Gustav III of Sweden

Gustav III (24 January [O.S. 13 January] 1746 – 29 March 1792), also called Gustavus III, was King of Sweden from 1771 until his assassination in 1792. He was the eldest son of King Adolf Frederick and Queen Louisa Ulrika of Sweden.

Gustav was a vocal opponent of what he saw as the abuse of political privileges seized by the nobility since the death of King Charles XII in the Great Northern War. Seizing power from the government in a coup d'état, called the Swedish Revolution, in 1772 that ended the Age of Liberty, he initiated a campaign to restore a measure of royal autocracy. This was completed by the Union and Security Act of 1789, which swept away most of the powers exercised by the Swedish Riksdag of the Estates during the Age of Liberty, but at the same time, it opened up the government for all citizens, thereby breaking the privileges of the nobility.

A believer in enlightened absolutism, Gustav spent considerable public funds on cultural ventures, which were controversial among his critics, as well as military attempts to seize Norway with Russian aid, then a series of attempts to re-capture the Swedish Baltic dominions lost during the Great Northern War through the failed war with Russia. Nonetheless, his successful leadership in the Battle of Svensksund averted a complete military defeat and signified that Swedish military might was to be countenanced after its major defeats earlier in the century.

An admirer of Voltaire, Gustav legalised Catholic and Jewish presence in Sweden, and enacted wide-ranging reforms aimed at economic liberalism, social reform and the restriction, in many cases, of torture and capital punishment. The much-praised Freedom of the Press Act of 1766 was severely curtailed, however, by amendments in 1774 and 1792, effectively extinguishing independent media.

Following the uprising against the French monarchy in 1789, Gustav pursued an alliance of princes aimed at crushing the insurrection and re-instating his French counterpart, King Louis XVI, offering Swedish military assistance as well as his leadership.
