Could the Tsarist system in Russia have plausibly fallen before a revolution at any point between the end of the Napoleonic Wars and the beginning of the First World War?
What could make revolutionaries succeed not only in initial overthrow, but also in defeating any reactionary attempts to restore the monarchy?
In parallel with OTL, the "obvious" first places to look are any of the wars of the intervening period, for instance defeat in the Crimean War, Ottoman Wars, or Japanese War, or another alternative war or version of these war, possibly against more enemies, leading to discrediting of the regime.
But are there non-war related causes potentially being overlooked?
