Elizabeth Woodville in the context of "Elizabeth of York"

Richard Neville, 16th Earl of Warwick, 6th Earl of Salisbury, KG (22 November 1428 – 14 April 1471), known as Warwick the Kingmaker, was an English nobleman, administrator, landowner of the House of Neville fortune and military commander. The eldest son of Richard Neville, 5th Earl of Salisbury, he became Earl of Warwick through marriage, and was the wealthiest and most powerful English peer of his age, with political connections that went beyond the country's borders. One of the leaders in the Wars of the Roses, originally on the Yorkist side but later switching to the Lancastrian side, he was instrumental in the deposition of two kings, which led to his epithet of "Kingmaker".

Through fortunes of marriage and inheritance, Warwick emerged in the 1450s at the centre of English politics. Originally, he was a supporter of King Henry VI; however, a territorial dispute with Edmund Beaufort, Duke of Somerset, led him to collaborate with Richard, Duke of York, in opposing the king. From this conflict, he gained the strategically valuable post of Captain of Calais, a position that benefited him greatly in the years to come. The political conflict later turned into a full-scale rebellion, where in battle York was slain, as was Warwick's father Salisbury. York's son, however, later triumphed with Warwick's assistance and was crowned King Edward IV. Edward initially ruled with Warwick's support, but the two later fell out over foreign policy and the king's choice to marry Elizabeth Woodville. After a failed plot to crown Edward's brother, George, Duke of Clarence, Warwick instead restored Henry VI to the throne. The triumph was short-lived, however: on 14 April 1471, Warwick was defeated by Edward at the Battle of Barnet, and killed.

George of York, Duke of Bedford (March 1477 – March 1479) was the eighth child and third son of Edward IV of England and Elizabeth Woodville.

George was born in Windsor Castle in March 1477, and was created Duke of Bedford in infancy, probably in 1478, after the former holder of the title, George Neville, was deprived of the title by act of Parliament, ostensibly for lack of money to maintain the style of a duke. He was appointed the Lord Lieutenant of Ireland in 1478, one of a series of nominal and largely absent lieutenants.

Edward IV (28 April 1442 – 9 April 1483) was King of England from 4 March 1461 to 3 October 1470, then again from 11 April 1471 until his death in 1483. He was a central figure in the Wars of the Roses, a series of civil wars in England fought between the Yorkist and Lancastrian factions between 1455 and 1487.

Edward inherited the Yorkist claim to the throne at the age of eighteen when his father, Richard, Duke of York, was killed at the Battle of Wakefield in December 1460. After defeating Lancastrian armies at Mortimer's Cross and Towton in early 1461, he deposed King Henry VI and took the throne. His marriage to Elizabeth Woodville in 1464 led to conflict with his chief advisor, Richard Neville, Earl of Warwick, known as the "Kingmaker". In 1470, a revolt led by Warwick and Edward's brother George, Duke of Clarence, briefly re-installed Henry VI. Edward fled to Flanders, where he gathered support and invaded England in March 1471; after victories at the battles of Barnet and Tewkesbury (where both the Earl of Warwick and Edward of Westminster, Prince of Wales, were killed), he resumed the throne. Shortly afterwards, Henry VI was found dead in the Tower of London, possibly killed on Edward's orders.

The Princes in the Tower refers to the mystery of the fate of the deposed King Edward V of England and his younger brother Prince Richard of Shrewsbury, Duke of York, heirs to the throne of King Edward IV of England. The brothers were the only sons of the king by his queen, Elizabeth Woodville, living at the time of their father's death in 1483. Aged 12 and 9 years old, respectively, they were lodged in the Tower of London by their paternal uncle and England's regent, Richard, Duke of Gloucester, in preparation for Edward V's forthcoming coronation. Before the young king's coronation, however, he and his brother were declared illegitimate by Parliament. Gloucester ascended the throne as Richard III.

It is unclear what happened to the two princes after the last recorded sighting of them in the tower. It is generally assumed that they were murdered; a common hypothesis is that the murder was commissioned by Richard III in an attempt to secure his hold on the throne. Their deaths may have occurred sometime in 1483, but apart from their disappearance, the only evidence is circumstantial. As a result, several other theories about their fates have been proposed, including the suggestion that they were murdered by their kinsman the Duke of Buckingham, their future brother-in-law King Henry VII, or his mother Lady Margaret Beaufort, among others. It has also been suggested that one or both princes may have escaped assassination. In 1487, Lambert Simnel initially was crowned in Dublin as "King Edward", but later claimed by others to be York's cousin the Earl of Warwick. And again several years later, from 1491 until his capture in 1497, Perkin Warbeck claimed to be the Duke of York, having supposedly escaped to Flanders. Warbeck's claim was supported by some contemporaries, including York's aunt the Duchess of Burgundy.

Richard of Shrewsbury, Duke of York (17 August 1473 – disappeared July 1483) was the second son of King Edward IV of England and Elizabeth Woodville. Richard and his older brother, who briefly reigned as King Edward V of England, mysteriously disappeared shortly after their uncle Richard III became king in 1483.

Cecily of York (20 March 1469 – 24 August 1507), also known as Cecelia, was the third daughter of King Edward IV of England and his queen consort Elizabeth Woodville.

Shortly after the death of her father and before the assumption of the throne by her uncle King Richard III, Cecily and her siblings were declared illegitimate. Queen Elizabeth, fearing for the children's lives, moved them to Westminster Abbey, where the late king's family received asylum and spent about a year. After Richard III promised not to harm the children, Cecily and her sisters went to court. Soon there may have been rumors that the king was going to marry one of his nieces – Elizabeth or Cecily. However, shortly before his death, Richard III arranged the marriage of Cecily to one of his supporters – Ralph Scrope, the younger brother of the 6th Baron Scrope of Masham, who was much lower in status by birth than the princess.
