Malevich's assumption that a shifting in the attitudes of the Soviet authorities toward the modernist art movement would take place after the death of Vladimir Lenin in 1924 and Leon Trotsky's fall from power was proven correct in a couple of years, when the government of Joseph Stalin turned against forms of abstraction, considering them a type of "bourgeois" art, that could not express social realities. As a consequence, many of his works were confiscated and he was removed from his teaching position.[citation needed]
