during a strike by oil workers, but was arrested in August. He escaped and reached Moscow on 13 October,. There he was originally one of a triumvirate who led the Moscow Bolsheviks. The other two - V.L.Shanster and M.I.Vasilyev-Yushin - were arrested on 7 December, which meant that Liadov was leading the Moscow Bolsheviks when the workers put up barricades and fought the army for control of the working class districts of Moscow, but, according to the historian J.H.L.Keep, Liadov "spent these two days wandering aimlessly through the streets. He had no headquarters from which to transmit orders to the militia groups." In January 1906, after the Moscow insurrection had been suppressed, Liadov travelled the Urals and Siberia, helping to organise the 4th Congress of the Russian Social Democratic Labour Party in Stockholm, which he attended as a delegate. He was also a delegate to the Fifth Party Congress in London in May 1907. When the Bolsheviks split in June 1909, Liadov backed the Otzovisty faction, led by Alexander Bogdanov, and accused Lenin of being obsessed with "the statutory strengthening of his personal influence", an attitude which, he alleged, meant that the Bolsheviks had lost touch with the workers. In 1911, he moved to Baku and gave up illegal activity, to work in the oil industry, and later as an employee of the Nobel brothers. After the February Revolution, in 1917, Liadov was elected acting Chairman of the Baku Soviet, until the chairman, Stepan Shaumian, returned from exile in Siberia, and was appointed editor of the soviet's newspaper, Izvestya Bakinskogo soveta. At this time, he was aligned with neither faction of the RSDLP, but was ousted when the Bolsheviks seized control in October 1917. He was arrested when the Turkish army occupied Baku, held in prison for two months, then deported to Georgia, where he worked for the Menshevik government for two years. Liadov returned to Moscow in 1920. He was then readmitted into the Bolshevik Party and served on the Supreme Council of the National Economy. From 1923 to 1929, he was rector of the Sverdlov Communist University. Then he headed Glavnauka. His history of the party, first published in 1906–07, was reissued in 1923–26. He was also head of the agitprop department of the Moscow regional party, whose first secretary was Nikolai Uglanov. In 1929, when Stalin began the forced collectivisation of agriculture, Liadov, supported the right wing
