The Politics of Bavaria takes place within a framework of a federal parliamentary representative democratic republic, where the Federal Government of Germany exercises sovereign rights with certain powers reserved to the states of Germany including Bavaria. The state has a multi-party system where the two main parties are the rightist Christian Social Union of Bavaria (CSU) and the leftist Social Democratic Party of Germany (SPD).
Bavaria has a unicameral Landtag, or state parliament, elected by universal suffrage. Until December 1999, there was also a Senat, or Senate, whose members were chosen by social and economic groups in Bavaria, but following a referendum in 1998, this institution was abolished. The head of government is the Minister-President.
Bavaria has long been a bastion of conservative politics in Germany, with the Christian Social Union having almost a monopoly on power since its inception in 1946. Every Minister-President since 1957 has been a member of this party.
In 1995 the Bavarians decided to introduce direct democracy on the local level in a referendum. This was initiated bottom-up by an association called Mehr Demokratie (More Democracy). This is a grass-roots organization which campaigns for the right to citizen-initiated referendums. In 1997 the Bavarian Supreme Court aggravated the regulations considerably (e.g. by introducing a turn-out quorum). Nevertheless, Bavaria has the most advanced regulations on local direct democracy in Germany. This has led to a spirited citizens’ participation in communal and municipal affairs – 835 referendums took place from 1995 through 2005.
