4 June

Philipp Scheidemann is attacked with prussic acid but by a stroke of luck he escapes with his life. Although Scheidemann has not been at the center of Reich politics for a long while, he is still a hated figure in right-wing circles owing to his proclamation of the republic on 9 November 1918.

24 June

Foreign Minister Walther Rathenau is shot by someone in a car overtaking his car on the way from his villa in Grunewald to the Foreign Office. The perpetrators, former Chief Lieutenant Erwin Kern and Reserve Lieutenant Hermann Fischer, are identified quite quickly and arrested at Saaleck Castle near Bad Kösen. Kern is shot attempting to escape; Fischer then commits suicide. Both were members of the Organization Consul and the nationalist “Schutz- und Trutzbund” (Protection and Defiance Federation). On the very same day, Karl Helfferich, a DNVP politician and opponent of Rathenau, is physically threatened by left-wing members of the Reichstag. One day later, Reichskanzler Josef Wirth makes the speech that is to become famous, saying that: “There stands the enemy, dripping poison into a nation’s wounds. There stands the enemy - and there is no question about it: The enemy stands on the right!”
