What was a major concern of the Anti-Federalists regarding the Constitution?

A significant concern of the Anti-Federalists regarding the Constitution was its lack of provisions for a Bill of Rights. The Anti-Federalists feared that without explicitly enumerating individual rights, the new federal government might infringe upon the liberties of the people. They believed that a Bill of Rights was essential to protect fundamental freedoms such as speech, religion, and the press. This advocacy for a Bill of Rights ultimately led to the first ten amendments being added to the Constitution, addressing these concerns by guaranteeing specific rights for citizens and limiting governmental power.

While the Anti-Federalists did express concerns about the balance of power between federal and state governments, the primary issue that mobilized them was the absence of guaranteed personal liberties in the original Constitution. The other options do not accurately reflect the most prominent worries of the Anti-Federalists, as they did not focus on promoting universal suffrage or restricting press freedoms in their main arguments against the Constitution.
