Why did socialist movements become increasingly more radical over the nineteenth century, particularly in Eastern Europe?

Question

What will be an ideal response?

Answer 1

Largely repressed by more conservative governments to the east, the movement of mass politics appealing to the working class was seen as something that could potentially spark, or reignite, revolution, and was to be avoided at all costs. In many countries, such as Austria-Hungary, Russia or Bulgaria, there was a greater history of serfdom and relative lack of industrialization compared to the west as well. While the declaration was made that socialists would adhere to international solidarity and never go to war, in the wake of rising nationalism and mandatory military service in all countries except Britain, this was unlikely. Repression of socialist politics in Germany, Russia and Austria-Hungary as being illegal also made the turn to radicalism necessary, as groups like the Socialist Democrats could not function openly (as they could in Britain or France), and therefore drew a more diverse group with differing political philosophies about the need for violence.
