The Constitutional Convention
Essential terms, compromises, and questions
Central question: How did negotiation produce a stronger national government while limiting its power—and whose interests did the resulting compromises protect?
HOW TO USE THIS GUIDE: Open the concept panels, read the constitutional provisions, and write your own answers before revealing the explanations. Prepare to explain the disagreement, the settlement, and its effect on power. This is a study guide; responses are not collected here.
AP ESSENTIAL · CED Topic 1.5: Know the Great Compromise, Electoral College, Three-Fifths Compromise, slave-importation provision, and assurances about a Bill of Rights. Explain Article V and continuing disagreements about national authority, state authority, and individual rights. The CED specifically identifies government surveillance after 9/11 and the government’s role in public education as applications.
Current CED, effective fall 2026: printed pp. 45–46.
HELPFUL CONTEXT / OPTIONAL DETAIL: The final gold section supplies background about competing plans, delegates, and the meeting. Those details support understanding; they are not a separate list of facts to memorize for Topic 1.5. The labels in this guide describe study priorities, not predictions of particular exam questions.

1 · From the Articles to a new Constitution
Delegates met in Philadelphia in 1787 amid concerns about the Articles of Confederation. They produced a new framework that expanded national authority. The central challenge was to make government capable of acting without allowing it to become tyrannical.
Keep these stages separate| Stage | What happened | Why the distinction matters |
|---|
| Convention · 1787 | Delegates negotiated the structure and signed the proposed Constitution. | Drafting and signing did not, by themselves, ratify the Constitution. |
|---|
| Ratification · began in 1787 | State conventions considered the proposal. Article VII set a threshold of nine states to establish the Constitution among ratifying states. | Ratification meant approval by state conventions; it was a different process from amending the Articles. |
|---|
| New government · 1789 | The new constitutional government began operating. | The Constitution expanded federal power while dividing authority among institutions. |
|---|
| Bill of Rights · 1791 | The states ratified the first ten amendments. | Promises to pursue rights amendments helped secure support during ratification; the Convention did not attach the Bill of Rights to its original document. |

CONNECT TO TOPIC 1.4: Under the Articles, Congress depended heavily on the states for money and cooperation. The Constitution supplied independent taxing authority, power over interstate commerce, a separate executive, and a national judiciary. Greater capacity made safeguards against concentrated power more consequential.
2 · AP essential: five settlements to explain
For each settlement, identify who disagreed, what they accepted, and how the arrangement distributed power.
01 · Great / Connecticut CompromisePopulation in the House; equal state representation in the Senate.
The disagreement: States with larger populations wanted representation to reflect population. Smaller states feared domination and defended equal state representation.
The settlement: A bicameral Congress. House representation reflected population; each state received two senators.
Effect on power: Larger populations produced more House seats, while the Senate protected equal state representation. Both chambers had to agree to pass legislation.
AP distinction: The compromise did not give every state equal representation in both chambers. “Bicameral” describes two legislative chambers; “separation of powers” describes the division among branches.
Question: Why could a small state accept this arrangement even though it would have fewer House seats?
Open the explanation
Its two senators gave it the same Senate representation as any larger state. Because legislation required both chambers, populous states could not legislate through the House alone.
Source: U.S. Senate, A Great Compromise
02 · Electoral CollegeA state-based system for selecting the president.
The disagreement: Delegates considered different ways to select the president, including selection by Congress and direct popular election.
The settlement: Electors appointed through each state would choose the president. Each state’s number of electors equaled its House seats plus its two senators.
Effect on power: Presidential selection combined population and state representation. The system reduced reliance on Congress for ordinary presidential selection while avoiding a single nationwide popular vote.
AP distinction: Electors are not members of Congress. The Constitution did not require states to use a winner-take-all system. Congress does have a contingent-election role when no candidate wins the required electoral majority.
Question: A state has eight representatives. How many electors does it receive, and what does that reveal about the compromise?
