Claim: The Girondins were a part of the Reign of Terror movement, and never caused conflict with Montagnards.
Evidence: They dominated the movement until their fall in the insurrection of 31 May – 2 June 1793, which resulted in the domination of the Montagnards and the purge and mass execution of the Girondins. This event is considered to mark the beginning of the Reign of Terror.
