Chancellor of Germany (1949–present) German chancellor until the end of the Holy Roman Empire in 1806 while the Archbishop of Cologne was Chancellor of Italy and the Archbishop of Trier of Burgundy. These three Archbishops were also Prince-electors of the empire. Already in medieval times the chancellor had political power like Willigis of Mainz (Archchancellor 975–1011, regent for Otto III 991–994) or Rainald von Dassel (chancellor 1156–1162 and 1166–1167) under Frederick I. The modern office of chancellor was established with the North German Confederation, of which Otto von Bismarck became chancellor of the Confederation (official German title: "Bundeskanzler") in 1867. After unification of Germany
Chancellor of Austria sovereign head of government was the State Chancellor of the Austrian Empire, a position only held by Klemens von Metternich. The office was later renamed to Minister-President of the Austrian Empire and remained from there on until the dissolution of Austria-Hungary. The first head of government after the monarchy was the State Chancellor of German-Austria, an office again only held by one person; Karl Renner. After allied powers declined a union between Austria and Germany, the office was renamed to just State Chancellor of Austria and later changed to Federal Chancellor, which remained the position's final form until present day.
