Paul von Hindenburg defeats Wilhelm Marx in the second round of the German presidential election to become the first directly elected head of state of the Weimar Republic.

Paul Ludwig Hans Anton von Beneckendorff und von Hindenburg was a German military and political leader who led the Imperial German Army during World War I and later became President of Germany from 1925 until his death in 1934. He played a key role in the Nazi seizure of power in 1933 when he appointed Adolf Hitler as Chancellor of Germany.

Wilhelm Marx was a German judge, lawyer, and politician who twice served as chancellor of Germany during the Weimar Republic, from 1923 to 1925 and again from 1926 to 1928. He also briefly held the position of Minister-President of Prussia in 1925. A leading figure in the Centre Party, he served as its chairman from 1922 to 1928. With a total tenure of three years and 73 days, he was the longest-serving chancellor of the Weimar Republic.

Presidential elections were held in Germany on 29 March 1925, with a runoff on 26 April. They were the first direct elections to the office of President of the Reich, Germany's head of state during the 1919–33 Weimar Republic. The first President, Friedrich Ebert, who had died on 28 February 1925, had been elected indirectly, by the National Assembly, but the Weimar Constitution required that his successor be elected by the "whole German people". Paul von Hindenburg was elected as the second president of Germany in the second round of voting.

A head of state is the public persona of a sovereign state. The name given to the office of head of state depends on the country's form of government and any separation of powers; the powers of the office in each country range from being also the head of government to being little more than a ceremonial figurehead.
