Frederik III, King of Denmark and Norway was born on March 18, 1609, at Haderslevhus Castle in Haderslev, Denmark. He was the third but the second surviving of the four sons and the fifth but the fourth surviving of the six children of Christian IV, King of Denmark and Norway and his first wife Anna Katharina of Brandenburg. Frederik had an elder brother who had been elected heir apparent in 1608 (Denmark was an elected monarchy at that time) and was expected to succeed their father.

Frederik has five siblings:

Frederik III was raised by Beate Huitfeldt, the royal governess of the household of the royal princes, previously maid of honor to Frederik’s grandmother Sophie of Mecklenburg-Güstrow and principal lady-in-waiting to queen Anna Katharina of Brandenburg, Frederik’s mother. He was then educated from 1624 – 1626 at Sorø Academy in Sorø, Denmark, founded by his father, and then studied in France and the Netherlands from 1629 – 1630.

Frederik III’s mother Anna Katharina died on April 8, 1612, when Frederik was only three-years-old. His father King Christian IV had several mistresses and several illegitimate children who were Frederik’s half-siblings.

With Kirsten Madsdatter, the chambermaid of Christian IV’s first wife Anna Katharina:

With Karen Andersdatter, mistress from 1613-1616:

  • Dorothea Elisabeth Gyldenløve (1613–1615), died in childhood
  • Hans Ulrik Gyldenløve (link in Danish) (1615–1645), married Regitze Grubbe, no children

With Vibeke Kruse, the chambermaid of Christian IV’s second wife Kirsten Munk and Chrisitan IV’s official mistress from 1629 until his death in 1648:

In 1615, when Frederik was six-years-old, his father Christian IV married 18-year-old Kirsten Munk, from a wealthy, untitled noble Danish family. Their marriage would be morganatic, but legal, Kirsten would receive properties in her name and would be assured of a widow’s pension. Kirsten was not the Queen due to the morganatic marriage and was given the title Countess of Schleswig-Holstein. Christian IV and Kirsten’s ten children married into the Danish nobility, were styled Count and Countess of Schleswig-Holstein, and did not have succession rights.

Frederik III had ten half-siblings from his father’s second marriage to Kirsten Munk:

Because Frederik III had an elder brother who was the heir to the throne, his father King Christian IV sought to provide him with a pathway to his future and also to use Frederik to gain influence in the northern German areas of the Holy Roman Empire. Despite being christened a Protestant, Frederik became the administrator of the Prince-Archbishopric of Bremen and the Prince-Bishopric of Verden. In 1647, Friedrich was appointed governor of the Duchies of Schleswig and Holstein. He gained considerable experience as an administrator through these positions.

Before his marriage, Frederik III had one illegitimate son with his mistress Margrethe Pape, who later married county administrator and state councilor Daniel Hausmann and had three children. In 1683, Frederik III’s son Christian V granted Margrethe Pape the title Baroness of Løvendal. Frederik and Margrethe’s son Ulrik Frederik Gyldenløve was Governor-General of Norway (1664 – 1699) and was the commanding general in Norway during the Scanian War (1675 – 1679). The surname Gyldenløve (Golden Love) was used by illegitimate children of Danish kings.

  • Ulrik Frederik Gyldenløve, Count of Laurvig (1638 – 1704), married (1) Sophie Urne, had two sons, divorced (2) Marie Grubbe, no children, divorced (3) Countess Antoinette Augusta von Aldenburg, had three daughters and one son

In the 1630s, there had been unsuccessful negotiations for a marriage between Frederik III and Queen Christina of Sweden. Finally, in March 1640, 31-year-old Frederik was betrothed 12-year-old Sophie Amalie of Brunswick-Lüneburg, daughter of Georg, Duke of Brunswick-Lüneburg and Anna Eleonore of Hesse-Darmstadt. Because of the young age of the bride, the marriage was delayed. On October 1, 1643, at Glücksborg Castle in Glücksborg, Duchy of Schleswig, now in the German state of Schleswig-Holstein, Frederik III and Sophie Amalie of Brunswick-Lüneburg were married.

