Poale Zion
In Russia, the Poale Zion Left participated in the Bolshevik Revolution and organized a brigade of Poale Zion activists nicknamed the "Borochov Brigade" to fight in the Red Army. The party remained legal until 1928 when it was liquidated by the NKVD. Most other Zionist organizations had been closed down in 1919, but Poale Zion Left remained untouched because it was recognized as a Communist party. In 1919, the Communists of Poale Zion Left split to form the Jewish Communist Party which ultimately joined the Communist Party of the Soviet Union, leading to a sharp loss of membership in Russia. While the Bund was forcibly disbanded in 1921, Poale Zion and Hechalutz were allowed to operate freely in the Soviet Union until 1928.
