The Monarchy of Germany was the system of government in which a hereditary monarch was the sovereign of the German Empire from 1871 to 1918.

Prince Wilhelm Friedrich Franz Joseph Christian Olaf of Prussia was the eldest child of Wilhelm, German Crown Prince, and Duchess Cecilie of Mecklenburg-Schwerin. At his birth, he was second in line to the German throne and was expected to succeed to the throne after the deaths of his grandfather, Emperor Wilhelm II, and his father, Crown Prince Wilhelm. Both, however, outlived him.
