The book 'Ten Days That Shook the World' is about what historical event?

'Ten Days That Shook the World' (1919) is a book by the American journalist and socialist John Reed about the October Revolution in Russia in 1917, which Reed experienced first hand. Reed followed many of the prominent Bolshevik leaders closely during his time in Russia. John Reed died in 1920, shortly after the book was finished, and he is one of the few Americans buried at the Kremlin Wall Necropolis in Moscow, a site normally reserved only for the most prominent Soviet leaders.

'Ten Days That Shook the World' has received mixed responses since its publication in 1919, resulting in a wide range of critical reviews from negative to positive. However, the book was overall positively received by critics at the time of its first publication, despite some critics’ vocal opposition to Reed’s political beliefs.
