Kings of Prussia
Extracted from the Wikipedia article List of Prussian monarchs.
In 1871, in the aftermath of the Franco-Prussian War, the German Empire was formed, and the King of Prussia, Wilhelm I was crowned German Emperor. From that point forward, though the Kingdom of Prussia retained its status as a constituent state of the empire (by far the largest and most powerful), all subsequent Kings of Prussia also served as German Emperor, and that title took precedence.
