the declaration accurately. The "equality" here is anti-feudalism and hierarchical equality, that is, the equality of all people in natural human rights.

Second, Jefferson stripped the essence of Locke's thought from the unconvincing and obscure argument, which was highly summarized and refined, catchy and widely circulated. The revolution was first completed in the minds of Americans, and the rest came naturally. The Declaration of Independence provided a natural environment for American liberalism and laid a foundation for its development in the United States.

Third, the Declaration of Independence turned American common sense and creed into a revolutionary declaration, which provided a theoretical basis for the War of Independence. And the victory of the war of independence turned it into reality. European seeds blossom and bear fruit in the United States and thrive. As we all know, it is an arduous process to turn an ideological theory into reality, and what is needed in the process is self-denial and renewal.

Significance: The Declaration of Independence established the principles of bourgeois revolution and human rights in the form of a political program for the first time. Marx called it the first declaration of human rights. To some extent, the Declaration reflects the political aspirations of the colonial people in North America for freedom and independence. On the other hand, due to the pressure of plantation slave owners, the declaration did not declare the abolition of slavery, and natural human rights did not include blacks and Indians, which exposed the incompleteness of American bourgeois revolution and the limitations of human rights. The publication of the Declaration of Independence played an important role in mobilizing the masses to launch the war of independence. The declaration had a positive impact on the bourgeois revolution in European countries, especially on the French Revolution and its declaration of human rights. At the same time, North America 13 colony declared its independence from Britain. The United States of America was born.
