The ('''CSU''' – ''Christlich-Soziale Union in Bayern e.V.'') is a
Christian Democratic Political Party in
Germany . It operates exclusively in the state of
Bavaria , while its sister party
CDU operates in the rest of the country. Only in
1957 in the state of
Saarland (in the first election after it had rejoined Germany) did the CSU run against CDU candidates, but this section of the CSU later merged with the CDU. On the federal level, the CSU is often perceived as the more socially conservative of the two parties, although recently it has also been seen as more leftist on economic issues than the CDU. At times, especially when the CDU showed weaknesses, there has been considerable tension up to threats to break up the cooperation. Most of the time, however, they work together very closely.
The CSU has led the Bavarian state government practically since it came into existence, and without the need for a coalition government for most of the time. This level of dominance is unique in post-war Germany. On the federal level, it forms a common faction in the ''
Bundestag '' (Federal Parliament) with the CDU.
Edmund Stoiber took over the CSU chairmanship early in 1999. He ran for
Chancellor in
2002 , but lost. In
2003 the CSU was
Re-elected as the Bavarian government with an overall majority.
Franz Josef Strauß (
1915 -
1988 ) is seen as having set the ideological basis of the party, although he was too young to be a founding leader of the party, which began as a continuation of the Weimar-era
Bavarian People's Party .
