She previously served as Leader of the Opposition from 2002 to 2005 and as Leader of the Christian Democratic Union from 2000 to 2018. During her chancellorship, Merkel was frequently referred to as the de facto leader of the European Union (EU) and the most powerful woman in the world. Beginning in 2016, she was often described as the leader of the free world.

Merkel was born in Hamburg in West Germany. Her family moved to East Germany when she was an infant. Merkel obtained a doctorate in quantum chemistry in 1986 and worked as a research scientist until 1989. She then 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.
