Union of Socialists-Revolutionaries Maximalists () was a political party in the Russian Empire, a radical wing expelled from the Socialist-Revolutionary Party in 1906. The Union united agrarian terrorists, the 'Moscow Opposition' and other radical dissidents from the PSR in an independent party. The Maximalists officially split off from the PSR at its Second Congress in Imatra in 1906. Maximalists played a role in both the Revolution of 1905 and the Revolution of 1917. Many former SR Maximalists eventually joined the Russian Communist Party (Bolshevik). Ideology and history Maximalists were so called because they demanded the full implementation of the 'maximum programme' in the expected revolution: full socialisation of the land, factories and all other means of production. The orthodox Socialist-Revolutionaries wanted to start with land reform but defer socialisation of other means of production. The Maximalists also rejected the PSR's version of a 'two-stage' revolution, a theory associated with V.M. Chernov. According to Chernov, the coming revolution in Russia would not be purely 'bourgeois-democratic' as the Social-Democrats claimed, but would include social and economic as well as political reforms. It would be a 'popular-democratic' revolution, and would transition into a full-blown 'labour-socialist' revolution later on. The Maximalists rejected this as Social-Democratic 'attentism' and argued that the coming Russian revolution would not be able to stop half-way; it was the two-stage theory, not Maximalism, that was unrealistic if it thought the toiling masses, once liberated, would content themselves with a bourgeois republic and gradual reforms. The SR Maximalists also had a much more favourable view of terror and expropriation. Before the Azef scandal of 1908, the PSR had endorsed 'political terror', i.e., attacks on state officials and members of the ruling royal family. Many future Maximalists had been involved in such attacks, as well as in 'expropriations' (bank robberies and the like). Such methods had always been controversial in the PSR and were discontinued after Yevno Azef, head of the PSR's 'Combat Organization', was unmasked as a secret police agent. The Maximalists, however, argued for a continuation of 'political terror' and also endorsed 'economic terror', meaning attacks on factory bosses, industrialists, bankers, landowners, etc., or their property. Such actions against 'private' individuals were unacceptable to the orthodox SRs, who denounced them as 'lynch justice'. Meanwhile, on the right, the Popular Socialists who defected from the PSR at the same time as the Maximalists, rejected any terrorism. The Maximalists were often compared
