Baden-Baden is believed to have been established by the Roman Emperor Hadrian (although we are not exactly sure of the exact date). It was originally known as Aurelia Aquensis. It was renamed Baden in the Middle Ages. It only got the second Baden attached to its name in 1931, to distinguish it from other towns also called Baden, which means "baths".
Since the 19th century Baden-Baden has been a watering hole for German celebrities. The town is one of the few places in Germany with a casino.
