Horst Köhler
Horst Köhler (; born 22 February 1943) is a German politician of the Christian Democratic Union, and served as President of Germany from 2004 to 2010. As the candidate of the two Christian Democratic sister parties, the CDU and the CSU, and the liberal FDP, Köhler was elected to his first five-year term by the Federal Assembly on 23 May 2004 and was subsequently inaugurated on 1 July 2004. He was reelected to a second term on 23 May 2009. Just a year later, on 31 May 2010, he resigned from his office in a controversy over his comment on the role of the German Bundeswehr in light of a visit to the troops in Afghanistan. During his tenure as German President, whose office is mostly concerned with ceremonial matters, Köhler was a highly popular politician, with approval rates above those of both chancellor Schröder and later chancellor Merkel.
