Minister for Women and Youth, 1991–1994 In the German federal election of 1990, the first to be held following reunification, Merkel successfully stood for election to the Bundestag in the parliamentary constituency of Stralsund – Nordvorpommern – Rügen in north Mecklenburg-Vorpommern.

Merkel oversaw a string of CDU election victories in six out of seven state elections in 1999, breaking the long-standing SPD-Green hold on the Bundesrat. Following a party funding scandal that compromised many leading figures of the CDU – including Kohl himself and his successor as CDU Leader, Wolfgang Schäuble – Merkel criticised her former mentor publicly and advocated a fresh start for the party without him. Chairperson of the CDU, 2000–2018 She was subsequently elected to replace Schäuble, becoming the first female leader of a
