List of German monarchs in 1918
The term German Empire (Deutsches Kaiserreich) commonly refers to Germany, from its foundation as a unified nation-state on 18 January 1871, until the abdication of its last Kaiser, Wilhelm II, on November 9, 1918. Germans, when referring to the Reich in this period under the Kaisers, 1871 to 1918, typically use the term Kaiserreich.
|Preceded by||Kingdom of Prussia|

Federal prince (Bundesfürst) was the generic term for the royal heads of state (monarchs) of the various states making up the German Empire. The empire was a federal state, with its constituent states remaining sovereign states. In total, there were 22 federal princes of the German Empire and additionally three republican heads of state and the steward of the imperial territory ruled by Alsace-Lorraine. The states became part of the Kaiserreich by an 1871 treaty. The Kaiser as head of the empire was granted the title German Emperor (the style "Emperor of Germany" being deliberately avoided), and was simultaneously a federal prince as King of Prussia, the sovereign of its largest federal state. Of the princely heads of state, 4 held the title King (König) (the Kings of Prussia, Bavaria, Saxony, and Württemberg), 6 held the title Grand Duke (Großherzog), 5 held the title Duke (Herzog), and 7 held the title Prince (i.e. Sovereign Prince, Fürst).
Following the abdication of Wilhelm II on 9 November 1918 and German Revolution of 1918–19, the German nobility and royalty as legally defined classes were abolished on 11 August 1919 with the promulgation of the Weimar Constitution, under which all Germans were made equal before the law, and the legal rights and privileges, and all following German Houses, titles, insignia and ranks of nobility were abolished.
In addition to the people mentioned on this list, it is also worth mentioning the Grand Duchess of Luxembourg, Marie-Adélaïde, who retained her office during the occupation and abdicated in favor of a younger sister in January 1919. The list also did not mention local rulers in German colonies such as Yuhi V of Rwanda and Mwambutsa IV of Burundi.
