On the French Revolutionary calendar, that date was 9 Thermidor: For historians of revolutionary movements, the term Thermidor has come to mean the phase in some revolutions when power slips from the hands of the original revolutionary leadership and a radical regime is replaced by a more conservative regime, sometimes to the point where the political pendulum may swing back towards something resembling a pre-revolutionary state. Edit to add: Leon Trotsky, in his book The Revolution Betrayed, alleges the rise of Joseph Stalin to power was a Soviet Thermidor.
