The Russian Revolution of 1905, also known as the First Russian Revolution, was a wave of mass political and social unrest that spread through vast areas of the Russian Empire, some of which was directed at the government. It included worker strikes, peasant unrest, and military mutinies. It led to constitutional reform (namely the "October Manifesto"), including the establishment of the State Duma, the multi-party system, and the Russian Constitution of 1906.
