Joachim-Friedrich Martin Josef Merz (born 11 November 1955) is a German politician serving as Chancellor of Germany since 6 May 2025. He has also served as Leader of the Christian Democratic Union (CDU) since January 2022, leading the CDU/CSU (Union) parliamentary group as Leader of the Opposition in the Bundestag from February 2022 to May 2025.
Merz was born in Brilon in the state of North Rhine-Westphalia in West Germany. He joined the Young Union in 1972. After finishing law school in 1985, Merz worked as a judge and corporate lawyer before entering full-time politics in 1989 when he was elected to the European Parliament. As a young politician in the 1970s and 1980s, Merz was a staunch supporter of anti-communism, the dominant political doctrine of West Germany and a core tenet of the CDU. He is seen as a representative of the traditional establishment conservative and pro-business wings of the CDU. His book Mehr Kapitalismus wagen (Venturing More Capitalism) advocates economic liberalism. After serving one term he was elected to the Bundestag, where he established himself as the leading financial policy expert in the CDU. He was elected chairman of the CDU/CSU parliamentary group in 2000, the same year as Angela Merkel was elected chairwoman of the CDU, and at the time they were chief rivals for the leadership of the party, which led the opposition together with CSU.
