1918–1933
United States
Explains why dissatisfaction with Prohibition did not automatically produce Repeal: organizations, political opportunity, congressional procedure, and state convention campaigns converted opposition into constitutional change.
Research hold closed 2026-09-01. Seven new dated events and the existing December 5 Repeal event now anchor the period with five complete independent sources plus the original scholarly synthesis. Causal weights remain qualified; no public-opinion percentages or organization membership totals are implied.
Organized Repeal developed through national opposition groups, women-led mobilization and party realignment, Depression-era economic arguments, a successful presidential campaign, a deliberately chosen state-convention mechanism, and the decisive ratification of the Twenty-first Amendment.
Verified period model
Repeal required more than public frustration. National organizations created durable opposition; Pauline Morton Sabin and WONPR supplied a women-led, cross-party mobilization example; Depression-era tax arguments and Roosevelt’s 1932 campaign created a favorable federal opening; Congress selected a state-convention route; and campaigns in the states supplied the necessary ratifications.

Publication guardrails
- Do not treat dissatisfaction or the Depression as self-executing causes.
- Do not claim all women, Republicans, Democrats, or repeal advocates shared the same motives.
- Do not quantify organizational strength or public opinion without separate evidence.
- Keep congressional submission, state ratification, legal Repeal, and post-Repeal industrial recovery distinct.
