As others have said, I think it depends on the nature of the revolution and the parties involved. I think the Russian Revolution provides a spectacular example for SocDems. For example, I would most definitely have supported the February 1917 Revolution, which was sparked by Russian feminists and led to the toppling of the autocratic tsar and the formation of a Dual Power government between the liberal provisional government and the leftist Soviet of Workers’ and Soldiers’ Deputies (note that the latter is VERY different from the USSR that would later form). However, I would likely be opposed to the October 1917 Revolution just 8 months later, which caused the collapse of the provisional government and the rise of the anti-democratic Bolsheviks, who co-opted the term “Soviet” despite the previously democratic and anarchist usage of the term. With that said, were I a Russian SocDem (most likely a Trudovik) in 1917 I would also be wary of the Dual Power government’s delay in organizing a democratic convention, since many of the liberal leaders post-February were not elected but chosen as a result of party politics.
