The Russian avant-garde was a large, influential wave of modern art that flourished in the Russian Empire and Soviet Union, approximately 1890 to 1930—although some have placed its beginning as early as 1850 and its end as late as 1960. The term covers many separate, but inextricably related, art movements that flourished at the time; namely Suprematism, Constructivism, Russian Futurism, Cubo-Futurism, Zaum and Neo-primitivism.
