America was once a part of Britain. At first, British colonies occupied a large area of land in North America. Later, there were 13 colonies, which were granted a high degree of autonomy by the British government. These colonies also established their own autonomy system over time and copied it into the British parliamentary system. After a long period of development, the parliaments of the colonies gained the highest local rights, leaving the British representatives with no real power. 1756- 1763, the "seven-year war" broke out among European powers, and the North American colonies were also affected. After the war, Britain suffered huge losses a long time ago, and wanted to increase taxes in the colonies to make up for the losses during the war, which led to the dissatisfaction of the colonies and great resentment against the British government. The wealthy class in the colony shouted "No taxation without representation"

In this way, 1775, an armed rebellion broke out in the North American colonies under British rule. While the British were not paying attention, the rebels made Washington the commander-in-chief of the continental army and began to arm themselves. The representative body of the colony, the Continental Congress, adopted and published the Declaration of Independence, from which the United States was born.

In the eyes of the British government, the so-called United States is nothing more than a rebel regime, the continental congress convened by the rebels is also an illegal institution, and the Continental Army led by Washington is also a rebel of the British Empire. Therefore, the Declaration of Independence has no legitimacy, it is only a symbolic document of the founding of the United States and truly represents the legitimacy of the United States. It was signed in the Paris Treaty of 1783.

That is to say, before 1783, Washington and others were not Americans, but British rebels. After the signing of the Treaty of Paris, their rebel hats were removed, and they abandoned the status of British subjects and became legal Americans.
