Jews were overrepresented among revolutionary socialist movements. [fact]
Just as Jews, because they were barred from so many other industries, were overrepresented in finance, Jews were also overrepresented among revolutionary socialists and communists. Like, really overrepresented. Their ranks included, but were by no means restricted to, Leon Trotsky and much of the Menshevik and Bolshevik leadership at the heart of the Russian Revolution; Rosa Luxemburg and many of her comrades in the Spartacus League who hoped to bring a more democratic version of the revolution to Germany; Vladimir Medem and the entire leadership of the Bund; Emma Goldman and the New York anarchist left; and Walter Benjamin, Theodor Adorno, and others in the Frankfurt School.
XREF: Connects to the parallel overrepresentation of Jews in finance mentioned in the same passage, both stemming from exclusion from other industries.
