Chancellor of Germany was usually held by Archbishops of Mainz. The title was, at times, used in several states of German-speaking Europe. The modern office of chancellor was established with the North German Confederation, of which Otto von Bismarck became "Bundeskanzler" (meaning "Federal Chancellor") in 1867. With the enlargement of this federal state to the German Empire in 1871, the title was renamed to "Reichskanzler" (meaning "Chancellor of the Realm"). With Germany's constitution of 1949, the title of "Bundeskanzler" was revived. During the various eras, the role of the chancellor has varied. From 1867 to 1918, the chancellor was the only responsible minister
Vice-Chancellor of Germany Since 1966, it has often been held by the Minister of Foreign Affairs. It is the Chancellor who chooses which minister serves as Vice Chancellor. Since coalition governments are common in German politics, the Vice Chancellor is in most cases a minister of the junior coalition partner, often the respective party leader. In case of the Chancellor's absence, the Vice Chancellor acts in his or her place, for instance by heading Cabinet meetings. The Vice Chancellor will not automatically become Chancellor for the rest of the term if the Chancellor dies or becomes unable to fulfill his or her duties
