At the same time as temperance was flowering, so were crusades for clean water and sanitation, which saved millions of lives. Alcohol, seen as a major scourge of civil society, looked ripe for a once-and-for-all ban that would put mankind on a new course.

The introduction of the income tax made Prohibition fiscally feasible. Women's suffrage made it politically feasible.
