The delegates elected George Washington of Virginia, former commanding general of the Continental Army in the late American Revolutionary War (1775–1783) and proponent of a stronger national government, to become President of the convention.
Once the convention began, however, most of the delegates – though not all – came to agree in general terms that the goal would be a new system of government, not simply a revised version of the Articles of Confederation.
The most contentious disputes involved the legislature, specifically the composition and election procedures for the Senate as the upper legislative house of a bicameral Congress, and whether proportional representation was to be defined by a state's geography or by its population.
Progress was slow until mid-July, when the Connecticut Compromise resolved enough lingering arguments for a draft written by the Committee of Detail to gain acceptance.
[6] The Second Continental Congress adopted the Declaration of Independence in 1776, and the 13 states created a permanent alliance to coordinate American efforts to win the Revolutionary War.
When Massachusetts and Pennsylvania placed reciprocal duties on British trade, neighboring states such as Connecticut and Delaware established free ports to gain an economic advantage.
This rebellion was led by a former Revolutionary War captain, Daniel Shays, a small farmer with tax debts, who had never received payment for his service in the Continental Army.
[23] Originally planned to begin on May 14, the convention had to be postponed when very few of the selected delegates were present on that day due to the difficulty of travel in the late 18th century.
[43] While waiting for the convention to formally begin, Madison sketched out his initial proposal, which became known as the Virginia Plan and reflected his views as a strong nationalist.
Quotas of contribution appealed to southern delegates because they would include slave property, but Rufus King of Massachusetts highlighted the impractical side of such a scheme.
Elbridge Gerry of Massachusetts and Roger Sherman of Connecticut feared the people were too easily misled by demagogues and that popular election could lead to mob rule and anarchy.
A few delegates such as Roger Sherman, Elbridge Gerry, and Pierce Butler opposed the direct election of the executive because they considered the people too easily manipulated.
To resolve this dispute, the Convention agreed that the House would elect the president if no candidate had an electoral college majority, but that each state delegation would vote as a bloc, rather than individually.
[92] William Paterson and other delegates from New Jersey, Connecticut, Maryland and New York created an alternative plan that consisted of several amendments to the Articles of Confederation.
The members of this "Grand Committee," as it has come to be known, included William Paterson of New Jersey, Robert Yates of New York, Luther Martin of Maryland, Gunning Bedford Jr. of Delaware, Oliver Ellsworth of Connecticut, Abraham Baldwin of Georgia, Elbridge Gerry of Massachusetts, George Mason of Virginia, William Davie of North Carolina, John Rutledge of South Carolina and Benjamin Franklin of Pennsylvania.
[109] During the debate on the census, South Carolina delegates Pierce Butler and Charles Cotesworth Pinckney sought to replace the three-fifths ratio with a full count of the slave population.
"[129]: 165 Randolph adopted two rules in preparing his initial outline: that the Constitution should only include essential principles, avoiding minor provisions that would change over time, and that it should be stated in simple and precise language.
[129]: 169 Examples of these details included the Speech and Debate Clause, which grants members of Congress immunity for comments made in their jobs, and the rules for organizing the House of Representatives and the Senate.
[129]: 165 The first major change, insisted on by Rutledge, was meant to sharply curtail the essentially unlimited powers to legislate "in all cases for the general interests of the Union" that the Convention only two weeks earlier had agreed to grant the Congress.
In Randolph's outline the committee replaced that language with a list of 18 specific "enumerated" powers, many adopted from the Articles of Confederation, that would strictly limit the Congress's authority to measures such as imposing taxes, making treaties, going to war, and establishing post offices.
It would also prohibit taxation of exports, and would require that any legislation concerning regulation of foreign commerce through tariffs or quotas (that is, any laws akin to England's "Navigation Acts") pass only with two-thirds majorities of both houses of Congress.
While much of the rest of the committee's report would be accepted without serious challenge on the Convention floor, these last three proposals provoked outrage from Northern delegates and slavery opponents.
One important change that did make it into the final version included the agreement between northern and southern delegates to empower Congress to end the slave trade starting in 1808.
Its members, such as Madison, were delegates who had shown a greater desire for compromise and were chosen for this reason as most in the Convention wanted to finish their work and go home.
[129]: 235 Some have argued that Randolph's attacks on the Constitution were motivated by political ambition, in particular his anticipation of possibly facing rival Patrick Henry in a future election.
The main objection of the three was the compromise that would allow Congress to pass "navigation acts" with a simple majority in exchange for strengthened slave provisions.
Upon Gerry's urging, the Convention added back the Virginia Plan's original method whereby Congress would propose amendments that the states would then ratify.
[129]: 229–30 They were William Samuel Johnson (Connecticut), Alexander Hamilton (New York), Gouverneur Morris (Pennsylvania), James Madison (Virginia), and Rufus King (Massachusetts).
At the time the document was signed, Franklin gave a persuasive speech involving an anecdote on a sun that was painted on the back of Washington's Chippendale chair.
[143]: 135 The entire agrarian economy of the South was based on slave labor, and the Southern delegates to the convention were unwilling to accept any proposal that they believed would threaten the institution.
