How the Christian Democratic Union transformed from a post-war coalition to a conservative vanguard

In short: Founded in 1945 to bridge religious divides, the Christian Democratic Union has dominated German politics for decades. From the pragmatic centrism of Angela Merkel to the traditionalist shift under Friedrich Merz, the party has constantly reinvented its identity to navigate the shifting currents of European history and internal ideological tension.

Established in the immediate aftermath of World War II, the CDU emerged as an interdenominational party intended to unite Catholics and Protestants under a banner of liberal conservatism. By the late 1940s, the party secured the support of Western powers, particularly the United States and the United Kingdom, who viewed its anti-communist stance and commitment to capitalism as a vital bulwark against Soviet influence. Konrad Adenauer, the party's first chairman, cemented this pro-Western orientation, ensuring West Germany's integration into the Western alliance despite internal opposition regarding rearmament and neutrality.

The party's electoral dominance was defined by its ability to adapt, leading the federal government for decades under figures like Adenauer, Helmut Kohl, and Angela Merkel. However, this success often masked deep internal friction. During Merkel’s long tenure, the party adopted more socially liberal positions, including the phase-out of nuclear energy and the suspension of conscription. Critics argued this strategy, dubbed 'asymmetric demobilisation,' blurred the lines between the CDU and its rivals, potentially alienating its conservative base and creating a political vacuum to its right, which the Alternative for Germany (AfD) eventually exploited.

Following a period of leadership instability and electoral setbacks, the party has pivoted under Friedrich Merz. Since assuming the chairmanship in 2022 and the chancellorship in 2025, Merz has steered the CDU toward a more traditional conservative platform. This shift includes explicit opposition to gender-neutral language, a renewed focus on national identity, and a reversal of previous environmental policies, such as the advocacy for nuclear energy. By challenging progressive 'woke' trends and tightening immigration stances, the current CDU seeks to reclaim its core constituency and reassert its identity as the primary force of the German centre-right.
