Once Stalin, who was deeply anti-Semitic, took power, the pressure on the Jews increased, and by the end of the 1920s all forms of specifically Jewish activity had been destroyed or emasculated. He then dissolved the Yevsektsiya, leaving supervision of the Jews to the secret police. By this time, Jews had been eliminated from nearly all senior posts in the regime, and anti-Semitism was once more a powerful force within the party.
