List of Scottish royal consorts in the context of "Mary of Guise"

Catherine of Braganza (Portuguese: Catarina de Bragança; 25 November 1638 – 31 December 1705) was Queen of England, Scotland and Ireland during her marriage to King Charles II, which lasted from 21 May 1662 until his death on 6 February 1685. She was the daughter of John IV of Portugal, who became the first king from the House of Braganza in 1640, after overthrowing the 60-year rule of the Spanish Habsburgs over Portugal. Catherine served as the regent of Portugal during the absence of her brother Peter II in 1701, and again in 1704–1705, after her return to her homeland as a widow.

Owing to her devotion to the Roman Catholic faith in which she had been raised, just like her mother-in-law, Catherine was unpopular in England. She was a special object of attack by the inventors of the Popish Plot. In 1678 the murder of Edmund Berry Godfrey was ascribed to her servants, and Titus Oates accused her of an intention to poison the king. These charges, the absurdity of which was soon shown by cross-examination, nevertheless placed Catherine for some time in great danger. On 28 November 1678, Oates accused Catherine of high treason, and the English House of Commons passed an order for the removal of her and of all Roman Catholics from the Palace of Whitehall. Several further depositions were made against her, and in June 1679 it was decided that she should stand trial, which threat however was lifted by the king's intervention, for which she later showed him much gratitude.

Henrietta Maria of France (French: Henriette Marie; 25 November 1609 – 10 September 1669) was Queen of England, Scotland and Ireland from her marriage to King Charles I on 13 June 1625 until his execution on 30 January 1649. She was the mother of Charles II and James II and VII. Under a decree of her husband, she was known in England as Queen Mary, but she did not like this name and signed her letters "Henriette" or "Henriette Marie".

Henrietta Maria's Roman Catholicism made her unpopular in England, and also prohibited her from being crowned in a Church of England service; therefore, she never had a coronation. She immersed herself in national affairs as civil war loomed, and in 1644, following the birth of her youngest daughter, Henrietta, during the height of the First English Civil War, was compelled to seek refuge in France. The execution of Charles I in 1649 left her impoverished. She settled in Paris and returned to England after the Restoration of Charles II to the throne. In 1665, she moved back to Paris, where she died four years later.

Gruoch ingen Boite (fl. c. 1015 – unknown) was a Scottish queen, the daughter of Boite mac Cináeda, son of Cináed II. The dates of her life are uncertain. She is most famous for being the wife and queen of MacBethad mac Findlaích (Macbeth), as well as the basis for Lady Macbeth in Shakespeare's Macbeth. However, Shakespeare's Macbeth is based on Holinshed's Chronicles (published in 1577) and is not historically accurate.

Margaret Tudor (29 November 1489 – 18 October 1541) was Queen of Scotland from 1503 until 1513 by marriage to James IV. She then served as regent of Scotland during her son's minority, and fought to extend her regency. Margaret was the eldest daughter and second child of Henry VII of England and Elizabeth of York, and the elder sister of Henry VIII. By her line, the House of Stuart eventually acceded to the throne of England and Ireland, in addition to Scotland.

Margaret married James IV at the age of 13, in accordance with the Treaty of Perpetual Peace between England and Scotland. Together, they had six children, though only one of them reached adulthood. Margaret's marriage to James linked the royal houses of England and Scotland, which a century later resulted in the Union of the Crowns. Following the death of James IV at the Battle of Flodden in 1513, Margaret, as queen dowager, was appointed as regent for their son James V. A pro-French party took shape among the nobility, urging that the king's closest male relative, John Stewart, Duke of Albany, should replace Margaret as regent. In seeking allies, Margaret turned to the Douglases, and in 1514 she married Archibald Douglas, 6th Earl of Angus, with whom she had one daughter, Margaret Douglas. Margaret's marriage to Angus alienated other powerful nobles and saw Albany take her place as regent. In 1524, Margaret, with the help of the Hamiltons, removed Albany from power in a coup d'état while he was in France, and was recognised by Parliament as regent, then later as chief counsellor to James V when he came of age.

Anne of Denmark (Danish: Anna; 12 December 1574 – 2 March 1619) was Queen of Scotland from her marriage to James VI and I 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.

Saint Margaret of Scotland (Scottish Gaelic: Naomh Maighréad; Scots: Saunt Marget, c. 1045 – 16 November 1093), also known as Margaret of Wessex, was Queen of Alba from 1070 to 1093 as the wife of King Malcolm III. Margaret was sometimes called "The Pearl of Scotland". She was a member of the House of Wessex and was born in the Kingdom of Hungary to the expatriate English prince Edward the Exile. She and her family returned to England in 1057. Following the death of Harold Godwinson at the Battle of Hastings in 1066, her brother Edgar Ætheling was elected King of England but never crowned. After the family fled north, Margaret married Malcolm III of Scotland by the end of 1070.

Margaret was a pious Christian, and among many charitable works she established a ferry across the Firth of Forth in Scotland for pilgrims travelling to St Andrews in Fife, which gave the towns of South Queensferry and North Queensferry their names. Margaret was the mother of three kings of Scotland, or four, if Edmund of Scotland (who ruled with his uncle, Donald III) is counted, and of Matilda of Scotland, queen consort of England. According to the Vita S. Margaritae (Scotorum) Reginae (Life of St Margaret, Queen (of the Scots)), attributed to Turgot of Durham, Margaret died at Edinburgh Castle in 1093, days after receiving the news of her husband and son's deaths in battle.

Henry Stuart, Lord Darnley (1546 – 10 February 1567) was King of Scotland as the second husband of Mary, Queen of Scots, from 29 July 1565 until his murder. Darnley had one child with Mary, James VI of Scotland and I of England. Less than a year after the birth of his son, Darnley was murdered at Kirk o' Field in 1567. Many contemporary narratives describing his life and death refer to him as simply Lord Darnley, his title as heir apparent to the Earldom of Lennox.

Mary of Modena (Italian: Maria Beatrice Eleonora Anna Margherita Isabella d'Este; 5 October [O.S. 25 September] 1658 – 7 May [O.S. 26 April] 1718) was Queen of England, Scotland and Ireland as the second wife of James VII and II. A devout Roman Catholic, Mary married the widower James, who was then the younger brother and heir presumptive of Charles II. She was devoted to James and their children, two of whom survived to adulthood: the Jacobite claimant to the thrones, James Francis Edward, and Louisa Maria Teresa.

Born a princess of the northwestern Italian Duchy of Modena, Mary is primarily remembered for the controversial birth of Prince James Francis Edward, her only surviving son. It was widely rumoured that he was smuggled into the birth chamber in a warming pan in order to perpetuate her husband's Roman Catholic Stuart dynasty. James Francis Edward's birth was a contributing factor to the "Glorious Revolution", the revolution which deposed James II and VII, and replaced him with Mary II, a Protestant, the elder of James II's daughters from his first marriage to Anne Hyde (1637–1671). Mary II and her husband, William III of Orange, would reign jointly over all three kingdoms.
