On the following day, similar councils were established in Mannheim and Karlsruhe and the entire Badische state ministry stepped down.

[3] Kurt Eisner, Independent Social Democratic (USPD) Minister-President of the People's State of Bavaria, was assassinated on 21 February 1919.

The Baden USPD and Communist Party of Germany (KPD) held a demonstration mourning Eisner in Mannheim on 22 February, which was attended by 10,000-40,000 people.

The government of Baden declared a state of emergency and banned all gatherings, demonstrations, distributions of pamphlets, and public carrying of weapons.

[7] On 5 March, the government announced that the 110th Infantry Regiment would be withdrawn from Mannheim and replaced by a different battalion to support the police.

The 2nd Volunteer Battalion was moved from Bruchsal to Mannheim on 7 March, and aided the police in arresting leaders of the uprising and prisoners freed from the castle.

[8] After the Nazi seizure of power, Baden, like all other German states, was subjected to the process of Gleichschaltung (coordination).

Between August 1940 and May 1945, Gau Baden was renamed "Baden-Elsass" and extended westwards to include the occupied French district of Alsace.

The division was made so that the Autobahn connecting Karlsruhe and Munich (today the A8) was completely contained within the American zone.

Baden was subdivided into four administrative districts (Landeskommissärbezirke, similar to the modern Regierungsbezirke) based in Karlsruhe, Mannheim, Freiburg and Konstanz.
