When the United States became independent, why did it choose to establish a central government in the form of confederation?

First, the United States became independent to oppose the British imposition of special taxes on the United States (at that time, it was a 13 British colony in North America).

Second, most of the early immigrants from North America came from Europe, and quite a few of them came to North America to escape religious persecution, so they had natural doubts about the central government.

Third, early immigrants thought that continental European countries were not democratic enough and the government power was too large.

Fourth, the choice of independent elders.

Fifth, at the time of its establishment, the Declaration of Independence was issued to prevent foreign colonial plunder, oppression and exploitation of people caused by concentration of rights.
