What this topic is asking
Topic 3.8 asks you to explain how the Constitution was written and ratified. Two things drive the topic: the compromises that made agreement possible at the 1787 convention, and the fierce Federalist versus Anti-Federalist debate over whether to ratify the result. The promise of a Bill of Rights ultimately secured ratification.
The convention and its compromises
The Philadelphia convention of 1787 quickly decided to replace the Articles entirely. The hardest disputes were settled by famous compromises.
The ratification debate
Once written, the Constitution had to be ratified by state conventions, and the country divided.
How ratification was won
The Anti-Federalists' strongest point, the absence of a bill of rights, became the key to ratification. Federalists promised that the first Congress would add one. That promise reassured enough doubters, and the states ratified the Constitution in 1788 and 1789; the Bill of Rights (the first ten amendments) was duly added in 1791.
Worked example: arguing the role of compromise
Try this
Q1. Name the compromise that created a House based on population and a Senate with equal state representation. [Recall]
- Cue. The Great Compromise (Connecticut Compromise), which produced the bicameral Congress.
Q2. Explain how the promise of a Bill of Rights helped secure ratification. [Short explanation]
- Cue. Anti-Federalists' chief objection was the lack of protection for individual liberties, so the Federalists' promise that the first Congress would add a bill of rights reassured enough doubters to win ratification, and the first ten amendments were added in 1791.
