Malevich's trajectory in many ways mirrored the tumult of the decades surrounding the October Revolution (O.S.) in 1917. In its immediate aftermath, vanguard movements such as Suprematism and Vladimir Tatlin's Constructivism were encouraged by Trotskyite factions in the government. Malevich held several prominent teaching positions and received a solo show at the Sixteenth State Exhibition in Moscow in 1919. His recognition spread to the West with solo exhibitions in Warsaw and Berlin in 1927. From 1928 to 1930, he taught at the Kyiv Art Institute, with Alexander Bogomazov, Victor Palmov, Vladimir Tatlin and published his articles in a Kharkiv magazine, "Nova Generatsia" ("New Generation"). But the start of repression in Ukraine against the intelligentsia forced Malevich return to modern-day Saint Petersburg. From the beginning of the 1930s, modern art was falling out of favor with the new government of Joseph Stalin. Malevich soon lost his teaching position, artworks and manuscripts were confiscated, and he was banned from making art. In 1930, he was imprisoned for two months due to suspicions raised by his trip to Poland and Germany. Forced to abandon abstraction, he painted in a representational style in the years before his death from cancer in 1935, at the age of 56.
