On 24 June 1922, two months after the signing of the
Treaty of Rapallo, Rathenau was assassinated. He was being chauffeured from his house in
Berlin-Grunewald to the Foreign Office in the
Wilhelmstraße when his car was passed by another with
Ernst Werner Techow behind the wheel and Erwin Kern and
Hermann Fischer in the back seat. Kern opened fire with a submachine gun at close range, killing Rathenau almost instantly, while Fischer threw a hand grenade into the car before Techow quickly drove them away. Also involved in the plot were Techow's younger brother Hans Gerd Techow, future writer
Ernst von Salomon, and Willi Günther (aided and abetted by seven others, some of them schoolboys). All conspirators were members of the ultra-nationalist secret
Organisation Consul. A memorial stone in the Königsallee in Grunewald marks the scene of the crime. Historian Martin Sabrow points to
Hermann Ehrhardt, the leader of the Organisation Consul, as the one who ordered the murders. Ehrhardt and his men believed that Rathenau's death would bring down the government and prompt the Left to act against the Weimar Republic, thereby provoking civil war in which the Organisation Consul would be called on for help by the
Reichswehr. After an anticipated victory Ehrhardt hoped to establish an authoritarian regime or a military dictatorship. He carefully saw to it that no connections between him and the assassins could be detected. Although Fischer and Kern contacted the Berlin chapter of the Organisation Consul to use its resources, they mainly acted on their own in planning and carrying out the assassination. The historian Michael Kellogg argued that
Vasily Biskupsky,
Erich Ludendorff and his advisor
Max Bauer, all members of the
Aufbau Vereinigung, a group of tsarist exiles and early Nazis, colluded in the assassination of Rathenau, although the degree of their participation was not entirely clear. Millions of Germans gathered in the streets to express their grief and demonstrate against counter-revolutionary terrorism. When the news of Rathenau's death became known in the
Reichstag, the session turned into turmoil.
DNVP politician
Karl Helfferich in particular became the target of scorn because he had recently made a vitriolic attack upon Rathenau. During the official memorial ceremony the next day, Chancellor
Joseph Wirth from the
Centre Party made a speech which soon became famous. While pointing to the right side of the parliamentary floor, he said, "There is the enemy – and there is no doubt about it: The enemy is on the right!" The crime itself was soon solved. Willi Günther had bragged about his participation in public. After his arrest on 26 June, he confessed to the crime without holding anything back. Hans Gerd Techow was arrested the following day, and Ernst Werner Techow, who was visiting his uncle, was taken into custody three days later. Fischer and Kern, however, remained on the loose. After a daring flight, which kept Germany in suspense for more than two weeks, they were finally spotted at
Saaleck Castle in
Thuringia, whose owner was a secret member of the Organisation Consul. On 17 July, they were confronted by two police detectives. While waiting for reinforcements during the standoff, one of the detectives fired at a window, unknowingly killing Kern by a bullet in the head. Fischer then took his own life. When the case was brought to court in October 1922, Ernst Werner Techow was the only defendant charged with murder. Twelve more defendants were arraigned on various charges, among them Hans Gerd Techow and Ernst von Salomon, who had spied out Rathenau's habits and kept in contact with the Organisation Consul, as well as the commander of the Organisation Consul in Western Germany, Karl Tillessen, a brother of
Matthias Erzberger's assassin
Heinrich Tillessen, and his adjutant Hartmut Plaas. The prosecution left aside the political implications of the plot and focused upon the issue of antisemitism. Before his assassination, Rathenau had been the frequent target of vicious antisemitic attacks, and the assassins had also been members of the violently antisemitic
Deutschvölkischer Schutz- und Trutzbund. According to Ernst Werner Techow, Kern had argued that Rathenau had to be murdered because he had intimate relations with
Bolshevik Russia and had even married his sister to the communist
Karl Radek – a complete fabrication – and that Rathenau himself had confessed to being one of the three hundred "Elders of Zion" as described in the notorious antisemitic forgery
The Protocols of the Elders of Zion. (Ernst von Salomon later claimed that Kern's argument was merely a pretext. Historian
Norman Cohn believes that Techow's evidence stands.) and Defence Minister

The prosecution was unable to fully uncover the involvement of the Organisation Consul in the plot. Tillessen and Plaas were convicted of non-notification of a crime and sentenced to three and two years in prison, respectively. Salomon received five years imprisonment for accessory to murder. Ernst Werner Techow narrowly escaped a death sentence when, in a last-minute confession, he managed to convince the court that he had acted only under the threat of death by Kern. Instead he was sentenced to fifteen years in prison for being an accessory to murder. Initially, the reactions to Rathenau's assassination strengthened the Weimar Republic. The most notable response was the enactment of the
Law for the Protection of the Republic, which took effect on 22 July 1922. It set up special courts to address politically motivated violence, established severe penalties for political murders and gave government the authority to ban extremist groups. As long as the Weimar Republic existed, the date 24 June remained a day of public commemorations. In public memory, Rathenau's death increasingly appeared to be a martyr-like sacrifice for democracy. The situation changed with the
Nazi seizure of power in 1933. The Nazis systematically wiped out public commemoration of Rathenau by destroying monuments to him, closing the Walther-Rathenau-Museum in his former mansion and renaming streets and schools dedicated to him. Instead, a memorial plate to Kern and Fischer was solemnly unveiled at
Saaleck Castle in July 1933, and in October 1933, a monument was erected on the assassins' grave. The
Nuremberg U-Bahn station
Rathenauplatz is not only named after him but also bears his face in portrait along the walls. ==Fictional portrayals==
