Charles VI vs Hans-Adam II of Liechtenstein

Charles VI issued the Pragmatic Sanction, a legal instrument to ensure that the Habsburg hereditary lands could be inherited by a female heir (his daughter Maria Theresa) in the absence of a male son. He spent decades securing recognition from European powers, but it failed to prevent the War of the Austrian Succession.

Charles VI's forces, after a disastrous war with the Ottoman Empire, signed the Treaty of Belgrade. The treaty ceded Belgrade and northern Serbia to the Ottomans, reversing the gains of the Treaty of Passarowitz and weakening Habsburg influence in the Balkans.

Charles VI's death in 1740 triggered the War of the Austrian Succession, as Prussia, France, and Bavaria challenged Maria Theresa's inheritance. The war, lasting until 1748, resulted in the loss of Silesia to Prussia but confirmed Maria Theresa's rule in most Habsburg lands.

Hans-Adam II became Prince of Liechtenstein on November 13, 1989, following the death of his father, Prince Franz Joseph II. He inherited a constitutional monarchy with significant powers, including the ability to veto legislation and dissolve parliament.

Under Hans-Adam II's reign, Liechtenstein transformed into a major financial center, leveraging low taxes and banking secrecy. He oversaw the modernization of the economy, including accession to the European Economic Area in 1995, boosting prosperity but also attracting international scrutiny over tax evasion.

Hans-Adam II pushed through a constitutional reform in a 2003 referendum, expanding his powers to include the right to dismiss the government, veto laws, and appoint judges. The reform was controversial, with critics calling it a step toward absolutism, but it passed with 64% support.

On August 15, 2004, Hans-Adam II transferred the day-to-day executive powers to his son, Hereditary Prince Alois, while retaining the role of head of state. This move was part of a planned succession and allowed Alois to gain experience in governance.
