Hans-Adam II (Johannes Adam Ferdinand Alois Josef Maria Marco d'Aviano Pius; born 14 February 1945) is the Prince of Liechtenstein, reigning since 1989. As a member of the Liechtenstein princely family, he also holds the title of Duke of Troppau and Jägerndorf and Count of Rietberg.
The eldest child of Prince Franz Joseph II and Countess Georgina von Wilczek, Hans-Adam was educated at Schottengymnasium in Austria and in Lyceum Alpinum Zuoz in Switzerland. He then worked as a bank trainee in London before enrolling at the University of St. Gallen to study business administration, where Hans-Adam graduated with a licentiate in 1969. In 1984, Prince Franz Joseph handed over power and everyday duties of the monarch to Hans-Adam, with Hans-Adam thus becoming regent, while his father remained monarch. Following his father's death in 1989, Hans-Adam ascended to the throne.
In 2004, similar to his father's example, Hans-Adam also made his eldest son hereditary prince Alois the country's regent, while remaining its monarch. Since the death of Harald V of Norway in August 2026, Hans-Adam has been Europe's oldest reigning monarch.
Hans-Adam II was born on 14 February 1945 in Zürich, Switzerland, as the eldest son of Prince Franz Joseph II and Princess Gina of Liechtenstein, with his godfather being Pope Pius XII. His father had succeeded as Prince of Liechtenstein in 1938 upon the death of his childless grand-uncle, Prince Franz I, and Hans-Adam was thus hereditary prince from birth.
In 1956, he entered the Schottengymnasium in Vienna. In 1960, he transferred to the Lyceum Alpinium Zuoz in Switzerland, earning a Swiss Matura and a German Abitur in 1965. 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. He is fluent in English and French in addition to his native German.
In 1984, Prince Franz Joseph II, while legally remaining head of state and retaining the title of sovereign prince, formally handed the power of making day-to-day governmental decisions to his eldest son as a way of beginning a dynastic transition to a new generation. Hans-Adam formally succeeded as Prince of Liechtenstein upon the death of his father on 13 November 1989.
A referendum to adopt Hans-Adam's revision of the Constitution of Liechtenstein to expand his powers passed in 2003. The prince had threatened to abdicate and leave the country if the referendum did not result in his favour.
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. Legally, Hans-Adam remains the head of state. Hans-Adam's father Franz Joseph II had similarly done so for him on 26 August 1984.
In a July 2012 referendum, the people of Liechtenstein overwhelmingly rejected a proposal to curtail the political power of the princely family. A few days before the vote, Hereditary Prince Alois announced he would veto any relaxing of the ban on abortion, also up for referendum. Seventy-six percent of those voting in the first referendum supported Alois' power to veto the outcome of future referendums. Legislators, who serve on a part-time basis, rose in the hereditary prince's defence on 23 May, voting 18 to 7 against the citizens' initiative.
Throughout his reign, Hans-Adam has been a prominent proponent of strengthening Liechtenstein's economic and political independence from Switzerland, with which Liechtenstein has been in a customs union since 1924. In a speech from 1970 nicknamed the "backpack speech", Hans-Adam declared his intentions to push for an independent Liechtenstein foreign policy. He was a major proponent of Liechtenstein joining the United Nations, which the country successfully did in 1990.
Hans-Adam instigated the 1992 Liechtenstein constitutional crisis by calling for a referendum regarding Liechtenstein's accession to the European Economic Area to be held in advance of the corresponding one in Switzerland, against the wishes of both the government and the Landtag of Liechtenstein. On 28 October 1992, he threatened to dissolve the Landtag and dismiss the Prime Minister of Liechtenstein, Hans Brunhart, over the dispute and appoint an acting prime minister in his place. In response, approximately 2,000 people demonstrated in front of the government house in Vaduz. On the same day, the government and Hans-Adam II negotiated and came to an agreement that scheduled the referendum after the corresponding one in Switzerland, though notably it affirmed that Liechtenstein would commit to agreements with the EEA despite the result in Switzerland. The event forced the customs union between Liechtenstein and Switzerland to be revised to grant Liechtenstein greater freedom in deciding its foreign policy, and Liechtenstein subsequently joined the EEA in 1995.
In 1995, Hans-Adam was the subject of a complaint to the European Convention on Human Rights against the state of Liechtenstein for the violation of freedom of speech and right to an effective remedy. This was prompted by Hans-Adam sending a letter to former Deputy Prime Minister of Liechtenstein Herbert Wille, which stated that he would not appoint Wille to a public office due to him expressing the opinion in a speech that the Liechtenstein state court should hold the final say over the prince regarding disputes with the constitution of Liechtenstein. In 1999, the ECHR ruled that a violation had taken place and the state of Liechtenstein was convicted.
In an interview with Radio Liechtenstein in February 2021, Prince Hans-Adam II expressed his support for same-sex marriage but said he opposed allowing same-sex couples to adopt.
Hans-Adam has written the political treatise The State in the Third Millennium, which was published in late 2009. In it, he argues for the continued importance of the nation-state as a political actor. 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. He also declared his role in a princely family as something that has legitimacy only from the assent of the people. He stated that government should be limited to a small set of tasks and abilities, writing that people "have to free the state from all the unnecessary tasks and burdens with which it has been loaded during the last hundred years, which have distracted it from its two main tasks: maintenance of the rule of law and foreign policy". Hans-Adam is a friend of the German anarcho-capitalist economist Hans-Hermann Hoppe.
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, and in the Encyclopedia Princetoniensis.
Hans-Adam has financed research into UFOs for decades and is said to have a great personal interest in ufology. This became public through the diaries of the well-known ufologist and astronomer Jacques Vallée, whom Hans-Adam had invited to his castle. He also worked with the American businessman Robert Bigelow, who has also financed UFO research. Hans-Adam's interest in the phenomenon is said to have been sparked by a UFO sighting by his aunt in Munich in the 1950s.
Entrepreneurship and personal wealth
Before his accession to the throne, he transformed LGT Bank which is wholly owned by his family, from a small local bank into an internationally operating financial group. As of 2003 he had a family fortune of US$7.6 billion and a personal fortune of about US$4 billion, making him one of the world's richest heads of state, and Europe's wealthiest monarch.
