Final answer:
Opposition to the U.S. Constitution ratification stemmed from fears of centralized power and loss of state rights, inspired by recent British rule. The Federalists argued for strong national governance for unity and economic reasons, while the Anti-Federalists resisted. The addition of the Bill of Rights helped assuage concerns and secure ratification.
Step-by-step explanation:
Many people opposed the ratification of the U.S. Constitution due to fears of an overpowering central government that would usurp the rights of states and individuals, drawing parallels to the recent British tyranny. Concerns included a potential to be burdened by heavy taxes, dragged into unnecessary wars, and the establishment of an elitist system favoring the wealthy.
The opposition, spearheaded by the Anti-Federalists, argued that local governance and individual freedoms could be at risk. The Federalists, in contrast, believed in a strong central government to maintain the union and promote economic growth, arguing their positions in the well-versed Federalist Papers. To mitigate some of these fears and garner wider support, a campaign was launched to sway public opinion, and the eventual addition of the Bill of Rights helped overcome much of the opposition.
