What was the primary concern of the Anti-Federalists regarding the Constitution?

The primary concern of the Anti-Federalists regarding the Constitution was its establishment of a strong central government. They feared that the powers granted to the federal government were too broad and could lead to tyranny, undermining the authority and independence of individual states. The Anti-Federalists argued for a more decentralized system that preserved state sovereignty and allowed for local governance more in line with the needs and preferences of individual communities.

While the other options present points of contention, they were not the core concern that drove the Anti-Federalist movement. The establishment of a bicameral legislature, for instance, was seen as a way to balance representation, and the inclusion of a Bill of Rights was not initially part of the Constitution but subsequently became a significant point of advocacy to address some Anti-Federalist concerns. Ultimately, the crux of their opposition was centered on the fear of an overly powerful federal authority, which is why the creation of a strong central government stood out as the primary issue.
