So I've been working on something for a mod for Victoria 2 by getting it so that political ideologies won't grow much until that political idea is translated into the language like the Communist Manifesto. And in doing research on this it seems that it wasn't until after the Paris Commune as well as the international that the socialist party movement grew. I also looked at the Reichstag composition over time and it seems to support this but I was wondering what askhistorians thought. I was also thinking it could be a part of growing industrialization and higher literacy but I'm no historian
The Paris Commune was hugely important to Marx and Engel, the latter of whom looked on the commune as a model for his 'dictatorship of the proletariat': A directly democratic system, in which public servants were elected for short terms, paid like other workers, and based on universal suffrage.
Marx vision of a democratic, constitutional system developed into the Erfurt Programme of 1891, drawn up by Karl Kautsky, the leader of the German Social Democratic Party. The SDP subsequently became the model for socialist parties across Europe, including the Russian Social Democratic Labour Party, which split over issues of party membership to form the Bolsheviks and the Mensheviks.
