The Symphony No. 11 in G minor (Opus 103; subtitled The Year 1905) by Dmitri Shostakovich was written in 1957 and premiered, by the USSR Symphony Orchestra under Natan Rakhlin, on 30 October 1957. The subtitle of the symphony refers to the events of the Russian Revolution of 1905.
The title, The Year 1905, recalls the start of the first Russian Revolution of 1905, which was partially fired by the events on 9 January (9 January by the Julian calendar still in use in Russia at the time, modern date of 22 January 1905) date of that year. Some Western critics characterized the symphony as overblown "film music"—in other words, as an agitprop broadsheet lacking both substance and depth. Many now consider the work to carry a much more reflective attitude, one which looks at Russian history as a whole from the standpoint of 1957, four years after the death of Stalin. Another common interpretation is that the symphony is a response to the crushing of the Hungarian Revolution of 1956; it was composed immediately after the uprising, and his widow Irina has said that he had it "in mind" during composition
