What did anti-Federalist propose to convince Massachusetts to ratify the constitution?

Anti-Federalists in Massachusetts proposed a series of amendments to the Constitution to address concerns over individual liberties and the potential for federal overreach. They argued for the inclusion of a Bill of Rights to protect personal freedoms and limit government power. Additionally, they emphasized the importance of state sovereignty and the need for a more balanced distribution of power between the federal and state governments. This combination of assurances helped sway some delegates to ultimately support ratification with the promise of future amendments.
