'Gustav IV Adolf' (
November 1,
1778 –
February 7,
1837), was
King of Sweden from
1792 until his abdication in
1809. He was the son of
Gustav III of Sweden and his queen consort
Sophie Magdalena, eldest daughter of
Frederick V of Denmark and his first wife
Louise of Great Britain. He was the last Swedish ruler of Finland.
Early life

'Gustav IV Adolf'
King of Sweden
Gustav Adolf was born in
Stockholm. It was rumored that Gustav Adolf was the biological son of the Nobleman, then Baron and later
Count Adolf Fredrik Munck af Fulkila, though this has never been established. He was raised under the tutelage of his father and the liberal-minded Nils von Rosenstein. Upon Gustav III's assassination in March 1792, Gustav Adolf succeeded to the throne at the age of 14, under the regency of his uncle,
Charles, duke of Södermanland.
In August 1796 his uncle the regent arranged for the young king to visit
St. Petersburg to betroth him to
Catherine the Great's granddaughter,
Grand Duchess Alexandra Pavlovna. However, the whole arrangement foundered on the obstinate refusal of Gustav to allow his destined bride liberty of worship according to the rites of the
Russian Orthodox Church — a rebuff which undoubtedly accelerated the death of the Russian empress. Nobody seems to have suspected the possibility at the time that emotional problems might lie at the root of Gustav's abnormal piety.
On the contrary, when he came of age that year, thereby ending the regency, there were many who prematurely congratulated themselves on the fact that Sweden had now no disturbing genius, but an economical, God-fearing, commonplace monarch to deal with.
Politics
Gustav Adolf's prompt dismissal of the generally detested
Gustaf Adolf Reuterholm, the duke-regent's leading advisor, added still further to his popularity. On
October 31,
1797 Gustav married
Friederika, granddaughter of
Karl Friedrich, Margrave of
Baden, a marriage which seemed to threaten war with
Russia but for the fanatical hatred of the
French republic shared by the
Emperor Paul of Russia and Gustav IV Adolf, which served as a bond of union between them. Indeed the king's horror of
Jacobinism was morbid in its intensity, and drove him to become increasingly reactionary and to postpone his coronation for some years, so as to avoid calling together a diet. Nonetheless, the disorder of the state finances, largely inherited from Gustav III's Russian war of 1788-92, as well as widespread crop failures in 1798 and 1799, compelled him to summon the
estates to
Norrköping in March
1800 and on
April 3 the same year. When the king encountered serious opposition at the riksdag, he resolved never to call another.
Loss of Finland
His reign was ill-fated and was to end abruptly. In 1805, he joined the Third Coalition against Napoleon. His campaign went poorly and the French occupied Swedish Pomerania. When his ally, Russia, made peace and concluded an alliance with France at Tilsit in 1807, Sweden and Portugal were left as Great Britain's European allies. In the winter of 1808, Russia invaded Swedish-occupied Finland on the pretext of compelling Sweden to join Napoleon's Continental System. Denmark likewise declared war on Sweden. By early 1809, less than one year, Sweden surrendered all of Finland to Russia, which Emperor Alexander I then established as an autonomous grand-duchy under his suzerainty.
Coup d'etat and abdication

Gustav arrested.
Gustav Adolf's inept and erratic leadership in diplomacy and war precipitated his deposition through a conspiracy of army officers. On
March 13,
1809 seven of the conspirators broke into the royal apartments in the palace, seized the king, and imprisoned him and his family in
Gripsholm castle; Duke Charles (Karl) was thereupon persuaded to accept the leadership of a provisional government, which was proclaimed the same day; and a diet, hastily summoned, solemnly approved of the revolution.
On
March 29 Gustav IV Adolf, to save the crown for his son, voluntarily abdicated; but on
May 19 the
Riksdag of the Estates, dominated by the
army, declared that not merely Gustav but his whole family had forfeited the throne. On
June 5 the duke regent (Gustav's uncle) was proclaimed king under the title of
Charles XIII, after accepting a new liberal
constitution, which was ratified by the diet the same day. In December Gustav and his family were transported to
Germany.
In exile Gustav used several titles, Count
Gottorp, Duke of
Holstein-Eutin, and finally settled at
St. Gallen in
Switzerland where he lived in a small hotel in great loneliness and indigence, under the name of Colonel Gustafsson. It was there that he suffered a stroke and died. At the suggestion of King
Oscar II of Sweden his body was finally brought to Sweden and interred in the
Riddarholmskyrkan.
Ancestors
Family

Gustav Adolf and Frederica Dorothea.
In
1797 he had married
Frederika Dorothea Wilhelmina of Baden (
1781–
1826), with whom he had five children:
# Crown Prince
Gustav, after
1809 known as ''Gustaf Gustafsson, Prince of Vasa'' (
November 9,
1799–
1877)
# Princess
Sofia Wilhelmina (
May 21,
1801–
1865), married Grand Duke
Leopold I of Baden
# Prince Carl Gustaf,
Grand Duke of Finland (
December 2,
1802–
1805)
# Princess Amalia Maria Charlotta (
February 22,
1805–
1853), unmarried.
# Princess
Cecilia (
June 22,
1807–
1844), married August,
Grand Duke of Oldenburg.
His son Gustav would serve as an officer in the service of the
Habsburgs of
Austria, but would never father a son of his own, only a daughter, later Queen Consort
Carola of Saxony, wife of Saxony's King
Albert I. Sofia Wilhelmina would marry Grand Duke
Leopold of Baden, and their grand-daughter
Victoria of Baden would marry into the House of
Bernadotte, i.e
Gustav V of Sweden. By
1812, Gustav Adolf divorced his consort and following this he had several mistresses, among them
Maria Schlegel who gave him the son
Adolf Gustafsson.
