The CDU/CSU, often known as the Union, is a political entity in Germany formed by the partnership of two conservative parties: the Christian Democratic Union (CDU) and the Christian Social Union (CSU). The CDU operates in all German states except Bavaria, where the CSU operates exclusively. Together, these sister parties work to represent and promote conservative and Christian-social values within the German political system.

Meaning and history

The CDU was founded in 1945 by Konrad Adenauer and others as a response to the need for a new political force in post-war Germany, while the CSU was established in the same year under the leadership of Josef Müller. These foundations aimed to create a broad, interdenominational gathering against the backdrop of the destruction of the Third Reich, focusing on Christian-social, liberal, and conservative values.

Throughout the decades, the CDU/CSU has achieved significant milestones in German politics. They have been pivotal in the economic recovery of Germany, the reunification process, and the establishment of Germany as a key player in European and global politics. Under the leadership of figures like Konrad Adenauer, Helmut Kohl, and Angela Merkel, the Union has held the chancellorship for numerous terms, significantly shaping the policy landscape in Germany.

Today, the CDU/CSU continues to be a major force in German politics. While it faces challenges like the rise of alternative political movements and shifts in public opinion, its role in shaping Germany’s response to international issues, economic policies, and social integration is pivotal. The party aims to address contemporary challenges while maintaining its commitment to its foundational values.

A key feature of the logo is the stylized element between “CDU” and “CSU,” which consists of three dynamic, curved stripes. These stripes create a sense of movement and forward momentum, symbolizing progress and innovation. The integration of this element not only connects the two party names but also emphasizes their collaboration and joint commitment to common goals and policies.

Below the main acronyms, the phrase “Fraktion im Deutschen Bundestag” is written in a refined serif typeface, adding a touch of formality and emphasizing the parties’ role within the German federal parliament. The use of navy blue for both the text and the dynamic stripes ensures a unified and harmonious appearance, reinforcing the idea of a strong alliance.
