Mensheviks and SRs

[StoneFrog]

So what was the main differences between these groups and their relations to the Bolsheviks?

I know the Bolsheviks and Bolsheviks split on an issue on what a member of the party is, or something like that.

[GallowsBird]

In a nutshell:

The Mensheviks ("minority") and the Bolsheviks ("majority") were two wings of the Russian Social Democratic Labour Party, the first supporting Martov and the other Lenin. The origin of the split were the oppsing views of the two "factions" in regards to the organisation of the party however as time went on various other differences in ideology formed within the groups.
The Socialist-Revolutionary Party was a different party and followed a more popularist line and were not a marxist party (though some of its members had some Marxist ideas).

Also the (original) main "bone of contention" between the Mensheviks and Bolsheviks was the slightly different ideas of what a "party member" should be, with Lenin's belief being that a party member should work for the party rather than work under the party, that is work for an organisation rather than just under the guidence of the party, and Martov's view vice versa.

Another issue was who were to be on the editorial team of the party newspaper Iskra (Искра).

GallowsBird is correct. I might add that the SRs were tolerated by the Bolsheviks longer than the Mensheviks were. At first they were sort of allied, and helped the Bolshevik government by demonstrating their willingness to allow some choice in elections. Up until the Bolsheviks scrapped democracy, the SRs were the most popular party. The coalition didn't last too long, and some of the SRs ended up trying to assassinate Lenin, and many others joined the Greens or Whites in the civil war.

What were the political differences between Bolsheviks, Mensheviks and Socialist-Revolutionaries?

[StoneFrog]

i kinda got the impression that the SRs had more support from the peasants, where most of there support base was. Were the brosheviks using the SRs to get the peasants to work with the proletariat?

[Arilou Lalee'lay]

The SRs came from the narodnik (populist) movement, which had always focused almost entirely on the peasantry. They viewed the mir, the village council, as a proto-socialist structure that should be expanded upon, not abolished. They paid little attention to the traditional proletariat because it was so small, Russia was just beginning to industrialize. The peasantry, on the other hand, made up the vast majority of the population.

I wouldn't go so far as to say the Bolsheviks were trying to get the peasants to work with the proletariat. They just needed their cooperation until such a time as the petite bourgeois bastards could be eliminated ;)
