Prince Adolf of Schaumburg-Lippe

Prince Adolf of Schaumburg-Lippe (20 July 1859 – 9 July 1916) was the regent of the Principality of Lippe from 1895 till 1897.

Born at Bückeburg Palace (German: Schloss Bückeburg) in Bückeburg the seventh child of Adolf I, Prince of Schaumburg-Lippe (1817–1893) and Princess Hermine of Waldeck and Pyrmont (1827–1910).

Following the death of Prince Woldemar on the 20 March 1895 and the ascension of Woldemar's brother Alexander, Adolf was appointed to act as regent of Lippe due to Prince Alexander being unable to rule due to a mental illness. He continued to act as regent until 1897 when he was replaced by Count Ernst of Lippe-Biesterfeld.

Prince Adolf was married on the 19 November 1890 in Berlin to Princess Viktoria of Prussia. She was a daughter of Frederick III, German Emperor, and as such Adolf was a brother-in-law to the last German Emperor, Wilhelm II. The wedding was attended by the Emperor Wilhelm, along with his wife Augusta Viktoria of Schleswig-Holstein and Victoria's mother, the widowed Empress Victoria. As Princess Victoria's mother was a member of the British royal family, many of her relatives also attended, including Princess Christian of Schleswig-Holstein. After the ceremony, the couple held a banquet, at which Emperor Wilhelm feelingly assured the pair of "his protection and friendly care".

The marriage was childless, though Princess Viktoria had a miscarriage within the first few months of marriage.
