The place name Orange has a separate etymology. The Roman-Celtic settlement was founded in 36 or 35 BC and originally named Arausio, after a Celtic water god.[5] The Principality of Orange was named for this place and not for the colour. Some time after the sixteenth century, though, the colour orange was adopted as a canting symbol of the House of Orange-Nassau.[6] The colour eventually came to be associated with Protestantism, due to participation by the House of Orange on the Protestant side in the French Wars of Religion and the Dutch Eighty Years' War.[7]
