The House of Councillors (German: Kammer der Reichsräte) was the upper house of the Landtag of the Kingdom of Bavaria during its existence both as an independent state and as a federal subject of the German Empire.
The House of Councillors was established by the 1818 Constitution of the kingdom, and its composition and powers remained unchanged until its abolition under the 1919 Bamberg Constitution.
[1][2] Its members comprised the aristocracy and noblemen, including the royal princes, holders of the crown offices, archbishops, members of the Mediatized Houses in bavaria and hereditary and lifelong nominees of the crown.
[3] The House of Councillors held its sessions in secret, which is one of the reasons why it received little public attention during the Vormärz in Bavaria.
[4] From 1919 on under the Bamberg Constitution in the Weimar Republic, the upper house of the Landtag was abolished and its lower house became a unicameral democratic elected assembly.
