Hans-Adam II (Johannes Adam Ferdinand Alois Josef Maria Marco d'Aviano Pius; born 14 February 1945) is 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.

[1] He was born on 14 February 1945 in Zürich, Switzerland, as the eldest son of Prince Franz Joseph II and Princess Gina of Liechtenstein,[2] with his godfather being Pope Pius XII.

He then worked as a bank trainee in London before enrolling at the University of St. Gallen to study business administration, graduating with a licentiate in 1969.

[9] On August 15, 2004, Hans-Adam formally handed the power of making day-to-day governmental decisions to his eldest son Hereditary Prince Alois as regent, as a way of beginning a dynastic transition to a new generation.

[11] In a July 2012 referendum, the people of Liechtenstein overwhelmingly rejected a proposal to curtail the political power of the princely family.

As of July 2022, his net worth was estimated by Bloomberg Billionaires Index around US$6.20 billion, making him the 380th richest person on earth.

[citation needed] His successful entrepreneurship allowed him to buy back parts of the family art collection[17] which his father had to sell after World War II due to lack of money after his vast land holdings in Czechoslovakia had been expropriated (measuring 7.5 times the total area of the Principality itself) and after his Austrian properties had become inaccessible until the end of the Soviet occupation in 1955.

He makes the case for democracy as the best form of government, which he sees China and Russia as in transition towards, although the path will be difficult for these nations.

[39] Hans-Adam wrote to the foreword to a Sourcebook, on Self-Determination and Self-Administration, which was edited by Wolfgang F. Danspeckgruber and Arthur Watts (ISBN 1-55587-786-9, 1997), and in the Encyclopedia Princetoniensis.
