Monarchy of Ireland in the context of "Tudor conquest of Ireland"

James II and VII (14 October 1633 O.S. – 16 September 1701) was King of England and Ireland as James II and King of Scotland as James VII from February 1685 until he was deposed in the 1688 Glorious Revolution. The last Catholic monarch of England, Scotland, and Ireland, his reign is remembered primarily for conflicts over religion. However, it also involved struggles over the principles of absolutism and divine right of kings, with his deposition ending a century of political and civil strife by confirming the primacy of the English Parliament over the Crown.

James was the second surviving son of Charles I of England and Henrietta Maria of France, and was created Duke of York at birth. At the age of 51, he succeeded to the throne with widespread support on the death of his elder brother, Charles II. The general public were reluctant to undermine the principle of hereditary succession after the trauma of the brief republican Commonwealth of England 25 years before, and believed that a Catholic monarchy was purely temporary. However, tolerance of James's personal views did not extend to Catholicism in general, and both the English and Scottish parliaments refused to pass measures viewed as undermining the primacy of the Protestant religion. His attempts to impose them by absolutist decrees as a matter of his perceived divine right met with opposition.

Lady Jane Grey (1536/1537 – 12 February 1554), also known as Lady Jane Dudley after her marriage, and nicknamed as the "Nine Days Queen", was an English noblewoman who was proclaimed Queen of England and Ireland on 10 July 1553 and reigned until she was deposed by the Privy Council of England, which proclaimed her cousin, Mary I, as the new Queen on 19 July. Jane was later beheaded for high treason.

Jane was the great-granddaughter of Henry VII (through his youngest daughter, Mary Tudor), the grandniece of Henry VIII, and the first cousin once removed of Edward VI, Mary I, and Elizabeth I. Under the will of Henry VIII, Jane was in line to the throne after her cousins. She had a humanist education and a reputation as one of the most learned young women of her day. In May 1553, she was married to Lord Guildford Dudley, a younger son of Edward VI's chief minister, John Dudley, Duke of Northumberland. In June, the dying Edward VI wrote his will, nominating Jane and her male heirs as successors to the Crown, in part because his half-sister Mary was Catholic, whereas Jane was a committed Protestant and would support the reformed Church of England, whose foundation Edward laid. The will removed both of his half-sisters, Mary and Elizabeth, from the line of succession because of their illegitimacy, subverting their lawful claims under the Third Succession Act. Through the Duke of Northumberland, Edward's letters patent in favour of Jane were signed by the entire privy council, bishops, and other notables.

Henry Frederick, Prince of Wales KG (19 February 1594 – 6 November 1612) was the eldest son and heir apparent of King James VI and I and Anne of Denmark. His name derives from his grandfathers: Henry Stuart, Lord Darnley; and Frederick II of Denmark. Prince Henry was widely seen as a bright and promising heir to the English, Irish, and Scottish thrones. However, at the age of 18, he predeceased his father, dying of typhoid fever. His younger brother, the future Charles I, succeeded him as heir apparent to the thrones.

Henry IV (c. April 1367 – 20 March 1413), also known as Henry Bolingbroke, was King of England from 1399 to 1413, Lord of Ireland and duke of Aquitaine. Henry was the son of John of Gaunt, Duke of Lancaster and a grandson of King Edward III.

When Henry came of age, he was involved in the 1388 revolt of the Lords Appellant against his first cousin, King Richard II. Henry was later exiled from England in 1397. After Henry's father died in 1399, Richard blocked Henry's inheritance to the holdings of the House of Lancaster. So, Henry rallied Lancastrian supporters, imprisoned Richard II and formally deposed him, usurping the throne. These actions later contributed to dynastic disputes in the Wars of the Roses (1455–1487).

Mary II (30 April 1662 – 28 December 1694) was Queen of England, Scotland, and Ireland with her husband, King William III and II, from 1689 until her death in 1694. She was also Princess of Orange following her marriage on 4 November 1677. Her joint reign with William over Britain is known as that of William and Mary.

Mary was born during the reign of her uncle King Charles II. She was the eldest daughter of James, Duke of York (the future James II of England), and his first wife, Anne Hyde. Mary and her sister Anne were raised as Anglicans at the behest of Charles II, although their parents both converted to Roman Catholicism. Charles lacked legitimate children, making Mary second in the line of succession. At the age of 15, she married her cousin William of Orange, a Protestant. Charles died in 1685 and James became king, making Mary heir presumptive. James's attempts at rule by decree and the birth of his son from a second marriage, James Francis Edward (later known as "the Old Pretender"), led to his deposition in the Glorious Revolution of 1688 and the adoption of the English Bill of Rights.

William III and II (William Henry; Dutch: Willem Hendrik; 4 November 1650 – 8 March 1702), also known as William of Orange, was the sovereign Prince of Orange from birth, Stadtholder of Holland, Zeeland, Utrecht, Guelders, and Overijssel in the Dutch Republic from 1672, and King of England, Ireland, and Scotland from 1689 until his death in 1702. He ruled England, Scotland, and Ireland with his wife, Queen Mary II, and their joint reign is known as that of William and Mary.

William was the only child of William II, Prince of Orange, and Mary, Princess Royal, the daughter of King Charles I of England, Scotland, and Ireland. His father died before his birth, making William III the prince of Orange from birth. In 1677, he married his first cousin Mary, the elder daughter of his maternal uncle James, Duke of York (later King James II).
