House of York in the context of "Battle of Barnet"

Duke of Bedford (named after Bedford, England) is a title that has been created six times (for five distinct people) in the Peerage of England. The first creation came in 1414 for Henry IV's third son, John, who later served as regent of France. In 1433 he surrendered the title and it was re-granted to him. The title became extinct on his death in 1435. The third creation came in 1470 in favour of George Neville, nephew of Warwick the Kingmaker. He was deprived of the title by Act of Parliament in 1478. The fourth creation came in 1478 in favour of George, the third son of Edward IV. He died the following year at the age of two. The fifth creation came in 1485 in favour of Jasper Tudor, half-brother of Henry VI and uncle of Henry VII. He had already been created Earl of Pembroke in 1452. However, as he was a Lancastrian, his title was forfeited between 1461 and 1485 during the predominance of the House of York. He regained the earldom in 1485 when his nephew Henry VII came to the throne and was elevated to the dukedom the same year. He had no legitimate children and the titles became extinct on his death in 1495.

John Russell, a close adviser of Henry VIII and Edward VI, was granted the title of Earl of Bedford in 1551, and his descendant William, 5th Earl, was created Duke in 1694, following the Glorious Revolution. The Russell family currently holds the titles of Earl and Duke of Bedford.

The Wars of the Roses, known at the time and in following centuries as the Civil Wars, and also the Cousins' War, were a series of armed confrontations, machinations, battles and campaigns fought for control of the English throne from 1455 to 1487. The conflict was fought between supporters of the House of Lancaster (emblem a red rose) and House of York (white rose), two rival cadet branches of the royal House of Plantagenet. The conflict resulted in the end of Lancaster's male line in 1471, leaving the Tudor family to inherit their claim to the throne through the female line. Conflict was largely brought to an end upon the union of the two houses through marriage, creating the Tudor dynasty that would subsequently rule England.

The Wars of the Roses were rooted in English socio-economic troubles caused by the Hundred Years' War (1337–1453) with France, as well as the quasi-military bastard feudalism resulting from the powerful duchies created by King Edward III. The mental instability of King Henry VI of the House of Lancaster revived his cousin Richard, Duke of York's interest in a claim to the throne. Warfare began in 1455 with York's capture of Henry at the First Battle of St Albans, upon which York was appointed Lord Protector by Parliament. Fighting resumed four years later when Yorkists led by Richard Neville, Earl of Warwick, captured Henry again at the Battle of Northampton. After attempting to seize the throne, York was killed at the Battle of Wakefield, and his son Edward inherited his claim per the controversial Act of Accord. The Yorkists lost custody of Henry in 1461 after the Second Battle of St Albans, but defeated the Lancastrians at the Battle of Towton. The Yorkist Edward was formally crowned in June 1461.

Richard III (2 October 1452 – 22 August 1485) was King of England from 26 June 1483 until his death in 1485. He was the last king of the Plantagenet dynasty and its cadet branch the House of York. His defeat and death at the Battle of Bosworth Field marked the end of the Middle Ages in England.

Richard was created Duke of Gloucester in 1461 after the accession to the throne of his older brother Edward IV. This was during the period known as the Wars of the Roses, an era when two branches of the royal family contested the throne; Edward and Richard were Yorkists, and their side of the family faced off against their Lancastrian cousins. In 1472, Richard married Anne Neville, daughter of Richard Neville, 16th Earl of Warwick, and widow of Edward of Lancaster, son of Henry VI, a Lancastrian. He governed northern England during Edward's reign, and played a role in the invasion of Scotland in 1482. When Edward IV died in April 1483, Richard was named Lord Protector of the realm for Edward's eldest son and successor, the 12-year-old Edward V. Before arrangements were complete for Edward V's coronation, scheduled for 22 June 1483, the marriage of his parents was declared bigamous and therefore invalid. Now officially illegitimate, Edward and his siblings were barred from inheriting the throne. On 25 June, an assembly of lords and commoners endorsed a declaration to this effect, and proclaimed Richard as the rightful king. He was crowned on 6 July 1483. Edward and his younger brother Richard of Shrewsbury, Duke of York, called the "Princes in the Tower", disappeared from the Tower of London around August 1483.

