The Battenberg family is a German noble family that originated in the 19th century. They are known for their connections to various European royal families, particularly through marriage. The family name is derived from the town of Battenberg in Hesse, Germany. In the early 20th century, the family changed their 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 born a Prince of Greece and Denmark and was a descendant of the Battenberg lineage.
