Anne of Denmark (Danish: Anna; 12 December 1574 – 2 March 1619) was Queen of Scotland from her marriage to King James VI on 20 August 1589, and Queen of England and Ireland from the union of the Scottish and English Crowns on 24 March 1603, until her death in 1619. The second daughter of King Frederick II of Denmark and Sophie of Mecklenburg-Güstrow, Anne married James at age 14. They had three children who survived infancy: Henry Frederick, Prince of Wales, who predeceased his parents; Princess Elizabeth, who became Queen of Bohemia; and James's future successor, Charles I. Anne demonstrated an independent streak and a willingness to use factional Scottish politics in her conflicts with James over the custody of Prince Henry and his treatment of her friend Beatrix Ruthven. Anne appears to have loved James at first, but the couple gradually drifted and eventually lived apart, though mutual respect and a degree of affection survived. In England, Anne shifted her energies from factional politics to patronage of the arts and constructed her own magnificent court, hosting one of the richest cultural salons in Europe. After 1612, she had sustained bouts of ill health and gradually withdrew from the centre of court life. Though she was reported to have been a Protestant at the time of her death, she may have converted to Catholicism at some point. Some historians have dismissed Anne as frivolous and self-indulgent. However, 18th-century writers including Thomas Birch and William Guthrie considered her a woman of "boundless intrigue". Recent reappraisals acknowledge Anne's assertive independence and, in particular, her dynamic significance as a patron of the arts during the Jacobean age.
