Heinrich Brüning ( listen (help·info)) (26 November 1885 – 30 March 1970) was Chancellor of Germany from 1930 to 1932, during the Weimar Republic. He was the longest serving Chancellor of the Weimar Republic.

Soon after Brüning took power, he was confronted by an economic crisis caused by the Great Depression. Brüning responded with a tightening of credit and a rollback of all wage and salary increases. These policies made him very unpopular and lost him the support of the Reichstag. During much of Brüning's tenure, he based his administration on presidential emergency decree ("Notverordnung"). He coined the term "authoritative (or authoritarian) democracy" to describe this form of government based on the cooperation of the president and toleration of the parliament.

Brüning remains a controversial figure in German politics. His intentions were to protect the Republican government, but his policies contributed to the gradual demise of the Weimar Republic.

Born in Münster in Westphalia, Brüning lost his father when he was one year old and thus his elder brother Hermann Joseph played a major part in his upbringing. Although brought up as a devout Catholic, Brüning was also influenced by Lutheranism's concept of duty, since the Münster region was home to both Catholics, who formed a majority (especially in the western part) and some Prussian-influenced Protestants.

Paul Ludwig Hans Anton von Beneckendorff und von Hindenburg ( listen (help·info)), known universally as Paul von Hindenburg (German: [ˈpaʊl fɔn ˈhɪndənbʊɐ̯k] ( listen); 2 October 1847 – 2 August 1934) was a Prussian-German field marshal, statesman, and politician, and served as the second President of Germany from 1925 to 1934.

Hindenburg enjoyed a long career in the Prussian Army, retiring in 1911. He was recalled at the outbreak of World War I, and first came to national attention, at the age of 66, as the victor at Tannenberg in 1914. As Germany's Chief of the General Staff from 1916, he and his deputy, Erich Ludendorff, rose in the German public's esteem until Hindenburg came to eclipse the Kaiser himself.^{[citation needed]} Hindenburg retired again in 1919, but returned to public life one more time in 1925 to be elected as the second President of Germany.

Though 84 years old and in poor health, Hindenburg was persuaded to run for re-election in 1932, as he was considered the only candidate who could defeat Adolf Hitler. Hindenburg was re-elected in a runoff. Although he was opposing Hitler, the deteriorating political stability of the Weimar Republic let him play an important role in the Nazi Party's rise to power. He dissolved the parliament twice in 1932 and eventually appointed Hitler as Chancellor in January 1933. In February, he issued the Reichstag Fire Decree which suspended various civil liberties, and in March he signed the Enabling Act, in which the parliament gave Hitler's administration legislative powers. Hindenburg died the following year, after which Hitler declared the office of President vacant and, as "Führer und Reichskanzler", made himself head of state.
