Paul Ludwig Hans Anton von Beneckendorff und von Hindenburg (pronounced [pal lutv hans anton fn bnkdf nt fn hndnbk] (listen); abbreviated pronounced [pal fn hndnbk] (listen); 2 October 1847 2 August 1934) was a German Field Marshal and statesman who led the Imperial German Army during World War I and later became President of Germany from 1925 until his death in 1934. During his presidency, he played a key role in the Nazi seizure of power in January 1933 when, under pressure from advisers, he appointed Adolf Hitler as Chancellor of Germany.

Paul von Hindenburg was born on 2 October 1847 to a family of minor Prussian nobility in Posen. Upon completing his education as a cadet, he enlisted in the Third Regiment of Foot Guards as a second lieutenant. He then saw combat during the Austro-Prussian and Franco-Prussian wars. In 1873, he was admitted to the prestigious Kriegsakademie in Berlin, where he studied for three years before being appointed to the Army's General Staff Corps. Later in 1885, he was promoted to the rank of major and became a member of the Great General Staff. Following a five-year teaching stint at the Kriegsakademie, Hindenburg steadily rose through the army's ranks to become a lieutenant-general by 1900. Around the time of his promotion to General of the Infantry in 1905, Count Alfred von Schlieffen recommended that he succeed him as Chief of the Great General Staff but the post ultimately went to Helmuth von Moltke in January 1906. In 1911, Hindenburg announced his retirement from the military.

Following World War I's outbreak in July 1914, he was recalled to military service and quickly achieved fame on the Eastern Front as the victor of Tannenberg. Subsequently, he oversaw a crushing series of victories against the Russians that made him a national hero and the center of a massive personality cult. By 1916, Hindenburg's popularity had risen to the point that he replaced General Erich von Falkenhayn as Chief of the Great General Staff. Thereafter, he and his deputy, General Erich Ludendorff, exploited Emperor Wilhelm II's broad delegation of power to the German Army to establish a de facto military dictatorship that dominated national policy for the rest of the war. Under their leadership, Germany secured Russia's defeat in the east and achieved advances on the Western Front deeper than any seen since the conflict's outbreak. However, by the end of 1918, all improvements in Germany's fortunes were reversed after the German Army was decisively defeated in the Second Battle of the Marne and the Allies' Hundred Days Offensive. Upon his country's capitulation to the Allies in the November 1918 armistice, Hindenburg stepped down as Germany's commander-in-chief before retiring once again from military service in 1919.

In 1925, Hindenburg returned to public life to become the second elected president of the German Weimar Republic. While he was personally opposed to Adolf Hitler and his Nazi Party, he nonetheless played a major role in the political instability that resulted in their rise to power. Upon twice dissolving the Reichstag in 1932, Hindenburg ultimately agreed to appoint Hitler as Chancellor of Germany in January 1933 when the Nazis won a plurality in the November elections. In response to the Reichstag Fire allegedly committed by Marinus van der Lubbe, he approved the Reichstag Fire Decree in February 1933 which suspended various civil liberties. Later in March, he signed the Enabling Act of 1933 which gave the Nazi regime emergency powers. After Hindenburg died the following year, Hitler combined the presidency with his office as chancellor before proceeding to declare himself Fhrer und Reichskanzler des deutschen Volkes (lit.'Leader and Reich Chancellor of the German People') and transformed Germany into a totalitarian state.

The 1932 Prussian coup d'état or Preußenschlag (German pronunciation: [ˈpʁɔʏsənˌʃlaːk]) took place on July 20, 1932, when Reich President Paul von Hindenburg, at the request of Franz von Papen, then Reich Chancellor of Germany, invoked Article 48 of the Weimar Constitution to replace the legal government of the Free State of Prussia by von Papen as Reich Commissioner. A second decree the same day transferred executive power in Prussia to the Reich Minister of the Armed Forces Kurt von Schleicher and restricted fundamental rights.

Papen had two rationales for the coup. One was that the 1932 Prussian Reichstag election had left a divided parliament with no viable possibilities for a coalition. This led to a caretaker government under the coalition that had held power before the election. The second and major rationale was that in parts of Prussia there were violent street demonstrations and clashes taking place that Papen said the caretaker government could not control.

The coup had the effect of weakening the federalist constitution of the Weimar Republic and thus facilitating the centralization of the Reich under Adolf Hitler after he came to power in January 1933. The immediate result, however, was elimination of the last resistance in Prussia to Papen's attempt to establish a ‘New State’, essentially a precursor to a restored monarchy. Contrary to Papen's intent, the move ultimately had the effect of easing Hitler's path to power.
