What is one major reason why the Anti-Federalists opposed the Constitution?

The Anti-Federalists strongly opposed the Constitution primarily because they believed it lacked a Bill of Rights, which was seen as essential to protect individual liberties and limit governmental power. They feared that without explicit protections for rights such as freedom of speech, religion, and the press, the new national government could potentially infringe upon the rights of citizens. This concern stemmed from their experiences under British rule, where they faced repression and restrictions on their rights. The Anti-Federalists argued that the absence of a Bill of Rights made the Constitution too powerful and risky, as it did not offer adequate safeguards for personal freedoms. Their advocacy for a Bill of Rights ultimately led to the adoption of the first ten amendments to the Constitution shortly after its ratification, addressing those very concerns.
