1.2 The Constitutional Convention, Compromises, and Ratification Debates

Key Takeaways

  • The Great Compromise (Connecticut Compromise) reconciled large and small states by constructing a bicameral Congress: a House of Representatives based on population and a Senate with equal representation (two senators per state).
  • The Constitutional Convention incorporated profound moral and political compromises over slavery, notably the Three-Fifths Compromise for representation and taxation, and an explicit ban on federal interference with the transatlantic slave trade until 1808.
  • The Electoral College was established as a compromise balancing congressional selection, state legislative authority, and popular election of the president, while guarding against perceived voter passion.
  • James Madison's Federalist No. 10 argued that a large commercial republic with representative institutions controls the destructive effects of factions far more effectively than a direct, small-scale democracy.
  • Anti-Federalist critiques, exemplified by Brutus No. 1, warned that the Necessary and Proper and Supremacy Clauses would obliterate state sovereignty, resulting in a consolidated tyranny unless restrained by an explicit Bill of Rights.

The Constitutional Convention, Compromises, and Ratification Debates

In May 1787, fifty-five delegates convened at the Pennsylvania State House in Philadelphia. Although authorized by the Confederation Congress solely to revise the Articles of Confederation, the delegates—led by nationalists like James Madison, Alexander Hamilton, and James Wilson, with George Washington presiding—voted almost immediately to scrap the Articles entirely and construct an energetic, three-branch national republic.


1. Conflicting Plans: Virginia vs. New Jersey

The central dividing line during the opening weeks of the convention was legislative representation: should sovereign states be represented equally, or should representation reflect population?

The Virginia Plan (The Large-State Plan)

Drafted primarily by James Madison and introduced by Virginia Governor Edmund Randolph, the Virginia Plan sought to create a powerful national government with authority over individuals:

  • Bicameral Legislature: A two-house Congress where representation in both chambers was apportioned according to population or tax contributions.
  • Lower House: Directly elected by the people.
  • Upper House: Chosen by the lower house from nominations submitted by state legislatures.
  • Strong National Executive & Judiciary: Chosen by the national legislature.
  • Legislative Veto: Congress was empowered to veto state laws that conflicted with national statutes.
  • Advantage: Wealthy, populous states (Virginia, Pennsylvania, Massachusetts) would command dominant majorities in both chambers.

The New Jersey Plan (The Small-State Plan)

In direct opposition, William Paterson presented the New Jersey Plan on behalf of smaller states that feared political subjugation:

  • Unicameral Legislature: Maintained the Articles' framework where each state received one equal vote, irrespective of population.
  • Expanded National Powers: Granted Congress authority to levy import duties, enact stamp taxes, and regulate interstate and foreign commerce.
  • Plural Executive: An executive committee chosen by Congress, removable by a majority of state governors.
  • Limited Federal Judiciary: Appointed by the executive with narrow jurisdiction.
  • Supremacy of Federal Law: Explicitly stated that federal acts and treaties were the supreme law of the states.

2. The Grand Compromises

To preserve the Union and prevent delegates from walking out, the convention forged three historic compromises:

A. The Great (Connecticut) Compromise

Proposed by Roger Sherman and Oliver Ellsworth of Connecticut, the Great Compromise harmonized the Virginia and New Jersey frameworks:

  1. The House of Representatives: Lower house apportioned by population, directly elected by the people every two years, addressing the large states' demand for proportional representation. Crucially, all bills for raising revenue (taxation) must originate in the House (Article I, Section 7).
  2. The Senate: Upper house granting equal representation—each state receives two senators, addressing the small states' demand for parity. Senators served six-year staggered terms and were originally chosen by state legislatures (a safeguard against direct democracy that endured until the Seventeenth Amendment in 1913).

B. The Three-Fifths Compromise

A bitter sectional divide erupted over how enslaved human beings would be counted for legislative apportionment and direct taxation:

  • Southern Position: Southern delegates argued that enslaved people should be counted fully when determining a state's seats in the House of Representatives, but excluded when assessing direct federal taxes.
  • Northern Position: Northern delegates argued that because Southern law treated enslaved individuals as property without civil rights, they should not be counted for legislative representation, but must be fully counted for taxation.
  • The Resolution: Under the Three-Fifths Compromise (Article I, Section 2), each enslaved person was counted as three-fifths of a free person for both House seat allocation and direct taxation. This gave Southern slaveholding states an artificial 30% bonus in the House and Electoral College, profoundly shaping presidential elections and congressional legislation for seven decades.

C. Commerce and Slave Trade Compromise

Southern planters feared that a Northern congressional majority might enact export taxes on agricultural staples (tobacco, rice, cotton) or immediately abolish the transatlantic importation of enslaved Africans:

  • Export Clause: Article I, Section 9 explicitly forbade Congress from taxing exports from any state.
  • Slave Trade Moratorium: Congress was granted the power to regulate interstate and foreign commerce, but was barred from prohibiting "the Migration or Importation of such Persons as any of the States now existing shall think proper to admit" until the year 1808. (Congress outlawed the transatlantic slave trade on the earliest constitutionally permissible day: January 1, 1808).
  • Fugitive Slave Clause: Article IV, Section 2 mandated that enslaved individuals escaping to free states had to be returned to their enslavers upon claim.

