The US Constitution

US Politics Fundamentals

Chapter 1 · The US Constitution: A Real, Codified Document

UK Politics Fundamentals opened with a real, load-bearing distinction: the UK's constitution is "uncodified" — real, but scattered across statutes, court cases, and unwritten conventions rather than collected in a single document. This course opens on the exact opposite structural fact: the United States has a single, physical, written constitution — and, per Wikipedia's own precise wording, it is "the oldest and longest-standing written and codified national constitution in force in the world." That single sentence is this chapter's own real starting point.

From the Articles of Confederation to Philadelphia

The Constitution wasn't the country's first governing document. The Articles of Confederation, in force from 1781, created a deliberately weak national government — Congress could not levy taxes, regulate interstate commerce, or enforce its own laws on individual citizens. By the mid-1780s that weakness was widely seen as a genuine crisis, and delegates from twelve of the thirteen states (Rhode Island abstained) convened in Philadelphia to fix it.

The Constitutional Convention ran from May 25 to September 17, 1787, meeting at Independence Hall. What the delegates produced went well beyond a patch — a wholly new framework of government — and the finished document was signed on September 17, 1787.

The Great Compromise Two competing plans deadlocked the Convention for weeks. The Virginia Plan (proposed 29 May 1787 by Edmund Randolph) wanted a bicameral Congress with both chambers apportioned by population — favoring large states. The New Jersey Plan (proposed 15 June 1787 by William Paterson) wanted a single chamber with equal votes per state, preserving the Articles' own structure — favoring small states. Roger Sherman's real compromise, adopted 16 July 1787, split the difference: a House of Representatives apportioned by population, and a Senate with two seats per state regardless of size. That single structural fix is the reason the US Congress has two chambers elected on two entirely different logics — a fact Chapter 3 builds on directly.

Ratification: Nine of Thirteen

Signing the document in Philadelphia didn't make it law. Article VII set the bar for ratification deliberately high but not unanimous: nine of the thirteen states had to ratify it in state conventions before it would take effect among those states. New Hampshire became the ninth state to ratify on 21 June 1788, clearing that threshold. The new government took effect on 4 March 1789, the date the first Congress convened; George Washington was inaugurated as the first President on 30 April 1789.

A written document is not the same as a static one "Codified" describes where the rules live — collected in one physical document — not how easily they change. As this chapter's own Article V section shows, the US Constitution is in practice one of the hardest constitutions in the world to formally amend. Written-down and easy-to-change are two separate properties, and the US Constitution is a real example of a document that is emphatically the first without being the second.

The Seven Original Articles

The Constitution's own text is organized into seven Articles, each covering a distinct structural question. Later chapters return to most of these in real depth — this table is the map for the rest of the course.

Article I — Legislative

Establishes Congress: the House of Representatives and the Senate. The longest Article in the document. Covered in depth in Chapter 3.

Article II — Executive

Creates the presidency, the Electoral College, and the President's real powers. Covered in Chapters 2 and 6.

Article III — Judiciary

Establishes "one supreme Court" and authorizes Congress to create lower federal courts. Covered in Chapter 4.

Article IV — States

Defines state-to-state and state-to-federal relationships (full faith and credit, extradition, new-state admission). Covered in Chapter 5.

Article V — Amendment

The formal process for changing the Constitution itself. Covered in full below.

Article VI — Federal Supremacy

The Supremacy Clause: the Constitution, federal laws, and treaties are "the supreme Law of the Land," binding on every state.

Article VII — Ratification

Sets the nine-of-thirteen-states threshold described above. Its own job was finished the moment the Constitution took effect.

Article V: How the Document Itself Changes

Article V is worth its own section because it is the mechanism every other structural fact in this course ultimately answers to — and because, deliberately, it makes formal change hard. There are two ways to propose an amendment, and two ways to ratify one, and in over two centuries only one combination of the four has ever actually been used.

StageMethod A (the one always used)Method B (never yet used)
ProposeTwo-thirds of both the House and the Senate vote to propose itTwo-thirds of state legislatures call a national convention to propose it
RatifyThree-fourths of state legislatures approve itThree-fourths of states approve it via specially called state ratifying conventions

Every one of the 27 amendments in force today — including all ten of the Bill of Rights, ratified in 1791 — was proposed by Congress and ratified by state legislatures. The convention-based route in the right-hand column has never once been successfully completed. That's a real, verifiable outcome of the threshold itself: two-thirds of Congress and three-fourths of the states is a genuinely high bar, deliberately designed to require broad, cross-partisan and cross-regional consensus rather than a narrow majority.

Finding: hard-to-amend is a design choice, not an accident Compare this directly against UK Politics Fundamentals Chapter 2's own real finding — that under Parliamentary sovereignty, an ordinary Act of Parliament, passed by a simple majority in a single session, can in principle change any part of the UK's constitutional arrangement, including how Parliament itself is elected. The US Constitution was built to do the structural opposite: making fundamental change require supermajorities specifically so that no single election result, however decisive, can rewrite the rules of the game on its own. This is the single sharpest real difference between the two systems this course will keep returning to.

Codified vs. Uncodified, Side by Side

UK Politics Fundamentals Chapter 1 established that the UK constitution rests on four real sources — Acts of Parliament, court cases, constitutional conventions, and works of authority — with no single document holding them all. The table below puts that finding directly next to what this chapter has just covered.

United StatesUnited Kingdom
Where the rules liveOne physical, written document (plus 27 ratified amendments)Spread across statutes, case law, and unwritten convention — no single document
How ordinary law relates to itAn ordinary federal law that conflicts with the Constitution can be struck down (Chapter 4)Parliament is sovereign; an ordinary Act of Parliament can in principle override anything, including constitutional practice
How it's formally changedArticle V: a deliberately high supermajority threshold (2/3 Congress, 3/4 states)An ordinary Act of Parliament, passed by a simple majority, in a single session
Practical effectFormal change is genuinely rare and slow (27 amendments in 237+ years)Formal change can be fast; real restraint comes mostly from convention, not legal barrier

Notice what this table does not say: it doesn't say one system is more stable or more democratic than the other — only that they solve the same underlying problem (how does a country change its own rulebook?) in genuinely different, verifiable ways. The rest of this course keeps drawing this same UK-vs-US contrast at exactly the points where the two systems structurally diverge, rather than repeating Political Theory Fundamentals' own general comparative-government material from scratch.

Hands-On Exercises

Exercise 1

Walk through what it would actually take, procedurally, for a real amendment to reach the Constitution today — using the two-stage Article V process (propose, then ratify) and naming a specific realistic number of votes/states needed at each stage.

Exercise 2

Explain, in your own words, why the Great Compromise gave the House of Representatives and the Senate two genuinely different logics of representation — and what problem that was actually trying to solve.

Exercise 3

Using this chapter's own codified-vs-uncodified table, explain why "written down" and "easy to change" are two separate properties of a constitution — and give the real US and UK figures that prove they don't have to move together.