Open the explanation
Ten: eight representatives plus two senators. Population affects the House portion, while every state receives the same two-elector Senate component.
Source: Constitution, Article II, Section 1
03 · Three-Fifths CompromiseA rule for apportionment that strengthened slaveholding interests.
The disagreement: Delegates disputed whether, and how, to count enslaved people when allocating representation and direct taxes among states. Counting more enslaved people increased a slaveholding state’s representation, even though those people could not vote.
The settlement: The apportionment formula counted three-fifths of the enslaved population for House representation and direct taxation.
Effect on power: Compared with excluding enslaved people from the count, the formula increased slaveholding states’ House seats and, through House seats, their Electoral College strength. It entrenched slaveholders’ political influence without giving enslaved people political rights.
AP distinction: This was a population-counting formula, not a grant of three-fifths of a vote or three-fifths of citizenship. The taxation component concerned apportioning direct taxes among states.
Question: Why could a representation formula benefit slaveholders while denying political participation to the people being counted?
Open the explanation
The formula increased their state’s representation without allowing enslaved people to choose those representatives. Representation allocated to a state and voting rights for individuals are different matters.
Source: Constitution, original Article I, Section 2
04 · Protection of slave importation until 1808The restriction concerned importation, not an end date for slavery.
The disagreement: Delegates disagreed about whether the national government should be able to prohibit the importation of enslaved people. Delegates defending the trade demanded protection for it.
The settlement: Article I, Section 9 barred Congress from prohibiting the importation covered by the provision before 1808.
Effect on power: The provision delayed congressional action against the international slave trade and protected the interests of states that continued to permit importation.
AP distinction: The Constitution did not abolish slavery in 1808 or require slavery to end then. Ending importation and ending slavery within the United States were different questions.
Question: Correct this claim: “The Convention agreed that slavery would end in 1808.”
Open the explanation
The agreement concerned Congress’s power to prohibit importation. It protected that trade from a congressional prohibition before 1808; it did not set a date for abolishing slavery.
Source: Constitution, Article I, Section 9, Clause 1
05 · Assurances about a Bill of RightsA ratification-era accommodation, followed by amendments.
The disagreement: During ratification, Anti-Federalists feared that expanded national power and the absence of a comprehensive declaration of rights would threaten liberty. Federalists defended the proposed framework and its structural safeguards.
The accommodation: Supporters’ assurances that they would pursue amendments protecting individual rights helped build support for ratification. Congress later proposed amendments; the states ratified the first ten in 1791.
Effect on power: The Bill of Rights added explicit limits on federal authority and protections for individuals. It also affirmed retained rights and reserved powers.
AP distinction: This was part of the later ratification settlement. The Philadelphia Convention did not write the first ten amendments into the 1787 Constitution.
Question: How could a promise of later amendments move a skeptical state convention toward approval?
Open the explanation
It offered a way to accept the new governing structure while seeking additional protections against abuses of national power. It addressed a specific objection without requiring the entire Constitution to be redrafted before ratification.

3 · AP essential: language for explaining the system
Use each term in a causal explanation| Term | Meaning | Application to this topic |
|---|
| Bicameral legislature | A legislature with two chambers. | The Great Compromise created a House and a Senate with different rules for representation. |
|---|
| Apportionment | Allocation of representation among states by a specified rule. | Population determined House representation; the original formula counted three-fifths of enslaved people. |
|---|
| Federalism | Constitutional division of authority between national and state governments. | The Constitution strengthened national powers while preserving a continuing role for the states. |
|---|
| Separation of powers | Distribution of governmental functions among legislative, executive, and judicial branches. | Congress legislates; the president executes laws; the judiciary decides cases. |
|---|
| Checks and balances | Powers that let institutions restrain or influence other institutions. | A president can veto legislation; Congress can override with the required supermajorities. |
|---|
| Limited government | Government exercises power within legal and constitutional restraints. | Structural checks, enumerated powers, and rights protections constrain officials. |
|---|
| Popular sovereignty | The people are the ultimate source of governmental authority. | A representative system can rest on popular authority even without direct voting on every policy. |
|---|

|---|
| Federalists / Anti-Federalists | Federalists supported ratifying the proposed Constitution; Anti-Federalists opposed it or sought changes and stronger safeguards. | Their disagreement centered on national power, representation, and protections for liberty. |
|---|
CONNECT TO FEDERALIST NO. 51 · TOPIC 1.6: You have already studied Madison’s argument. Apply it here: stronger government needed internal restraints. A veto illustrates checks and balances; distinct branches illustrate separation of powers; national–state division illustrates federalism. A strong response names the mechanism and explains how it limits concentrated power.
