Why did Marc Chagall leave Russia permanently in 1922?

Marc Chagall left Russia permanently in 1922 following a period of intense frustration. Although he was initially enthusiastic about the Russian Revolution of 1917 and served as a commissar for art in the Vitebsk region, his experience eventually soured. After two and a half years of dedicated work on local art projects, he faced increasingly bitter aesthetic and political quarrels with the faculty of the art academy he had helped establish.

Disillusioned by these conflicts, he moved to Moscow to focus on theater design before ultimately deciding to leave the country for good in 1922, eventually settling in Paris.1
