<P> Late 1791, a group of Jacobins in the Legislative Assembly propagated war with Prussia and Austria . Most prominent among them was Brissot, other members were Pierre Vergniaud, Fauchet, Maximin Isnard, Jean - Marie Roland . </P> <P> Maximilien Robespierre, also a Jacobin, strongly pleaded against war with Prussia and Austria--but in the Jacobin Club, not in the Assembly where he was not seated . Disdainfully, Robespierre addressed those Jacobin war promotors as' the faction from the Gironde'; some, not all of them, were indeed from department Gironde . The Assembly in April 1792 finally decided for war, thus following the' Girondin' line on it, but Robespierre's place among the Jacobins had now become much more prominent . </P> <P> From then on, a polarization process started among the members of the Jacobin Club, between a group around Robespierre--after September 1792 called' Montagnards' or' Montagne', in English' the Mountain'--and the Girondins . These groups never had any official status, nor official memberships . The Mountain was not even very homogenous in their political views: what united them was their aversion from the Girondins . </P> <P> The Legislative Assembly, governing France from October 1791 until September 1792, was dominated by men like Brissot, Isnard and Roland: Girondins . But after June 1792, Girondins visited less and less the Jacobin Club, where Robespierre, their fierce opponent, grew more and more dominant . </P>
