What Makes a Revolution Succeed? A Synthesis

After comparing six revolutions, students can build their own synthesis. Revolutions tended to begin when states were weakened by war and fiscal crisis, elites were divided, and ordinary people mobilized.

Outcomes depended on several factors: existing institutions, which helped America and hurt Spanish America; the presence of foreign invasion and civil war, which radicalized France and Russia; who led and who participated, which made Haiti an antislavery revolution; and the ideologies guiding leaders, which separated constitutional settlements from a one-party state. Success also depends on the measure chosen: durability, achievement of stated goals, expansion of rights or long-term influence.

No single model fully explains every case, but comparison sharpens judgment. The most useful conclusion is that revolutions are shaped by both structures and choices, and that their meaning keeps changing as later generations ask new questions about who they included and excluded.