Sources: Constitution, Articles I–III and VII · Federalist No. 51 · CED Topics 1.3, 1.5, and 1.6
4 · AP essential: Article V and constitutional change
The framers provided a demanding process for changing the Constitution. It made revision possible without requiring every state to agree, while preventing a temporary simple majority from rewriting the framework.
Two stages: proposal, then ratification| Stage | Route 1 | Route 2 |
|---|
| 1. Propose an amendment | Two-thirds of both the House and Senate vote to propose it. | Two-thirds of state legislatures apply; Congress calls a convention to propose amendments. |
|---|
| 2. Ratify the proposed amendment | Three-fourths of state legislatures approve. | Conventions in three-fourths of the states approve. Congress determines which ratification route is used. |
|---|
NUMBERS TO KEEP STRAIGHT: Amendments: two-thirds to propose; three-fourths to ratify. Under the state-initiated proposal route, the legislatures request a convention; the convention proposes amendments. Original Constitution: nine state conventions under Article VII. Altering the Articles of Confederation required approval by all thirteen state legislatures, following agreement in Congress.
With fifty states: 34 state legislatures can trigger the proposal-convention route; 38 states must ratify an amendment. A proposal does not become part of the Constitution merely because Congress or a convention approved it. The president does not sign or veto constitutional amendments.
Apply it · Thirty-seven states approve
Both houses of Congress propose an amendment by two-thirds votes. Congress selects ratification by state legislatures. Thirty-seven of fifty state legislatures approve. Has the Constitution changed? Explain.
Open the explanation
No. The proposal stage is complete, but ratification requires three-fourths of the states: 38 of 50. Thirty-seven falls short. This shows how the process requires broad national and state agreement.

5 · Read the sources and explain what they do
These short excerpts and guided readings practice source analysis. Read the linked provision, then answer before opening the explanation. Questions and model responses are original classroom practice.
Source A · Representation and state equality
Read
Article I, Sections 2–3. Section 3 includes the words
“two Senators from each State”.
A. Identify the compromise reflected in the House and Senate arrangements.
B. Explain why the Senate provision protected smaller states.
C. Explain one effect of requiring agreement from both chambers.
Open the explanation
A. The Great / Connecticut Compromise. B. Each state received two senators regardless of population, preserving equal state representation in that chamber. C. A coalition with a House majority still needed Senate support, requiring agreement across institutions with different representational rules.
Source B · Slavery and representation
Read the original apportionment clause in
Article I, Section 2, including
“three fifths of all other Persons”.
A. Identify the population referred to by that phrase.
B. Explain how the clause affected House representation.
C. Explain why it also affected presidential selection.
Open the explanation
A. Enslaved people. B. The formula counted three-fifths of the enslaved population, increasing slaveholding states’ representation compared with excluding that population. C. A state’s electoral allocation depended partly on its House seats, so the representational advantage also affected the Electoral College. The clause conferred no voting rights on enslaved people.
Source C · Power to change the Constitution
Read
Article V, including
“ratified by the Legislatures of three fourths of the several States”.
A. Identify the stage of constitutional change described in this excerpt.
B. Describe one proposal method.
C. Explain how Article V illustrates federalism.
Open the explanation
A. Ratification by state legislatures, one of the two ratification routes. B. Congress may propose an amendment by two-thirds votes in both houses. Alternatively, Congress calls a proposing convention after applications from two-thirds of state legislatures. C. Constitutional change gives state institutions a decisive role alongside national institutions; Congress cannot complete an amendment on its own.
