The term was applied to a variety of different groups, from those on the right who had been in favour of the war effort since 1914 and even supported aggressive war aims like territorial expansion, to those on the left who had adhered to the Zimmerwald anti-war movement before 1917 but approved of limited defensive war 'in defence of the revolution'.
