White Terror followed. Kun managed to escape to the Soviet Union, where he co-led murder of tens of thousands of White Russians. He was killed in the 1930 Soviet purges. In Italy, the events known as the Biennio Rosso were characterised by mass strikes, worker demonstrations and self-management experiments through land and factory occupations. In Turin and Milan, workers' councils were formed and many factory occupations took place led by anarcho-syndicalists organised around the Unione Sindacale Italiana. There was a short-lived Persian Socialist Soviet Republic in 1920–21. Patagonia Rebelde was a syndicalist-led revolution in Argentina lasting for a year and a half from in 1920–21. The anarchist-led Guangzhou City Commune in China lasted six years from 1921. In 1924, the Mongolian People's Republic was established and was ruled by the Mongolian People's Party. The Shinmin Prefecture in Manchuria lasted two years from 1929. Many of these revolutions initiated societies and economic models that have been described as socialist. 4th World Congress of the Communist International In 1922, the fourth congress of the Communist International took up the policy of the united front. It urged communists to work with rank and file social democrats while remaining critical of their leaders. They criticised those leaders for betraying the working class by supporting the capitalists' war efforts. The social democrats pointed to the dislocation caused by revolution and later the growing authoritarianism of the communist parties. The Labour Party rejected the Communist Party of Great Britain's application to affiliate to them in 1920. On seeing the Soviet State's growing coercive power in 1923, a dying Lenin said Russia had reverted to "a bourgeois tsarist machine ... barely varnished with socialism". After Lenin's death in January 1924, the Communist Party of the Soviet Union—then increasingly under the control of Joseph Stalin—rejected the theory that socialism could not be built solely in the Soviet Union in favour of the concept of socialism in one country. Despite the marginalised Left Opposition's demand for the restoration of Soviet democracy, Stalin developed a bureaucratic, authoritarian government that was condemned by democratic socialists and anarchists for undermining the Revolution's ideals. The Russian Revolution and its aftermath motivated national Communist parties elsewhere that gained political and social influence, in France, the United States, Italy, China, Mexico, the Brazil, Chile and Indonesia. Left-wing groups which did not agree to the centralisation and abandonment of the soviets by the Bolshevik Party (see
