十月詔書
The October Manifesto (), officially "The Manifesto on the Improvement of the State Order" (Манифест об усовершенствовании государственного порядка), is a document that served as a precursor to the Russian Empire's first Russian Constitution of 1906, which was adopted the following year. The Manifesto was issued by Tsar Nicholas II (1868–1918, ruled 1894–1917), under the influence of Sergei Witte (1849–1915), on as a response to the Russian Revolution of 1905. Nicholas strenuously resisted these ideas, but gave in after his first choice to head a military dictatorship, Grand Duke Nicholas, threatened to shoot himself in the head if the Tsar did not accept Witte's suggestion. Nicholas reluctantly agreed, and issued what became known as the October Manifesto, promising basic civil rights and an elected parliament called the Duma, without whose approval no laws were to be enacted in Russia in the future. According to his memoirs, Witte did not force the Tsar to sign the October Manifesto, which was proclaimed in all the churches.
