Question: Federal elections took place on 27 September 2009 to elect the members of the 17th Bundestag (parliament) of Germany, the Christian Democrats previously governed in coalition with the FDP in most of the 1982–1998 governments of which German statesman who served as Chancellor of Germany from 1982 to 1998 (of West Germany 1982–1990 and of the reunited Germany 1990–1998) and as the chairman of the Christian Democratic Union (CDU) from 1973 to 1998?
Context: Helmut Josef Michael Kohl (] ; 3 April 1930 – 16 June 2017) was a German statesman who served as Chancellor of Germany from 1982 to 1998 (of West Germany 1982–1990 and of the reunited Germany 1990–1998) and as the chairman of the Christian Democratic Union (CDU) from 1973 to 1998.  From 1969 to 1976, Kohl was minister president of the state Rhineland-Palatinate.  Kohl chaired the Group of Seven in 1985 and 1992. Hamburg Eimsbüttel is one of the 299 single member constituencies used for the German parliament, the Bundestag.  Located in north west Hamburg, the district was created for the 1949 election, the first election in West Germany after World War II.  With the exception of the 1953 election, which was won by the German Party, all elections until 2009, were won by the Social Democratic Party of Germany (SPD).  However at the 2009 election their vote share almost halved and they finished in third place.  As a result, despite a decrease in their vote share, the Christian Democratic Union (CDU) gained the seat for the first time.  The Greens also had their third best electoral district result (after Berlin Friedrichshain-Kreuzberg – Prenzlauer Berg East and Stuttgart I.)  At the 2013 election the Green's vote share halved, with much of their vote being gained by the SPD.  As a result, despite an increase in his vote shate, the incumbent member of the Bundestag, Rüdiger Kruse of the CDU, lost to the SPD candidate Niels Annen, who had previously represented the district from 2005 to 2009. Konrad Hermann Joseph Adenauer (] ; 5 January 1876 – 19 April 1967) was a German statesman who served as the first post-war Chancellor of the Federal Republic of Germany (West Germany) from 1949 to 1963.  He led his country from the ruins of World War II to a productive and prosperous nation that forged close relations with France, the United Kingdom and the United States.  During his years in power West Germany achieved democracy, stability, international respect and economic prosperity (""Wirtschaftswunder"", German for "economic miracle").  He was the first leader of the Christian Democratic Union (CDU), a Christian Democratic party that under his leadership became one of the most influential parties in the country. State elections took place in Saxony on 30 August 2009, the same day as the Saarland and Thuringia state elections.  The election results decided control of the Landtag of Saxony (Saxony's parliament).  Minister-President Stanislaw Tillich's Christian Democratic Union (CDU) won enough seats in combination with their preferred partners, the Free Democratic Party (FDP) to enter into a coalition government, supplanting the grand coalition with the Social Democratic Party (SPD). Merkel's first cabinet led the government of Germany from 22 November 2005 to 27 October 2009 throughout the 16th "Bundestag".  Led by Christian Democrat Angela Merkel, the first female chancellor in German history, the cabinet was supported by a grand coalition between the Christian Democratic Union (CDU), Christian Social Union of Bavaria (CSU), and the Social Democratic Party of Germany (SPD).  It followed the Second Schröder cabinet.  It ceased to function after the formation of Second Merkel cabinet, which was created after the 2009 federal elections, and was later sworn in on 28 October 2009. Federal elections were held in Germany on 2 December 1990 to elect the members of the 12th Bundestag.  They were the first competitive and universal all-German election since the elections of March 1933 which cemented Adolf Hitler's power.  The result was a comprehensive victory for the governing coalition of the Christian Democratic Union/Christian Social Union and the Free Democratic Party, which was reelected to a third term. The second Merkel cabinet was the Government of Germany during the 17th legislative session of the Bundestag following the 2009 federal election, and left office on 17 December 2013.  It was preceded in office by the first Merkel cabinet.  Led by Chancellor Angela Merkel (the first female chancellor in German history), it was supported by a coalition of the Christian Democratic Union (CDU), the Christian Social Union of Bavaria (CSU), and the Free Democratic Party (FDP). Federal elections took place on 27 September 2009 to elect the members of the 17th Bundestag (parliament) of Germany.  Preliminary results showed that the Christian Democratic Union (CDU), its Bavarian sister party, the Christian Social Union (CSU), and the Free Democratic Party (FDP) won the election, and the three parties announced their intention to form a new centre-right government with Angela Merkel as Chancellor.  Their main opponent, Frank-Walter Steinmeier's Social Democratic Party (SPD), conceded defeat.  The Christian Democrats previously governed in coalition with the FDP in most of the 1949–1966 governments of Konrad Adenauer and Ludwig Erhard and the 1982–1998 governments of Helmut Kohl. The 2013 German federal election was held on Sunday, 22 September, to elect the members of the 18th Bundestag of Germany.  At stake were all 598 seats to the Bundestag, plus 33 overhang seats determined thereafter.  The Christian Democratic Union/Christian Social Union (CDU/CSU) of Chancellor Angela Merkel won their best result since 1990, with nearly 42% of the vote and nearly 50% of the seats (five short for an overall majority).  However, their coalition partner, the Free Democrats (FDP), failed to meet the 5% vote threshold in what was their worst showing ever in a federal election, thus denying them seats in the Bundestag for the first time in their history. Julia Klöckner (born 16 December 1972) is a German politician and member of the Christian Democratic Union or CDU.  She first became known in 1995 when she was chosen as the German Wine Queen ("Deutsche Weinkönigin").  From 2002 to 2011 she was a member of parliament in the German Bundestag and, from 2009 to February 2011, she was a parliamentary undersecretary in the Federal Ministry of Food, Agriculture and Consumer Protection.  Since 25 September 2010 she has chaired the Rhineland-Palatinate CDU party and, since March 2011, the CDU faction in the Landtag of Rhineland-Palatinate, the state parliament.  She is also leading candidate of the CDU in the 2016 Rhineland-Palatinate state elections.  Since 15 November 2010 she has been on the CDU's national "Präsidium" (executive committee) and on 4 December 2012 she was elected as one of the Deputy Federal Chairmen and -women of the CDU.  Recently, she has been mentioned by the media a possible successor to Angela Merkel, alongside Ursula von der Leyen.
