The Girondins, or Girondists, were members of a loosely knit political faction during the French Revolution. From 1791 to 1793, the Girondins were active in the Legislative Assembly and the National Convention. Together with the Montagnards, they initially were part of the Jacobin movement. They campaigned for the end of the monarchy, but then resisted the spiraling momentum of the Revolution, which caused a conflict with the more radical Montagnards. 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 eventual mass execution of the Girondins. This event is considered to mark the beginning of the Reign of Terror.
