Step-by-step explanation:
The US Constitution was adopted in an environment of intense political struggle; its ratification was accompanied by fierce debate. There were widespread concerns about the possible usurpation of state rights and privileges by the federal authorities, and the emergence of an autocratic central government. Some opponents of the Constitution confirmed their doubts by referring to the ideas of Montesquieu. As it is known, he believed that democratic regimes are strong in small states, while large countries gravitate towards authoritarianism. Some followers of the famous French thinker even proposed to create not one, but three federations - the northern, central, and southern states. Another line of tension was between large and small states.
