His formulated ideology became known as Jewish Autonomism, once widely popular in eastern Europe, being adopted in its various derivations by Jewish political parties such as the Bund and his Folkspartei. "Autonomism" involved a form of self-rule in the Jewish diaspora, which Dubnow called "the Jewish world-nation". The Treaty of Versailles (1919) adopted a version of it in the minority provisions of treaties signed with new east European states. Yet in early 20th-century Europe, many political currents began to trend against polities that accommodated a multiethnic pluralism, as grim monolithic nationalism or ideology emerged as centralizing principles. After the Holocaust, and the founding of Israel, for a while discussion of Autonomism seemed absent from Jewish politics.
