Angela Dorothea Merkel (née Kasner; born 17 July 1954) is a German former politician and scientist who served as Chancellor of Germany from 2005 to 2021. A member of the Christian Democratic Union (CDU), she previously served as Leader of the Opposition from 2002 to 2005 and as Leader of the Christian Democratic Union from 2000 to 2018. Merkel was the first female chancellor of Germany. During her tenure as Chancellor, Merkel was frequently referred to as the de facto leader of the European Union (EU), the most powerful woman in the world, and since 2016 the leader of the free world. Merkel was born in Hamburg in then-West Germany, moving to East Germany as an infant when her father, a Lutheran clergyman, received a pastorate in Perleberg. She obtained a doctorate in quantum chemistry in 1986 and worked as a research scientist until 1989. Merkel entered politics in the wake of the Revolutions of 1989, briefly serving as deputy spokeswoman for the first democratically elected Government of East Germany led by Lothar de Maizière. Following German reunification in 1990, Merkel was elected to the Bundestag for the state of Mecklenburg-Vorpommern. As the protégée of Chancellor Helmut Kohl, Merkel was appointed as Minister for Women and Youth in 1991, later becoming Minister for the Environment, Nature Conservation and Nuclear Safety in 1994. After the CDU lost the 1998 federal election, Merkel was elected CDU General Secretary, before becoming the party's first female leader and the first female Leader of the Opposition two years later, in the aftermath of a donations scandal that toppled Wolfgang Schäuble.
