The Russian Social Democratic Labour Party (of Internationalists) (Russian: Российской социал-демократической рабочей партии (интернационалистов)), initially known as the United Social Democrats-Internationalists, was a political party in Russia.

[1] They were critical of Bolshevik tactics but would remain supportive of the Soviet government.

[1] They were a relatively small organization of leftist intellectuals, largely identified with its newspaper Novaya Zhizn ('New Life').

[2][1] Whilst the group was quite small, Novaya Zhizn had a significant readership.

[3] Soviet historiography labelled the party as "the far left of the petty bourgeoisie", arguing that the party had a contradictory position in calling for a socialist government whilst rejecting the notion of an armed uprising.
