EuroMillions kicked off on 7 February 2004, created by France’s Française des Jeux, Spain’s Loterías y Apuestas del Estado, and the UK’s Camelot group (now Allwyn). The first draw was held simply days later, on 13 February, in Paris.
Originally performed solely within the UK, France, and Spain, the lottery rapidly expanded in October 2004 to incorporate Austria, Belgium, Ireland, Luxembourg, Portugal, and Switzerland.
