Matthias Erzberger is murdered whilst taking a walk near Griesbach. The perpetrators, Chief Lieutenant Heinrich Tillessen and Heinrich Schulz, are members of the Organisation “Consul” and the Munich “Germanenorden”. Leader of the “Germanenorden”, Captain Lieutenant Manfred von Killinger, had ordered them to assassinate Erzberger. The assassins manage to escape to Hungary and are not sentenced until 1950, when they receive prison terms of 12 and 15 years, respectively. Yet they are only forced to serve two years of these sentences. Killinger is acquitted of the charge of complicity in murder in 1922.

In reaction to the shocking assassination of Matthias Erzberger and at the Wirth government’s suggestion, the Reichspräsident issues an emergency decree (Law for the Protection of the Republic), which allows the Minister of the Interior to ban anti-Republican organizations, meetings and publications. Yet this law is not consistently implemented due to resistance from the conservative-bourgeois regional government in Bavaria. This power is therefore transferred from the Reich Minister of the Interior to the states.
