Germany's strongest political party, currently headed by Chancellor Angela Merkel, has been in power for most of the time since the end of the Second World War.
The CDU was founded after World War II. Five of the eight chancellors since 1949 came from the CDU. It has 470,000 members and a voter base of Christian and conservative, often elderly, citizens as well as small and medium sized entrepreneurs. In the 2013 general elections, the CDU and its Bavarian CSU sister party won 311 of the 631 available seats.
