few days after it had broken out. Meanwhile, Socialist Revolutionary leaders in exile, many of them living in Switzerland, had been the glum spectators of the collapse of international socialist solidarity. French and German Social Democrats had voted in favour of their respective governments' war efforts. Georgi Plekhanov in Paris had adopted a violently anti-German stand, while Alexander Parvus supported the German war effort as the best means of ensuring a revolution in Russia. The Mensheviks largely maintained that Russia had the right to defend herself against Germany, although Julius Martov (a prominent Menshevik), now on the left of his group, demanded an end to the war and a settlement on the basis of national self-determination, with no annexations or indemnities. It was these views of Martov that predominated in a manifesto drawn up by Leon Trotsky (at the time a Menshevik) at a conference in Zimmerwald, attended by 35 Socialist leaders in September 1915. Inevitably Vladimir Lenin, supported by Zinoviev and Radek, strongly contested them. Their attitudes became known as the Zimmerwald Left. Lenin rejected both the defence of Russia and the cry for peace. Since the autumn of 1914, he had insisted that "from the standpoint of the working class and of the labouring masses the lesser evil would be the defeat of the Tsarist Monarchy"; the war must be turned into a civil war of the proletarian soldiers against their own governments, and if a proletarian victory should emerge from this in Russia, then their duty would be to wage a revolutionary war for the liberation of the masses throughout Europe. Economic and social changes An elementary theory of property, believed by many peasants, was that land should belong to those who work on it. At the same time, peasant life and culture was changing constantly. Change was facilitated by the physical movement of growing numbers of peasant villagers who migrated to and from industrial and urban environments, but also by the introduction of city culture into the village through material goods, the press, and word of mouth. Workers also had good reasons for discontent: overcrowded housing with often deplorable sanitary conditions, long hours at work (on the eve of the war, a 10-hour workday six days a week was the average and many were working 11–12 hours a day by 1916), constant risk of injury and death from poor safety and sanitary conditions, harsh discipline (not
