Anne, Duchess of Brittany, is married to Maximilian I, Holy Roman Emperor by proxy.

Anne of Brittany was reigning Duchess of Brittany from 1488 until her death, and Queen of France from 1491 to 1498 and from 1499 to her death. She was the only woman to have been queen consort of France twice. During the Italian Wars, Anne also became Queen of Naples, from 1501 to 1504, and Duchess of Milan, in 1499–1500 and from 1500 to 1512.

Maximilian I was King of the Romans from 1486 and Holy Roman Emperor from 1508 until his death in 1519. He was never crowned by the Pope, as the journey to Rome was blocked by the Venetians. He proclaimed himself elected emperor in 1508 at Trent, with Pope Julius II later recognizing it. This broke the tradition of requiring a papal coronation for the adoption of the Imperial title. Maximilian was the only surviving son of Frederick III, Holy Roman Emperor, and Eleanor of Portugal. From his coronation as King of the Romans in 1486, he ran a double government, or Doppelregierung with his father until Frederick's death in 1493.

A proxy wedding or proxy marriage is a wedding in which one or both of the individuals being united are not physically present, usually being represented instead by other persons (proxies). If both partners are absent, this is known as a double proxy wedding.
