Historical Context
Revolutions don't emerge from nowhere. They follow measurable preconditions — rising inequality,
collapsing institutional trust, economic stress, and mass mobilization. This page compares current
US indicator levels against the conditions that preceded eight major revolutions spanning 1789 to 2025.
All historical values are scholarly estimates based on academic research, not precise measurements.
They are mapped to the same 0.0-1.0 scale used by the Revolution Index to enable direct comparison.
The French monarchy collapsed under extreme wealth concentration, crushing tax burdens on commoners, and a bankrupt state unable to feed its people. The top 10% held 90% of national wealth while bread consumed 50-80% of a laborer's wages. The storming of the Bastille became the defining symbol of popular revolt against institutional failure.

A Note on Methodology
Historical factor values are approximate estimates derived from academic research, economic history
papers, and scholarly analyses. They are not precise measurements — pre-modern economies lacked the
statistical infrastructure for exact Gini coefficients or unemployment rates. Where multiple scholarly
estimates exist, we use the midpoint of the range. These comparisons are intended to provide context
and perspective, not definitive equivalences.