Frederik III and Sophie Amalie of Brunswick-Lüneburg had eight children:

Frederik III and Sophie Amalie lived in the Prince-Archbishopric of Bremen and the Duchies of Schleswig and Holstein until a sudden event changed their lives. On June 2, 1647, Frederik’s 44-year-old childless elder brother Christian, Prince-Elect of Denmark and heir apparent to the Norwegian throne, died and his death opened up the possibility for Frederik to be elected heir apparent to the Danish throne. However, when King Christian IV died less than nine months later, on February 28, 1648, Frederik had not yet been elected heir apparent to the Danish throne. After long deliberations between the Danish Estates and the Rigsraadet (royal council), he was finally elected King of Denmark. King Frederik III and Queen Sophie Amalie were crowned on November 23, 1648.

Five of Frederik III’s half-sisters, the daughters of Christian IV and Kirsten Munk, had married powerful Danish noblemen, collectively called the Party of the Sons-in-Law, and played important roles in the Danish government from 1648 – 1651. Frederik had a particular problem with his brother-in-law Count Corfitz Ulfeldt, husband of his half-sister Countess Leonora Christina of Schleswig-Holstein. There were rumors that Count Corfitz Ulfeldt was associated with a plot to poison Frederik III and Ulfeldt and his wife left Denmark and settled in Sweden. The plot was proven to be false but Ulfeldt agreed to accept the offer of King Karl X Gustav of Sweden to enter his service because he wanted to humiliate King Frederik III, his wife’s half-brother. Ulfeldt participated in the Swedish invasion of Denmark in the Danish-Swedish War of 1657 – 1658. Kirsten allegedly financially supported the invasion of Denmark by King Karl X Gustav of Sweden. Because of this, the Danish government withdrew the title of Count/Countess of Schleswig-Holstein from Kirsten Munk and her children. Frederik III’s brother-in-law Count Corfitz Ulfeldt is considered the most notorious traitor in Danish history. He was tried in absentia for high treason, his property was confiscated, and his children were banished. Ulfeldt, who was seriously ill, died in 1664 while on the run. Because of her alleged involvement in intrigues of her husband Count Corfitz Ulfeldt, Frederik III’s half-sister Leonora Christina was imprisoned for 22 years as a political prisoner. Only after the death of Frederik III’s wife Queen Sophie Amalie did Leonora Christina gain her freedom.

In 1660, Frederik III used his popularity to end the elective monarchy in favor of a hereditary, absolute monarchy in which the legislature was dissolved and the monarch ruled by decree. This lasted until 1849 when Denmark-Norway became a hereditary, constitutional monarchy. Frederik maintained a life-long interest in interest in theology, the natural sciences, and Scandinavian history. He was an enthusiastic collector of books and his collection became the foundation for the Royal Library in Copenhagen which he founded in 1648.

Frederik III, King of Denmark and Norway died at the age of 60, after three days of a painful illness, on February 9, 1670, at Copenhagen Castle in Copenhagen, Denmark. His wife Sophie Amalie of Brunswick-Lüneberg survived him by fifteen years, dying on February 20, 1685, aged 56. They were interred with Frederik’s parents in the crypt of Roskilde Cathedral, the traditional burial site of the Danish royal family in Roskilde, Denmark. In 1613, a year after the death of his first wife and Frederik’s mother Anna Katharina of Brandenburg, Christian IV ordered the construction of a new burial chapel because the space inside Roskilde Cathedral for burials was running out. However, the interior of the Christian IV Chapel was not completed until 1866. At that time, the caskets of Christian IV (died 1648), his first wife Anna Katharina of Brandenburg (died 1612), his eldest son and heir apparent Christian who predeceased him (died 1647), his second son who succeeded him as King Frederik III (died 1670); and Frederik III’s wife Sophie Amalie of Brunswick-Lüneberg (died 1685) were placed in the completed Christian IV Chapel.
