The Coup of June 1907, sometimes known as Stolypin's Coup (Russian: Третьеиюньский переворот, romanized: Tretyeiyunskiy perevorot "Coup of June 3rd"), is the name commonly given to the dissolution of the Second State Duma of the Russian Empire, the arrest of some its members and a fundamental change in the Russian electoral law by Tsar Nicholas II on 16 June [O.S. 3 June] 1907. This act is considered by many historians to mark the end of the Russian Revolution of 1905, and was the subject of intense subsequent debate as to its legality. It also created a fundamental shift in the makeup of future Dumas in the Russian Empire: whereas previous laws had given peasants and other lower-class people a larger proportion of electors to the Duma, the new law transferred this to the propertied classes, in an effort to avoid election of the large number of liberal and revolutionary deputies who had dominated the First and Second Dumas. Although it largely succeeded in this objective, it ultimately failed to preserve the Imperial system, which ceased to exist during the Russian Revolution of 1917.