Source D · Return to Federalist No. 51
Madison wrote:
“Ambition must be made to counteract ambition.” Read the surrounding paragraph in
Federalist No. 51.
A. Explain the argument.
B. Use one constitutional mechanism to illustrate it.
C. Explain why a stronger executive made this issue more consequential than it had been under the Articles.
Open the explanation
A. Officials have motives to preserve their institution’s authority; the system can use those motives to resist power grabs. B. A president may veto legislation, and Congress may override a veto with two-thirds votes in both houses. Each institution can resist the other. C. Creating a separate executive strengthened enforcement but introduced an office with substantial independent power, increasing the need for constraints.
6 · Essential questions and AP-style practice
WRITE FIRST: Use complete sentences. Identify names the concept. Describe supplies relevant characteristics. Explain shows how or why the arrangement produces a result. These are practice questions, not official College Board items.
1 · Why replace the Articles?
Identify one weakness of the Articles, describe the Constitution’s response, and explain why the response raised a new concern about power.
Open the explanation
Congress lacked an independent taxing power. Article I gave Congress power to tax, improving its ability to fund national responsibilities. Critics could worry that the stronger national government would weaken state authority or burden individuals, making limits on power more consequential.
2 · What did the Great Compromise settle?
Explain the disagreement between larger and smaller states and how the compromise addressed both positions.
Open the explanation
Population-based House seats reflected the argument for representation tied to population. Equal state representation in the Senate protected smaller states. Requiring both chambers’ agreement made each principle relevant to national lawmaking.
3 · What did the slavery compromises leave unresolved?
Compare the Three-Fifths Compromise with the slave-importation provision. Explain one way both protected slaveholding interests.
Open the explanation
The Three-Fifths Compromise determined population counts for representation and direct taxation; the importation provision restricted congressional action before 1808. One increased political influence compared with excluding enslaved people from the representation count; the other delayed federal prohibition of importation. Neither ended slavery or gave enslaved people political rights.
4 · What is the difference between signing and ratifying?
A student argues that the Constitution became binding on every state as soon as delegates signed it in Philadelphia. Correct the claim using Article VII.
Open the explanation
Signing produced a proposal for consideration. Article VII required ratification by conventions in nine states to establish the Constitution among the ratifying states. The Convention’s signatures did not substitute for state ratification.
5 · Why did the Bill of Rights matter?
Explain why an Anti-Federalist might demand a Bill of Rights and why a Federalist might agree to pursue amendments.
Open the explanation
An Anti-Federalist could fear that structural safeguards and limited grants of power would not adequately protect liberty. A Federalist could support additional explicit protections to address objections and secure ratification of the new governing framework.
6 · Why make amendments difficult?
Explain how Article V balanced the need for constitutional change with the need for stability.
Open the explanation
It made change possible through supermajorities instead of requiring ordinary unanimity. Separate proposal and ratification stages prevented a narrow or temporary majority from acting alone, while preserving a path to revisions with broad support.
7 · Required application: security and liberty
In a hypothetical debate following the 9/11 attacks, officials defend expanded national surveillance as necessary for security. Critics object that it threatens privacy. Explain how the disagreement reflects a founding-era tension.
Open the explanation
Officials emphasize the national government’s capacity to protect the public. Critics emphasize limits on power and individual rights. The disagreement continues the founding-era debate over an effective government that remains constrained. A response should explain the competing principles rather than assume every security measure is either automatically valid or automatically invalid.
8 · Required application: public education
In a hypothetical proposal, the national government seeks a larger role in public-school standards. State officials argue that states should make those decisions. Identify the constitutional principle involved and explain the disagreement.
Open the explanation
Federalism. The dispute concerns how authority should be distributed between national and state governments. Supporters might favor common standards or national priorities; opponents might stress state authority and responsiveness to local communities. The founding settlement preserved both levels of government, leaving recurring arguments about their proper roles.
