What is the Russian avantegarde movement?

The term avante garde refers generally to art for the sake of social progress. But sometimes, the term is also used to refer to experimental and innovative art without any specific social purpose. The term is used with the former meaning in Russia, which experienced a great art reform in the period 1917-1932 in the wake of the Russian revolution. The Russian avantegarde movement is attributed to a group of about twenty artists, whose works had a great influence on the abstract art of the country.
