German Emperor

The German Emperor (German: Deutscher Kaiser, pronounced) was the official title of the head of state and of the German Empire. A specifically chosen term, it was introduced with the 1 January 1871 constitution and lasted until the abdication of Wilhelm II was announced on 9 November 1918. The Holy Roman Emperor is sometimes also called "German Emperor" when the historical context is clear, as derived from the Holy Roman Empire's official name of "Holy Roman Empire of the German Nation" from 1512.

Following the revolution of 1918, the head of state was the president of the Reich (German: Reichspräsident), beginning with Friedrich Ebert.
