The House of Battenberg is a German noble family that originated in the 19th century. It was founded by Prince Alexander of Hesse and by Rhine, who adopted the name Battenberg after the town of Battenberg in Hesse. The family became prominent in European royalty, with members marrying into various royal families across the continent. In the early 20th century, the family changed its name to Mountbatten in Britain due to anti-German sentiment during World War I. Notable members include Louis Mountbatten, the last Viceroy of India, and Prince Philip, Duke of Edinburgh, who was a descendant of the House of Battenberg.
