The 1905 Russian Revolution was sparked by several factors, including unrest among peasants and urban workers, a weak economy, Russia's humiliating defeat in the Russo-Japanese War, and extensive foreign investments in Russia. Major events included Bloody Sunday in January 1905, when Cossacks opened fire on peaceful protesters in St. Petersburg, and the mutiny on the battleship Potemkin in June 1905. In response to the unrest, Tsar Nicholas II issued the October Manifesto in 1905, which established basic civil liberties and agreed to the creation of an elected parliament, the Duma. However, the revolution ultimately failed to unseat the Tsar or establish a democratic government in Russia.
