Margaret Stuart (or Stewart) (c. 1591 – 4 August 1639), was an English court office holder.
 She served as lady-in-waiting to the queen consort of England, Anne of Denmark.
 She was the daughter of James Stewart, 2nd Earl of Moray, and Elizabeth Stuart, 2nd Countess of Moray.
Saint Margaret of Scotland (c. 1045 – 16 November 1093), also known as Margaret of Wessex, was an English princess of the House of Wessex.
 Margaret was sometimes called "The Pearl of Scotland".
 Born in exile in the Kingdom of Hungary, she was the sister of Edgar Ætheling, the shortly reigned and uncrowned Anglo-Saxon King of England.
 Margaret and her family returned to the Kingdom of England in 1057, but fled to the Kingdom of Scotland following the Norman conquest of England in 1066.
 In 1070 Margaret married King Malcolm III of Scotland, becoming Queen of Scots.
 She was a very pious Roman Catholic, 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 a 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, she died at Edinburgh Castle in Edinburgh, Scotland in 1093, merely days after receiving the news of her husband's death in battle.
 In 1250 Pope Innocent IV canonized her, and her remains were reinterred in a shrine in Dunfermline Abbey in Fife, Scotland.
 Her relics were dispersed after the Scottish Reformation and subsequently lost.
 Mary, Queen of Scots at one time owned her head, which was subsequently preserved by Jesuits in the Scottish College, Douai, France, from where it was subsequently lost during the French Revolution.
The Treaty of Tours was an agreement between Henry VI of England and the Charles VII of France, signed on 22 May 1444.
 The terms stipulated the marriage of Charles VII's fifteen-year-old niece, Margaret of Anjou, to Henry VI and the agreement of a 21-month truce between the Kingdoms of England and France.
 In exchange for the marriage, Charles wanted the area of Maine in northern France.
 Henry VI married Margaret a year later, in April 1445, when Henry VI was 23 years old.
 He did not, however, give up Maine.
 Charles threatened Henry VI and sent envoys to pressure him; even Margaret tried to persuade Henry to give it up.
 Henry eventually yielded in 1448 when Charles VII threatened English garrisons with a large army.
 The Treaty was seen as a major failure for England as the bride secured for Henry VI was a poor match, being related to King Charles VII only distantly, and through marriage rather than by blood.
 Her marriage came also without a dowry, when the amount that should have been given was 20,000 livres.
 Margaret of Anjou was the daughter of the impoverished René of Anjou and in addition to being presented with Margaret without a dowry, Henry was also expected to pay for the wedding.
 The Treaty of Tours exacerbated rifts between the court's Beaufort faction and the Dukes of Gloucester and York, and has been considered a potentially contributory factor to the outbreak of the Wars of the Roses.
Margaret Dymoke (born "circa" 1500) was a lady-in-waiting at the court of Henry VIII of England.
 Her married names were Vernon, Coffin and Manners.
 She was born around 1500 in Scrivelsby, Lincolnshire, the daughter of Sir Robert Dymoke of Scrivelsby and Anne Sparrow.

In the autumn of 1016, the Danish prince Cnut the Great (aka Canute) successfully invaded England.

The Plantagenets is a 2014 television documentary series on the House of Plantagenet, which ruled England from 1154 to 1485.
 The series aired from 17 March to 31 March 2014 on BBC Two and was presented by historian Robert Bartlett.
The Royal Arms of England are the armorials (or coat of arms) first adopted in a fixed form at the start of the age of heraldry (circa 1200) as personal arms by the Plantagenet kings who ruled England from 1154.
 In the popular mind they have come to symbolise the nation of England, although according to heraldic usage nations do not bear arms, only persons and corporations do.
 The blazon of the Arms of Plantagenet is: "Gules, three lions passant guardant in pale or armed and langued azure", signifying three identical gold lions (also known as leopards) with blue tongues and claws, walking past but facing the observer, arranged in a column on a red background.
 Although the tincture "azure" of tongue and claws is not cited in many blazons, they are historically a distinguishing feature of the Arms of England.
 This coat, designed in the High Middle Ages, has been variously combined with those of the Kings of France, Scotland, a symbol of Ireland, the House of Nassau and the Kingdom of Hanover, according to dynastic and other political changes occurring in England, but has not altered since it took a fixed form in the reign of Richard I (1189–1199), the second Plantagenet king.
Henry VIII (28 June 1491 – 28 January 1547) was King of England from 21 April 1509 until his death.

An Armstrong Gun was a uniquely designed type of rifled breech-loading field and heavy gun designed by Sir William Armstrong and manufactured in England beginning in 1855 by the Elswick Ordnance Company and the Royal Arsenal at Woolwich.
 Such guns involved a built-up gun construction system of a wrought-iron (later of mild steel) tube surrounded by multiple wrought-iron strengthening coils shrunk over the inner tube to keep it under compression.
