Doctors' plot
There was a slight revival in the Birobidzhan idea after the war as a potential home for Jewish refugees. During that time, the Jewish population of the region peaked at almost one-third of the total. But efforts in this direction ended, with the Doctors' plot, the establishment of Israel as a Jewish state, and Stalin's second wave of purges shortly before his death. Again the Jewish leadership was arrested and efforts were made to stamp out Yiddish culture—even the Judaica collection in the local library was burned. In the ensuing years, the idea of an autonomous Jewish region in the Soviet Union was all but forgotten.
