Hans-Adam II, Prince of Liechtenstein
Hans-Adam II (Johannes Adam Ferdinand Alois Josef Maria Marco d'Aviano Pius; born 14 February 1945) is the reigning Prince of Liechtenstein, since 1989. He is the son of Prince Franz Joseph II and his wife, Countess Georgina von Wilczek. He also bears the titles Duke of Troppau and Jägerndorf, and Count of Rietberg. Under his reign, a 2003 constitutional referendum expanded the powers of the Prince of Liechtenstein. In 2004, Hans-Adam transferred day-to-day governmental duties to his eldest son Hereditary Prince Alois as regent, like his father had granted him in 1984 to prepare him for the role.