Multiple-choice check
MC 1 · Representation
State A has a much larger population than State B. Which arrangement best reflects the Great Compromise?
- A. Both states receive the same number of representatives in both chambers.
- B. State A receives more House seats; both states receive two senators.
- C. State A receives more senators; both states receive the same number of House seats.
- D. The president chooses each state’s representation.
Open the explanation
B. The House reflects population; the Senate represents states equally. A erases the House distinction; C reverses it; D gives the president an authority the compromise did not provide.
MC 2 · Presidential selection
Which choice best explains the Convention’s Electoral College arrangement?
- A. It required the national popular-vote winner to become president.
- B. It made Congress the ordinary body for choosing the president.
- C. It assigned every state one electoral vote.
- D. It placed selection with state-appointed electors and linked their number to congressional representation.
Open the explanation
D. The arrangement used electors, with allocations based on House seats plus Senate seats. A describes a national popular vote; B ignores the ordinary electoral mechanism; C misstates the allocation.
MC 3 · Slavery compromise
Which statement accurately distinguishes the two slavery-related settlements in Topic 1.5?
- A. One addressed representation and direct taxation; the other delayed Congress’s power to prohibit importation.
- B. One gave enslaved people voting rights; the other promised emancipation in 1808.
- C. Both immediately ended slavery in states with small enslaved populations.
- D. Both concerned only Senate representation.
Open the explanation
A. The settlements addressed different mechanisms. Neither granted voting rights or emancipated enslaved people; the Senate used equal state representation, not the Three-Fifths formula.
MC 4 · Ratification
Which action most directly addressed Anti-Federalist objections about insufficient explicit protections for liberty?
- A. Giving each state an equal number of House seats.
- B. Requiring thirteen states to approve every act of Congress.
- C. Assuring ratification supporters that rights amendments would be pursued.
- D. Allowing the president to amend the Constitution.
Open the explanation
C. Assurances about a Bill of Rights addressed rights-based objections. The other choices describe arrangements the Constitution did not adopt.
FINAL SELF-CHECK: Can you explain each compromise without confusing representation with voting rights, slave importation with slavery, the Convention with ratification, or Article VII with Article V? Can you connect a specific constitutional mechanism to Federalist No. 51?
7 · Helpful context / optional detail
STUDY PRIORITY: Understand the disputes below because they clarify the required compromises. Topic 1.5 does not separately list these plan names, delegate biographies, or meeting details as required memorization. Your teacher may still assign them as course material.
Virginia Plan and New Jersey PlanBackground for understanding the required Great Compromise.
Virginia Plan: Proposed a stronger national government and a two-chamber legislature, with representation tied to population or financial contribution. It favored the influence of more populous states.
New Jersey Plan: Sought to strengthen the existing confederation while retaining equal state voting in a one-chamber Congress. It protected smaller states’ position.
Use the background: Explain how these competing priorities made the Great Compromise attractive. Memorizing plan names is less useful than explaining the representational conflict.
The meeting and its limitsUseful historical setting and questions for deeper discussion.
Delegates from twelve states participated in Philadelphia; Rhode Island sent none. George Washington presided. The Convention met behind closed doors. Its delegates were men, and the process excluded many people whose lives the new government would shape.
Optional discussion: How might confidentiality encourage negotiation while limiting public scrutiny? Whose interests were represented directly, and whose interests did delegates bargain over without their participation?
Read the National Archives history of the Convention
An additional limit within Article VA useful extension after mastering the basic amendment process.
Article V protects a state from losing equal representation in the Senate without its consent. This gives the state-equality principle additional constitutional protection.
Optional question: What does this protection reveal about how strongly smaller states valued their Senate position?
Open the explanation
It shows that equal Senate representation was a foundational assurance, not merely a temporary legislative arrangement. Smaller states sought protection against later changes that could strip away their equal standing.
