With the unification of Germany and establishment of the German Empire in 1871, the Confederation evolved into a German nation-state and its leader became known as the chancellor of Germany. Originally, the chancellor was only responsible to the emperor. This changed with the constitutional reform in 1918, when the Parliament was given the right to dismiss the chancellor. Under the 1919 Weimar Constitution the chancellors were appointed by the directly elected president, but were responsible to Parliament.\n"
