of the most prominent representatives of the pre-war socialist movement: people like Henry Hyndman, Plekhanov and Guesde. More common was an attitude of conditional support for the war, approving a 'defensive' war but rejecting annexations and indemnities. A special case arose in Russia in 1917: After the February Revolution, several Mensheviks and Socialist-Revolutionaries (SRs) who had previously been Internationalists and Zimmerwaldists now favoured 'revolutionary defencism' – continued war effort in defence of the revolution. This was the case with Mensheviks like Fedor Dan and Irakli Tsereteli, SRs like Avram Gots and Nikolai Avksentiev and Trudoviks like Alexander Kerensky. In 1917 some Bolsheviks took also this position, before Lenin returned to Russia and successfully opposed this view. On the Internationalist side, too, there were divisions. Most Internationalists favoured passive resistance to the war and called for an international peace agreement, 'without annexations or indemnities'. Jaurès, Kautsky, Bernstein, Martov and Chernov belonged to this camp; so, at first, did the Bolshevik Lev Kamenev. A minority led by Lenin advocated 'revolutionary defeatism': instead of seeking a peace agreement that would restore the status quo ante, socialists should seek to convert the 'imperialist war' into a revolutionary 'civil war', with each socialist party working for the defeat of its own country. Effects by country The schism caused splits in many European socialist parties. In France, the split between socialists and communists did not occur until 1920. In Germany, the Independent Social-Democrats (USPD) formally separated from the majority Social Democratic Party of Germany (SPD) in 1917, and the more radical Spartacist League formed the nucleus of the post-war German Communist Party (KPD). Italy was a special case: whereas, in most European socialist parties, Defencists predominated (at least at the beginning of the war), in Italy, the majority of the members and most of the leaders of the Socialist Party, from reformists to radicals, were against Italy's entry into the war, while a minority, led by the former Maximalist and future fascist dictator Benito Mussolini, campaigned for Italian intervention and was expelled from the party for it. Only the Serbian socialists remained fairly uniformly anti-war. Russia Divisions in Russia were especially complicated and affected party alignments during the Russian Revolution. The Mensheviks and Socialist-Revolutionaries were badly divided. A small minority on the right took an out-and-out Social Patriotic stance, even supporting territorial expansion as a war aim. Plekhanov and the 'Grandmother of the Revolution, Breshkovskaia, belonged
