Norway's Princess Märtha Louise — the only daughter and oldest child of King Harald V and Queen Sonja — relinquished her royal privileges in 2002 in order to live off her own income. Soon after marrying late author Ari Behn, Märtha began her own business, and her title of "Her Royal Highness" was replaced with "Her Highness," so she could have more freedom to work away from her constitutional role as a princess.
