“Soviet” is derived from a Russian word signifying council, assembly, advice, harmony, concord, and all ultimately deriving from the Proto-Slavic verbal stem of *vět-iti "to inform", related to Slavic "věst" ("news"), English "wise", the root in "ad-vis-or" (which came to English through French), or the Dutch "weten" (to know; cf. "wetenschap" = science).
A number of organizations in Russian history were called "council" (Russian: сове́т). For example, in Imperial Russia, the State Council, which functioned from 1810 to 1917, was referred to as a Council of Ministers after the revolt of 1905.
According to the official historiography of the Soviet Union, the first workers' council (soviet) formed in May 1905 in Ivanovo (north-east of Moscow) during the 1905 Russian Revolution (Ivanovsky Soviet). However, in his memoirs, the Russian Anarchist Volin claims that he witnessed the beginnings of the St Petersburg Soviet in January 1905. The Russian workers were largely organized at the turn of the 20th century, leading to a government-sponsored trade-union leadership. In 1905, as the Russo-Japanese War (1904-1905) increased the strain on Russian industrial production, the workers began to strike and rebel. The soviets represented an autonomous workers' movement, one that broke free from the government's oversight of workers' unions. Soviets sprang up throughout the industrial centers of Russia, usually organizing meetings at the factory level. These soviets disappeared after the revolution of 1905, but re-emerged under socialist leadership during the revolutions of 1917.
The popular organizations which came into existence during the Russian Revolution were called “Councils of Workmen's and Soldiers' Deputies.” These bodies were supposed to hold things together under the provisional government until the election of a constituent assembly could take place; in a sense, they were vigilance committees designed to guard against counter-revolution. The Petrograd Soviet of 4,000 members was the most important of these, on account of its position in the capital and its influence over the garrison.
