The trial of 11 U.S. Communist Party leaders begins in New York City on November 1, 1948 for initial appearances, with the substantive proceedings beginning in 1949. It was a highly publicized event during the anti-communist fervor.
They were charged under the Smith Act for conspiring to advocate the overthrow of the U.S. government, leading to their convictions in October 1949 and marking a significant moment in American anti-communist prosecutions.
