Bayerische Ständeversammlung 1819 to
King Maximilian I Joseph, on the first anniversary of the
constitution of 1818, obverse The
Landtag of Bavaria was founded in 1818, in the
Kingdom of Bavaria. The first assembly was held on 4 February 1819. Originally it was called the
Ständeversammlung and was divided into an upper house, the
Kammer der Reichsräte (House of Councillors), and a lower house, the ''
(House of Representatives). With the act to reform the election of the representatives in 1848 the Ständeversammlung
was de facto renamed the Landtag'' (state diet). The name Landtag was used occasionally before this act. In the
Weimar Republic, from 1919 on, under the , the upper house of the
Landtag was abolished and its lower house became a unicameral democratic elected assembly. After the
Nazi seizure of power in 1933, the
Landtag underwent
Gleichschaltung like all German state parliaments. It was dissolved on 30 January 1934 as a result of the "
Law on the Reconstruction of the Reich". After the
Second World War, the new
Constitution of Bavaria was enacted and the first new
Landtag elections took place on 1 December 1946. Between 1946 and 1999 there was again an upper house, the
Senate of Bavaria. The CSU has dominated the Bavarian
Landtag for nearly the entire post-war period. The CSU's
2003 election victory was the first time in the history of the
Federal Republic of Germany that any party had won a two-thirds majority of seats in an assembly at any level. Five years later in
2008, the CSU saw a stunning reversal of fortunes, and failed to win a majority of seats in Bavaria for the first time in 46 years. In the aftermath of this result, the SPD floated the idea that the four other parties should all unite to form a government excluding the CSU, as it had "lost its mandate to lead": however, the FDP were not interested, and opted to form a coalition with the CSU. ==Composition==
