How did the russo Japanese war cause the Russian revolution?

Answer 1

The war didn't cause the Russian Revolutions; there were two Russian Revolutions in the early 20th century: the 1905 Revolution which was not successful & the 1917 Bolshevik Revolution (Red Army vs White Army) which succeeded. The Russo-Japanese War of 1904-1905 simply fuelled the 1905 Revolution. Example: It costs much more money for a nation to build Navy battleships than it does to build an Army. The Russians lost nearly a dozen battleships during the war, plus thousands of men; this fuelled the fire of revolution.
Deep enough that the Japanese covert operations most likely began prior to 1902 when the British alliance was signed. Japan would NOT have gone to war without that British agreement. With Japan operating in Britain, they also operated in Russia, financially; supporting any faction that was against the Czarist government...since Japan was to be at war with that government.

Answer 2

Russia's government was shaken by the 1905 Revolutions and Bloody Sunday which were partly caused by the Russo-Jap war. The citizens of Russia were unhappy with their country and wanted them to stop fuelling the Russo-Jap war, decrease work day to 8 hours, clean up the corrupt government and demobilized soldiers of the Russo-Jap war were vandalizing railways in anger. These events lead to more political terrorism in Russia, along with the killing of unarmed, peaceful protestors by the Russian Imperial guard on Bloody Sunday. Russia's foundation of absolute monarchy is challenged as new opposition parties rose.
