The Massachusetts Compromise was the procedural bargain struck at the state’s 1788 ratifying convention that let delegates approve the U.S. Constitution outright while formally recommending a list of amendments for the new Congress to consider. On February 6, 1788, Massachusetts ratified by a vote of 187 to 168, becoming the sixth state to do so.1Mass.gov. The Ratification of the United States Constitution It mattered because the “ratify now, amend later” formula broke a deadlock that could have sunk the Constitution, gave the remaining states a workable template, and set the political stage for the Bill of Rights two years later.
What the Compromise Actually Did
The mechanism was straightforward. Massachusetts would ratify the Constitution without conditions, and the same resolution would attach a set of recommended amendments. The preamble to the recommendations stated that “certain amendments and alterations in the said Constitution would remove the fears and quiet the apprehensions of many of the good people of this Commonwealth.”2Avalon Project. Ratification of the Constitution by the State of Massachusetts
That structure mattered legally. The Philadelphia Convention had refused to allow conditional ratification, fearing that if each state could attach binding demands the result would be “confusion and contrariety” and the project would collapse. State conventions were meant to consider the document “in toto,” approve or reject, nothing in between.3The Founders’ Constitution. Article 7, Section 2 The Massachusetts approach threaded that needle. The recommendations carried no legal force, so the ratification itself was clean and unconditional. But the convention’s formal endorsement of specific changes created a strong political expectation that the First Congress would act on them.
Federalists got their ratification. Anti-Federalists got a public commitment to reform. Neither side had to abandon its core position.
Why the Convention Was Stuck
The convention opened on January 9, 1788, with roughly 364 delegates in Boston and an Anti-Federalist majority. Two objections dominated the early debate: the Constitution contained no bill of rights, and it gave Congress the power to tax citizens directly, bypassing state legislatures.
The tax question hit hardest in the farming communities that had lived through Shays’ Rebellion the year before. Rural delegates feared a federal poll tax would fall as heavily on the poor as on the wealthy, and they distrusted the “lawyers, and men of learning, and moneyed men” they expected to fill Congress.4Constitution Society. Debates in the Convention of the Commonwealth of Massachusetts, on the Adoption of the Federal Constitution Federalists answered that the Articles of Confederation had already proven too weak: Congress could not raise revenue, could not maintain an army, and could not respond to uprisings like the one that had recently swept western Massachusetts.5George Washington’s Mount Vernon. Shays’ Rebellion Neither argument was moving enough votes to matter.
Two figures unlocked the stalemate. Governor John Hancock, elected president of the convention, had stayed away from the sessions citing gout, waiting to see which side would prevail. Federalist leaders, including Rufus King, negotiated for his support and promised unified backing for his future political ambitions.6Center for the Study of the American Constitution. The Role of John Hancock in the Massachusetts Convention On January 30, Hancock appeared at the convention and introduced what he called a “conciliatory proposition.”
Samuel Adams was the second key. Adams was suspicious of any government without explicit protections for individual liberty, and rural delegates trusted his judgment. Pressure came from Boston’s mechanics and tradesmen, many of them former Sons of Liberty, who met at the Green Dragon Tavern and unanimously endorsed a pro-ratification resolution drafted by Paul Revere. Adams, whose political base was exactly this constituency, ultimately spoke in support of Hancock’s plan.7Massachusetts Historical Society.

The Nine Recommended Amendments
The convention attached nine specific proposals to its ratification. They tracked the anxieties that had filled the debate:8Teaching American History. Massachusetts Ratifies 187-168 With 9 Proposed Amendments
- All powers not expressly delegated to Congress would remain with the states.
- Congress would provide one representative for every 30,000 people until the total reached 200 members.
- Congress would not interfere with state-run federal elections unless a state failed to act or adopted rules that undermined fair representation.
- Congress could not levy direct taxes until it first requested that states collect their share, and only if import duties and excise taxes fell short.
- Congress could not create merchant companies with exclusive trading privileges.
- No person could be tried for a serious crime carrying infamous punishment or death without a grand jury indictment, except in military cases.
- Federal courts could not hear disputes between citizens of different states unless the amount at stake reached $1,500, or $3,000 for cases heard by the Supreme Court.
- Either party in a civil lawsuit between citizens of different states could demand a jury trial on factual questions.
- No federal officeholder could accept a title of nobility or any office from a foreign king or prince.
Some of these proposals shaped the Bill of Rights almost word for word. The reserved-powers language became the Tenth Amendment. The grand jury requirement appeared in the Fifth. The demand for civil jury trials was echoed in the Seventh. Others, like the ban on commercial monopolies and the limits on direct taxation, reflected concerns specific to the 1780s and did not survive into the final amendments.
How the Template Spread to Other States
The compromise had immediate national consequences because other conventions were just as divided. New Hampshire opened deadlocked at 52 to 52. After three days of debate, five delegates changed their votes on the Massachusetts model, and New Hampshire ratified on June 21, 1788, by 57 to 47. That made it the crucial ninth state, the number needed to put the Constitution into effect.9Teaching American History. The Six Stages of Ratification
Virginia followed on June 26, ratifying 89 to 79 after rejecting an attempt to make amendments a binding condition and instead adopting the Massachusetts approach of recommending “subsequent amendments” to the First Congress. New York held out until July 26 and then ratified 30 to 27, attaching 25 proposed bill-of-rights items and 31 further recommended amendments.9Teaching American History. The Six Stages of Ratification In each state, narrow majorities formed only because ratification came coupled with a credible promise of reform.
The Path to the Bill of Rights
The compromise carried an implicit promise, and James Madison delivered on it. Madison had originally argued a bill of rights was unnecessary, but the pressure from Massachusetts and other conventions changed the political calculation.10National Archives. The Bill of Rights: How Did it Happen? After winning a seat in the First Congress, he drafted what became the Bill of Rights using the amendments submitted by the state conventions.
Madison made a deliberate selection. The state proposals fell into two categories: guarantees of individual rights, and structural changes that would have weakened the federal government’s core operations. He drew from the first category and set the second aside.11Center for the Study of the American Constitution. The Role of James Madison in the Creation of the Bill of Rights The ten amendments ratified in 1791 answered the Anti-Federalist demand for explicit protections without dismantling the constitutional framework the Federalists had built.
That outcome traces directly back to the Boston convention. Massachusetts did not invent the Bill of Rights, but its compromise created the political mechanism through which the Bill of Rights became possible. A “yes” vote paired with a formal list of demanded changes turned ratification from a zero-sum choice into a two-step process, and every subsequent convention that used the same formula was, in effect, endorsing the deal Massachusetts had written first.
