Founded in 1945 as an interdenominational Christian party, the CDU effectively succeeded the pre-war Catholic Centre Party, with many former members joining the party, including its first leader Konrad Adenauer. The party also included politicians of other backgrounds, including liberals and conservatives. As a result, the party claims to represent "Christian-social, liberal and conservative" elements. The CDU is generally pro-European in outlook. Black is the party's customary colour. Other colours include red for the logo, orange for the flag, and black-red-gold for the corporate design.
