Gerhard Fritz Kurt Schröder (] ; born 7 April 1944) is a German politician, and served as Chancellor of Germany from 1998 to 2005.
 As a member of the Social Democratic Party of Germany (SPD), he led a coalition government of the SPD and the Greens.
 Before becoming a full-time politician, he was a lawyer, and before becoming Chancellor he served as Prime Minister of Lower Saxony (1990–1998).
 Following the 2005 federal election, which his party lost, after three weeks of negotiations he stood down as Chancellor in favour of Angela Merkel of the rival Christian Democratic Union.
 He is currently the chairman of the board of Nord Stream AG, after having been hired as a global manager by investment bank Rothschild, and also the chairman of the board of football club Hannover 96.
Adolf Hitler (] ; 20 April 1889 – 30 April 1945) was a German politician who was the leader of the Nazi Party ("Nationalsozialistische Deutsche Arbeiterpartei"; NSDAP), Chancellor of Germany from 1933 to 1945 and Führer ("Leader") of Nazi Germany from 1934 to 1945.
 As dictator, Hitler initiated World War II in Europe with the invasion of Poland in September 1939, and was central to the Holocaust.
The Nero Decree (German: "Nerobefehl" ) was issued by Adolf Hitler on March 19, 1945 ordering the destruction of German infrastructure to prevent their use by Allied forces as they penetrated deep within Germany.
 It was officially titled Demolitions on Reich Territory Decree ("Befehl betreffend Zerstörungsmaßnahmen im Reichsgebiet") and has subsequently become known as the Nero Decree, after the Roman Emperor Nero, who supposedly engineered the Great Fire of Rome in 64 AD.
 The decree was deliberately disobeyed by Albert Speer.
The Reichstag Fire Decree (German: "Reichstagsbrandverordnung" ) is the common name of the Decree of the Reich President for the Protection of People and State (German: "Verordnung des Reichspräsidenten zum Schutz von Volk und Staat" ) issued by German President Paul von Hindenburg on the advice of Chancellor Adolf Hitler on 28 February 1933 in immediate response to the Reichstag fire.
 The decree nullified many of the key civil liberties of German citizens.
 With Nazis in powerful positions in the German government, the decree was used as the legal basis for the imprisonment of anyone considered to be opponents of the Nazis, and to suppress publications not considered "friendly" to the Nazi cause.
 The decree is considered by historians as one of the key steps in the establishment of a one-party Nazi state in Germany.
Egon Franke (11 April 1913 – 26 April 1995) was a German politician and a member of the Social Democratic Party of Germany.
 He was Federal Minister for Intra-German Relations from 1969 to 1982 and Vice Chancellor of West Germany in 1982.
 With a tenure of 14 days he was the Vice Chancellor with the shortest time in office.
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.

 During that period he promoted the concept of the social market economy ("soziale Marktwirtschaft"), on which Germany's economic policy in the 21st century continues to be based.
 In his tenure as chancellor, however, Erhard failed to win confidence in his handling of a budget deficit and his direction of foreign policy, and his popularity waned.