D. The Electoral College Compromise

The framers deadlocked over the selection of the president:

  • Direct popular election was rejected due to fears of an uninformed public and sectional voting advantages.
  • Congressional selection was rejected because it would violate separation of powers and make the chief executive a subordinate tool of the legislature.
  • The Solution: The Electoral College (Article II, Section 1). Each state selects presidential electors equal to its total number of representatives and senators (House + Senate). Electors cast ballots for the presidency, blending federalism and indirect representation.

3. The Ratification Debate: Federalists vs. Anti-Federalists

Article VII of the Constitution established that ratification required approval by specially elected conventions in nine of the thirteen states. This triggered a fierce public debate between two opposing factions:

Federalists

Led by Alexander Hamilton, James Madison, and John Jay, the Federalists advocated for immediate ratification of the Constitution. They favored a robust, energetic national government capable of defending the border, maintaining internal order, establishing national credit, and fostering commerce. To persuade New York voters, Hamilton, Madison, and Jay published 85 essays under the pseudonym "Publius", known collectively as The Federalist Papers.

Anti-Federalists

Prominent Anti-Federalists included Patrick Henry, George Mason, Richard Henry Lee, and the author of the Brutus essays (widely attributed to New York judge Robert Yates). They argued that the proposed Constitution created an aristocratic, consolidated national leviathan that would swallow state sovereignty, centralize power in a distant capital, and degenerate into monarchical tyranny. Their primary objections included:

  1. The sweeping scope of the Necessary and Proper Clause and the Supremacy Clause.
  2. The national government's power to maintain a standing army during peacetime.
  3. The vast geographic size of the country, which precluded genuine republican representation.
  4. The conspicuous absence of a Bill of Rights guaranteeing fundamental liberties.

4. Landmark Ratification Texts: Federalist No. 10, Federalist No. 51, and Brutus No. 1

Federalist No. 10 (James Madison)

In Federalist No. 10, Madison addressed the Anti-Federalist charge that a republic could not succeed over a vast territory. He focused on the problem of factions—defined as a group of citizens, "whether amounting to a majority or a minority of the whole, who are united and actuated by some common impulse of passion, or of interest, adverse to the rights of other citizens, or to the permanent and aggregate interests of the community."

  • Curing Factions: Madison explained that there are two methods to cure the mischiefs of faction: removing its causes, or controlling its effects.
  • Causes Cannot Be Removed: Removing causes is impossible because it would require either destroying liberty (a remedy worse than the disease) or giving every citizen identical opinions and passions (an impossibility, since the unequal distribution of property is the most enduring source of faction).
  • Controlling Effects: Minority factions are easily controlled in a republic by regular majority voting. The grave danger is a majority faction that can sacrifice the public good and minority rights.
  • The Superiority of an Extended Republic: In a small, direct democracy, a majority faction easily unites and oppresses the minority. In an extended, large commercial republic:
    1. Power is delegated to elected representatives whose wisdom and patriotism refine and enlarge public views.
    2. The immense diversity of religious, geographic, and economic interests makes it difficult for a self-interested majority to discover its strength, communicate, and coordinate oppressive action.

Federalist No. 51 (James Madison)

In Federalist No. 51, Madison analyzed how the constitutional structure prevents tyranny from within:

  • Separation of Powers: The legislative, executive, and judicial branches must be kept largely independent.
  • Human Nature and Ambition: Institutional parchment barriers are insufficient to stop power grabs: "Ambition must be made to counteract ambition. The interest of the man must be connected with the constitutional rights of the place."
  • The Compound Republic (Double Security): In America, power is first divided between two distinct levels of government (state and federal—federalism), and then subdivided among distinct departments within each level (separation of powers). Hence, a "double security arises to the rights of the people."
  • Dividing the Legislature: Because the legislative authority naturally predominates in a republic, Madison justified dividing it into two distinct branches (House and Senate) with different modes of election and principles of representation.

Brutus No. 1 (Anti-Federalist)

Brutus No. 1 represents the most coherent Anti-Federalist indictment of the proposed Constitution:

  • Consolidated National Leviathan: Brutus argued that the combination of the Necessary and Proper Clause (Article I, Section 8) and the Supremacy Clause (Article VI) gave the national government boundless authority, reducing the states to mere administrative shells.
  • Unlimited Taxation and Armies: The federal power to tax without limit, coupled with the power to raise standing armies in peace, gave the national government all the tools needed to crush state resistance.
  • The Impossibility of a Large Republic: Citing Greek and Roman history and French philosopher Montesquieu, Brutus argued that genuine republics must be small and culturally homogeneous. In a vast nation spanning diverse climates, customs, and economies, representatives cannot know the minds of their constituents, elections will become corrupted, and rulers will govern through military force rather than the consent of the people.

5. The Bill of Rights Compromise

As ratification hung in the balance in crucial states like Massachusetts, Virginia, and New York, the Anti-Federalists' most persuasive weapon was the omission of a Bill of Rights.

Alexander Hamilton had argued in Federalist No. 84 that a Bill of Rights was not only unnecessary—because the proposed government possessed only delegated powers—but dangerous, asserting that declaring things which shall not be done would afford an excuse to claim powers not granted.

However, to secure ratification in contested conventions, Federalists pledged that the First Congress would immediately propose a series of constitutional amendments protecting fundamental civil liberties. True to his word, James Madison drafted twelve amendments in 1789, of which ten were ratified by the states in December 1791, becoming the Bill of Rights.
