Walther Rathenau was a German statesman who served as Foreign Minister during the Weimar Republic. Rathenau initiated the Treaty of Rapallo, which removed major obstacles to trading with Soviet Russia. Although Russia was already aiding Germany’s secret rearmament programme, right-wing nationalist groups branded Rathenau a revolutionary, when he was in fact a moderate liberal who openly condemned Soviet methods. They also resented his background as a successful Jewish businessman. Two months after signing the treaty, he was assassinated in Berlin by the right-wing terrorist group Organization Consul. The public viewed Rathenau as a democratic martyr until the Nazis banned all commemorations of him.
