What caused the rise of many revolutionary parties?

Russia was defeated by Japan, a tiny Asiatic country, in the Russo-Japanese war that took place in 1904 . Discontentment rose to a new height. The Czarist government stood exposed for its inadequacy at the war. The Russians suffered a humiliating defeat and signed a number of secret treaties with Japan. As a result of this a large number of secret revolutionary parties sprang up. The Social Democratic Party was most radical in its character. The Social Democrats turned to catch the attention of industrial workers in the Russian cities and their moral mentor was Karl Marx.
