Charles II (29 May 1630 – 6 February 1685) was king of England, Scotland and Ireland.
 He was king of Scotland from 1649 until his deposition in 1651, and king of England, Scotland and Ireland from the restoration of the monarchy in 1660 until his death.
Isabel Stuart (28 August 1676 – 2 March 1681) was a daughter of the future King James II of England and his second wife, Mary of Modena.
Secret Love, or The Maiden Queen is a 1667 tragicomedy written by John Dryden.
 The play, commonly known by its more distinctive subtitle, was acted by the King's Company at the Theatre Royal, Drury Lane (which had escaped the Great Fire of London the year before).
 The premiere occurred on 2 March, and was a popular success.
 King Charles II, his brother the Duke of York and future King James II, and Samuel Pepys were all in the audience on opening night.
The Patriot Parliament is the name given to the session of the Irish Parliament called by King James II of Ireland during the War of the Two Kings in 1689.
 The parliament met in one session, from 7 May 1689 to 20 July 1689, and was the only session of the Irish Parliament under King James II.
The Monmouth Rebellion, also known as The Revolt of the West or The West Country rebellion, was an attempt to overthrow James II, the Duke of York who had become King of England, Scotland, and Ireland upon the death of his elder brother Charles II on 6 February 1685.
 James II was a Roman Catholic, and some Protestants under his rule opposed his kingship.
 James Scott, 1st Duke of Monmouth, an illegitimate son of Charles II, claimed to be rightful heir to the throne and attempted to displace James II.
Robert Stewart, Duke of Albany (c. 1340 – 3 September 1420), a member of the Scottish royal house, served as regent (at least partially) to three different Scottish monarchs (Robert II, Robert III, and James I).
 He also held the titles of Earl of Menteith (28 February 1361), Earl of Fife (1361; resigned in 1372), Earl of Buchan (1394; resigned in 1406) and Earl of Atholl (1403, for the duration of Robert III's life only), in addition to his 1398 creation as Duke of Albany.
 A ruthless politician, Albany was widely regarded as having caused the murder of his nephew, the Duke of Rothesay, and brother to the future King James I of Scotland.
 James was held in captivity in England for eighteen years, during which time Albany served as regent in Scotland, king in all but name.
 He died in 1420 and was succeeded by his son, Murdoch Stewart, Duke of Albany, who would be executed for treason when James returned to Scotland in 1425, almost causing the complete ruin of the Albany Stewarts.
After the deposition by the English parliament in February 1689 of King James II and VII from the thrones of England and Ireland (the Scottish Estates followed suit on 11 April 1689), he and his successors continued to create peers and baronets, which they believed was their right.
 These creations were not recognised by James's "de facto" successors or British law, but the titles were used in Jacobite circles in Continental Europe and recognised by France, Spain and the Papacy.
 The following tables list the peerages and baronetcies created by the Stuart claimants in exile.
 The tables present the situation from the Jacobite perspective, and so titles granted after 1689 by King James II & VII's "de facto" successors to the throne, whose authority was not recognised by Jacobites, are represented in inverted commas.
Anne Hyde (12 March 163731 March 1671) was Duchess of York and of Albany as the first wife of the future King James II of England.
 Originally an Anglican, she converted to Catholicism soon after her marriage to James.
 This took place in 1660 after she became pregnant by him, but he is said to have promised to marry her the year before.
 The two first met in the Netherlands while Anne was living in the household of James' sister Mary.
 James and Anne had eight children, but six died in early childhood.
 The two who survived to adulthood were Mary, who succeeded her father after his deposition during the Glorious Revolution of 1688, and Anne, who succeeded her brother-in-law and became the first monarch of Great Britain.
James FitzJames, 1st Duke of Berwick, 1st Duke of Fitz-James, 1st Duke of Liria and Jérica (21 August 1670 – 12 June 1734) was an Anglo-French military leader, illegitimate son of King James II of England by Arabella Churchill, sister of the 1st Duke of Marlborough.
 Berwick was a successful general in the pay of Louis XIV of France.
Murdoch Stewart, Duke of Albany (Scottish Gaelic: "Muireadhach Stiubhart" ) (1362 – 24 May 1425) was a leading Scottish nobleman, the son of Robert Stewart, Duke of Albany and the grandson of King Robert II of Scotland, who founded the Stewart dynasty.
 In 1389, he became Justiciar North of the Forth.
 In 1402, he was captured at the Battle of Homildon Hill and would spend 12 years in captivity in England.
 After his father died in 1420, and while the future King James I of Scotland was himself held captive in England, Stewart served as Governor of Scotland until 1424, when James was finally ransomed and returned to Scotland.
 However, in 1425, soon after James's coronation, Stewart was arrested, found guilty of treason, and executed, along with two of his sons.
 His only surviving heir was James the Fat, who escaped to Antrim, Ireland, where he died in 1429.
 Stewart's wife Isabella of Lennox survived the destruction of her family, and she would live to see the murder of James I and the restoration of her title and estates.
