In 1794 the civil riots were largely quelled, the people had perhaps enjoyed sufficient bloodshed, seen enough royals and royalists guillotined. The terror of the last few years seemed pointless and ruthless Robespierre was not popular, his law making too harsh.
He was executed himself. Within days, that situation had encouraged the few royalists left alive. In the west and in the southeast, a royalist “White Terror” broke out. Royalists tried to seize power in Paris but Napolean's army crushed them and the riot did not last long.
Napolean's strength was too great for everyone for he had led with good example and inspiration. The royalists failed in their bid to return to power.
The white Terror was a period in the French revolution in 1795, it was an attack launched against the terrorists, and all who could be accused of doing well out of the French revolution (people associated with the Reign of Terror).
Some men had taken advantage of the Reign of Terror to acquire lands and property by force and murder. The attack was launched by people whose loved ones had been victims of the Great terror or who livelihood had been affected by the government and its supporters before the Thermidorean reactions.
