The Chancellor of Germany is the head of government of Germany. The official title in German is Bundeskanzler(-in) (literally, Federal Chancellor), often shortened to Kanzler(-in).

In German politics the Chancellor is equivalent to that of a Prime Minister in many other countries. The German term directly equivalent of Prime Minister, Ministerpräsident, is used for the heads of government of most German states (referred to in German as Länder, literally "countries") as well as foreign countries.

The current Chancellor is Angela Merkel, who was re-elected in 2009 after her first election in 2005. She is the first female Chancellor. In German she is thus known as Bundeskanzlerin. That particular word was never used officially before Merkel, but it is a grammatically regular formation of a noun denoting a female.

The modern office of Chancellor evolved from the position created for Otto von Bismarck in the North German Confederation in 1867; the Confederation evolved into a German nation-state with the 1871 Unification of Germany. The role of the Chancellor has varied greatly throughout Germany's modern history. Today, the Chancellor is widely considered to be the country's effective leader.

Lieutenant-Colonel Franz Joseph Hermann Michael Maria von Papen zu Köningen ( listen (help·info)) (29 October 1879 – 2 May 1969) was a German nobleman, General Staff officer and right-wing politician. He served as as Chancellor of Germany in 1932 and as Vice-Chancellor under Adolf Hitler in 1933–1934. He belonged to the group of close advisers to President Paul von Hindenburg in the late Weimar Republic. It was largely Papen, believing that Hitler could be controlled once he was in the government, who persuaded Hindenburg to appoint Hitler as Chancellor in a cabinet not under Nazi Party domination. However, Papen and his allies were quickly marginalized by Hitler and he left the government after the Night of the Long Knives, during which some of his confidants were killed by the Nazis.

Born to a wealthy and noble Catholic family in Werl, Province of Westphalia, son of Friedrich von Papen zu Köningen (1839 – 1906) and his wife Anna Laura von Steffens (1852 – 1939), Papen was educated as an officer, including a period as a military attendant in the Kaiser's Palace, before joining the German General Staff in March 1913. He entered diplomatic service in December 1913 as a military attaché to the German ambassador in the United States. He travelled to Mexico (to which he was also accredited) in early 1914 and observed the Mexican Revolution, returning to Washington, D.C. on the outbreak of World War I in August 1914. He married Martha von Boch-Galhau (1880 – 1961) on 3 May 1905.

Otto Eduard Leopold, Prince of Bismarck, Duke of Lauenburg (1 April 1815 – 30 July 1898), simply known as Otto von Bismarck, was a conservative German statesman who dominated European affairs from the 1860s to his dismissal in 1890. After a series of short victorious wars he unified numerous German states into a powerful German Empire under Prussian leadership, then created a "balance of power" that preserved peace in Europe from 1871 until 1914.

As Minister President of Prussia 1862–90, Bismarck provoked wars that made Prussia dominant over Austria and France, and lined up the smaller German states behind Prussia. In 1867 he also became Chancellor of the North German Confederation. Bismarck designed and created the German Empire in 1871, becoming its first Chancellor and largely controlling its affairs until he was removed by Kaiser (Emperor) William II in 1890. His diplomacy of Realpolitik and powerful rule gained him the nickname the "Iron Chancellor". As Henry Kissinger has noted, "The man of 'blood and iron' wrote prose of extraordinary directness and lucidity, comparable in distinctiveness to Churchill's use of the English language."
