Following the Revolution of 1905, the Tsar made last attempts to save his regime, and offered reforms similar to most rulers when pressured by a revolutionary movement. The military remained loyal throughout the Revolution of 1905, as shown by their shooting of revolutionaries when ordered by the Tsar, making overthrow difficult. These reforms were outlined in a precursor to the Constitution of 1906 known as the October Manifesto which created the Imperial Duma. The Russian Constitution of 1906, also known as the Fundamental Laws, set up a multiparty system and a limited constitutional monarchy.
