Profile: The CDU and its Bavarian sister party, the CSU, were established as non-denominational Christian parties directly after the Second World War by members of the civilian resistance to National Socialism. Their core values are rooted in Catholic social doctrine, Conservativism, and commitment to a liberal (social) market economy that is provided with a regulatory framework of rules and laws by the state. The CDU/CSU regards itself as a “catch-all party” that expressly combines many different interests and therefore aims to speak and develop policies on behalf of a very large part of the population.

The CDU runs for election in all Germany’s states apart from Bavaria, where its place is taken by the CSU, which only stands in Bavaria. The two parties are often known colloquially as “the Union”. In the Bundestag they form the CDU/CSU parliamentary group. The “Union” is traditionally the strongest party in Germany and has governed the country the longest in various coalitions.
