The term "Red October"  has also been used to describe the events of the month. This name has in turn been lent to a steel factory made notable by the Battle of Stalingrad, a Moscow sweets factory that is well known in Russia, and a fictional Soviet submarine. Ten Days That Shook the World, a book written by American journalist John Reed and first published in 1919, gives a firsthand exposition of the events. Reed died in 1920, shortly after the book was finished. Dmitri Shostakovich wrote his Symphony No. 2 in B major, Op. 14 and subtitled To October, for the 10th anniversary of the October Revolution. The choral finale of the work, "To October", is set to a text by Alexander Bezymensky, which praises Lenin and the revolution. The Symphony No. 2 was first performed by the Leningrad Philharmonic Orchestra and the Academy Capella Choir under the direction of Nikolai Malko, on 5 November 1927. Sergei Eisenstein and Grigori Aleksandrov's film October: Ten Days That Shook the World, first released on 20 January 1928 in the USSR and on 2 November 1928 in New York City, describes and glorifies the revolution and was commissioned to commemorate the event. 7 November, the anniversary of the October Revolution, was the official national day of the Soviet Union from 1918 onward and still is a public holiday in Belarus and the breakaway territory of Transnistria. The October revolution of 1917 also marks the inception of the first communist government in Russia, and thus the first large-scale socialist state in world history. After this Russia became the Russian SFSR and later part of the USSR, which dissolved in late 1991.
