Why did the Antifederalist believe that the constition was a threat to liberty?

Antifederalists believed the Constitution posed a threat to liberty because they feared it created a strong central government that could infringe upon individual rights and state sovereignty. They argued that the absence of a Bill of Rights left citizens vulnerable to government overreach. Additionally, they were concerned that the Constitution favored the interests of the wealthy elite, undermining the democratic principles of representation and accountability. Ultimately, they believed that a powerful federal government would lead to tyranny and the erosion of personal freedoms.