Henry VI, Part 2 (1591) is a Shakespearean history play about King Henry VI of England's inability to quell the bickering of his noblemen, the death of his trusted advisor Humphrey, Duke of Gloucester, and the political rise of Richard of York, 3rd Duke of York; it culminates with the First Battle of St Albans (1455), the initial battle of the Wars of the Roses, which were civil wars between the House of Lancaster and the House of York.

In the early historical narrative of Henry VI, Part 1 (1591), William Shakespeare deals with the low morale consequent to the loss of England's French territories (1429–1453) during the Hundred Years' War (1337–1453) and the political machinations that precipitated the Wars of the Roses (1455–1487). In the concluding play, Henry VI, Part 3 (1591), he deals with the fraternal horrors of civil war amongst Englishmen.

The House of Plantagenet (/plænˈtædʒɪnɪt/ plan-TAJ-in-it) was a royal house which originated in the French county of Anjou. The name Plantagenet is used by modern historians to identify four distinct royal houses: the Angevins, who were also counts of Anjou; the main line of the Plantagenets following the loss of Anjou; and the Houses of Lancaster and York, two of the Plantagenets' cadet branches. The family held the English throne from 1154, with the accession of Henry II, until 1485, when Richard III died in battle.

England was transformed under the Plantagenets, although only partly intentionally. The Plantagenet kings were often forced to negotiate compromises such as Magna Carta, which constrained royal power in return for financial and military support. The king was no longer just the most powerful man in the nation, holding the prerogative of judgement, feudal tribute and warfare, but had defined duties to the realm, underpinned by a sophisticated justice system. By the end of the reign of Edward III, the Plantagenets developed a new identity including adopting the language of the ordinary people—Middle English—as the language of governance. This is one of the reasons that the Oxford Dictionary of National Biography considers Edward III as culturally the first English Plantagenet ruler.

The House of Tudor (/ˈtjuː.dər/, TEW-dər) was an English and Welsh dynasty that held the throne of England from 1485 to 1603. They descended ultimately from Ednyfed Fychan and the Tudors of Penmynydd, a Welsh noble family, and Catherine of Valois. The Tudor monarchs were also descended from the House of Lancaster. They ruled the Kingdom of England and the Lordship of Ireland (later the Kingdom of Ireland) for 118 years with five monarchs: Henry VII, Henry VIII, Edward VI, Mary I and Elizabeth I. The Tudors succeeded the House of Plantagenet as rulers of the Kingdom of England, and were succeeded by the Scottish House of Stuart. The first Tudor monarch, Henry VII, descended through his mother from the House of Beaufort, a legitimised branch of the English royal House of Lancaster, a cadet house of the Plantagenets. The Tudor family rose to power and started the Tudor period in the wake of the Wars of the Roses (1455–1487), which left the main House of Lancaster (with which the Tudors were aligned) extinct in the male line.

Henry VII (a descendant of Edward III, and the son of Edmund Tudor, a half-brother of Henry VI) succeeded in presenting himself as a candidate not only for traditional Lancastrian supporters, but also for discontented supporters of their rival Plantagenet cadet House of York, and he took the throne by right of conquest. Following his victory at the Battle of Bosworth Field (22 August 1485), he reinforced his position in 1486 by fulfilling his 1483 vow to marry Elizabeth of York, daughter of King Edward IV and the heiress of the Yorkist claim to the throne, thus symbolically uniting the former warring factions of Lancaster and York under the new dynasty (represented by the Tudor rose). The Tudors extended their power beyond modern England, achieving the full union of England and the Principality of Wales in 1542 (Laws in Wales Acts 1535 and 1542), and successfully asserting English authority over the Kingdom of Ireland (proclaimed by the Crown of Ireland Act 1542). They also maintained the nominal English claim to the Kingdom of France; although none of them made substance of it, Henry VIII fought wars with France primarily as a matter of international alliances but also asserting claim to the title. After him, his daughter Mary I lost control of all territory in France permanently with the Siege of Calais in 1558.

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.
