Topic 3.9 Notes – The Constitution

What the Constitution Created

The Constitution was written in 1787 and took effect in 1789. It replaced the Articles of Confederation, which had created a weak central government that mostly had to ask states for cooperation.

The new system was a federal republic. That means power was shared between national and state governments, and people ruled through elected representatives.

The core idea was a limited but dynamic central government.

• Limited meant power was divided and restrained.
  • Government had to follow a written Constitution.
  • Power was split across levels and branches.
  • Leaders were checked by other leaders.
• Dynamic meant the national government could actually do things the Articles could not.
  • It could tax, regulate commerce, enforce laws, conduct foreign policy, and maintain armed forces.

The Constitution rested on popular sovereignty and republican government. “We the People” mattered because it claimed authority came from the people, not just from the states.

This still was not a direct democracy.

• Only the House of Representatives was directly elected by voters.
• Senators were originally chosen by state legislatures.
• The president was chosen by the Electoral College.
• Federal judges were appointed.

A lot stayed the same from the Revolution. Americans still believed in republicanism, written constitutions, and distrusted concentrated power. States still mattered a lot. The big change was that the new national government could act directly on individuals, not just make requests to states.

Political participation also stayed narrow. Women, enslaved people, many poor men, and American Indians were still excluded from full political rights.

How Power Was Divided

The Constitution tried to prevent tyranny in two ways at once. It split power between governments and within the national government.

This chart puts those two ideas together by showing federalism across levels of government and the separation of powers within each level.

Federalism and separation of powers

Federalism

Federalism divided power between the national and state governments.

• Enumerated powers of the national government included the power to tax, borrow money, regulate interstate and foreign commerce, coin money, declare war, raise armies, and create lower courts.
• Concurrent powers were shared. Both states and the national government could tax.
• States were denied some powers, including making treaties and coining money.
• The supremacy clause made the Constitution and valid federal laws the highest law in the land.
• The Tenth Amendment later reinforced that powers not given to the national government were reserved to the states or the people.

Separation of powers

National power was also split into legislative, executive, and judicial branches. Each branch had its own job so no single part of government could control everything.

Checks and balances

1. Congress passes a bill in both houses.
2. The president signs it or vetoes it.
3. Congress can override a veto with a two-thirds vote in both houses.
4. The courts can later rule on whether the law is constitutional.

Shared power also showed up in appointments and treaties. The president nominated officials and judges, but the Senate had to approve them.

The Three Branches

Legislative branch

Article I created a bicameral Congress.

Congress had major powers over taxation, commerce, war, and spending. The necessary and proper clause, or elastic clause, gave Congress flexibility to carry out its listed powers.

Congress also checked others through impeachment, veto overrides, and Senate confirmation of appointments and treaties.

Executive branch

Article II created a single president, chosen through the Electoral College.

The president could enforce laws, act as commander in chief, veto bills, negotiate treaties, nominate officials and judges, and grant pardons. This office was much stronger than anything under the Articles, but it was still limited by impeachment, Senate approval, and Congress’s control of funding.

Judicial branch

Article III created the Supreme Court and allowed lower federal courts. Judges served for life during “good behavior,” which helped keep them independent.

Federal courts heard cases involving the Constitution, federal laws, treaties, and disputes between states. Judicial review was not clearly written out in 1787, but it became established in Marbury v. Madison (1803). That date matters because students often mix up what the Constitution created with what later practice confirmed.

Why the New Government Was Both Limited and Flexible

The Constitution limited government by giving it enumerated powers, not unlimited authority. It banned bills of attainder and ex post facto laws, protected habeas corpus except in extreme cases, and banned religious tests for federal office.

The Bill of Rights was added in 1791 and protected speech, religion, press, assembly, due process, jury rights, and protections against unreasonable searches and seizures.

It was also flexible. The necessary and proper clause let Congress adapt. Broad powers over taxation, spending, and commerce could grow in practice. Article V created an amendment process that was hard, but still much easier than the Articles’ rule of unanimity. The Bill of Rights itself proved the system could change without being replaced.

Continuity and Change from the Articles

The Constitution kept some old ideas alive.

• Republican government stayed.
• There was still no king.
• States kept their own governments and major authority.
• The national government still handled diplomacy, war, and western lands.
• Americans still feared tyranny.

The changes were huge.

• Confederation → federal system
• Unicameral Congress → bicameral Congress
• No direct taxing power → direct federal taxation
• Weak commerce power → regulation of interstate and foreign trade
• No executive → president
• No national judiciary → Supreme Court and lower federal courts
• Dependence on state compliance → federal supremacy

The Constitution also built in compromises over slavery.

• The three-fifths clause increased Southern representation.
• The slave trade could not be banned before 1808.
• The fugitive slave clause required the return of escaped enslaved people.

Those clauses are a major APUSH point. The Constitution strengthened the national government, but it also protected slavery and pushed that conflict into the future.
