Document 2: The Wars of the Roses (adaptation): The Wars of the Roses was a 1963 theatrical adaptation of William Shakespeare's first historical tetralogy ("1 Henry VI", "2 Henry VI", "3 Henry VI" and "Richard III"), which deals with the conflict between the House of Lancaster and the House of York over the throne of England, a conflict known as the Wars of the Roses. The plays were adapted by John Barton, and directed by Barton himself and Peter Hall at the Royal Shakespeare Theatre. The production starred David Warner as Henry VI, Peggy Ashcroft as Margaret of Anjou, Donald Sinden as the Duke of York, Paul Hardwick as the Duke of Gloucester, Janet Suzman as Joan la Pucelle, Brewster Mason as the Earl of Warwick, Roy Dotrice as Edward IV, Susan Engel as Queen Elizabeth and Ian Holm as Richard III.
Document 3: Henry Somerset, 1st Duke of Beaufort: Henry Somerset, 1st Duke of Beaufort, KG, PC (1629 – 21 January 1700) was a Welsh politician who sat in the House of Commons at various times between 1654 and 1667, when he succeeded his father as 3rd Marquess of Worcester. He was styled Lord Herbert from 1644 until 3 April 1667. The Dukedom of Beaufort was bestowed upon him by King Charles II in 1682.

Document 5: Capetian-Plantagenet rivalry: The conflict between the dynasties of the Capetians and Plantagenets covers a period of 100 years (1159-1259), during which the Kingdom of France fought against the Angevin Empire. This conflict is also called by some historians, the "First Hundred Years War." The conflict is primarily French, since both dynasties were French, the nobles that made up the English army were essentially of French origin, and the foot soldiers of the English king were local recruits in France (Anjou, Guyenne, Normandy, Brittany etc.). At this period, the English king's continental possessions were considered more important than his island possessions, and significantly greater than even those of the French sovereign, even if the latter was the overlord of the former for most of the possessions he held on the continent. And the official language of the two belligerents is the French of that time. French also remained the official language of England until 1361. Such is the origin of the expressions that can still be found today on the shields and coat of arms of the English monarchy "Honi soit qui mal y pense" and "Dieu et mon droit". The English kings, who were of French origin, took wives from France from the 11th to the 15th century. Very rare are those who married a woman of another country, including the cadet branches. Hence the Plantagenet monarchs were ethnically French.
Document 6: Charles Somerset, 1st Earl of Worcester: Charles Somerset, 1st Earl of Worcester, (c. 1460 – 15 March 1526) was an English nobleman and politician. He was the legitimised bastard son of Henry Beaufort, 3rd Duke of Somerset by his mistress Joan Hill.
Document 7: War of the Roses (Pennsylvania): The South Central Pennsylvania cities of Lancaster and York have a historical rivalry in all sporting events from the high-school level to the professional. Since both cities are named after the English cities of Lancaster and York, the former Pennsylvania baseball teams were named for the opposing sides of the Wars of the Roses. As a metaphor, "War of the Roses" describes the intense baseball matches fought between the Lancaster Red Roses and the York White Roses. With the addition of York to the Atlantic League, the Barnstormers continue the Red Roses' tradition as they battle the York Revolution for lower Susquehanna supremacy.
Document 8: Thomas Neville (died 1460): Sir Thomas Neville, (c. 1429–1460) was the second son of Richard Neville, 5th Earl of Salisbury, a major magnate in the north of England during the fifteenth-century Wars of the Roses, and a younger brother to the more famous Richard Neville, Earl of Warwick, known as the 'Kingmaker.' Thomas worked closely with them both in administering the region for the Crown, and became a significant player in the turbulent regional politics of Northern England in the early 1450s. His wedding in August 1453 marked the beginning of his family's armed feud with their rivals, the House of Percy, in which Thomas and his brother John led a series of raids, ambushes and skirmishe across Yorkshire against the Percys. Many historians describe the feud as the beginning of the Wars of the Roses, a series of dynastic struggles in mid-fifteenth century England, and Thomas Neville played a large role in his father's alliance with Thomas's uncle, Richard, 3rd Duke of York.
Document 9: Duke of Beaufort: Duke of Beaufort, a title in the Peerage of England, was created by Charles II in 1682 for Henry Somerset, 3rd Marquess of Worcester, a descendant of Charles Somerset, 1st Earl of Worcester, legitimized son of Henry Beaufort, 3rd Duke of Somerset, a Lancastrian leader in the Wars of the Roses. The name "Beaufort" refers to a castle in Champagne, France (now Montmorency-Beaufort). It is the only current dukedom to take its name from a place outside the British Isles.
Document 10: House of York: The House of York was a cadet branch of the English royal House of Plantagenet. Three of its members became Kings of England in the late 15th century. The House of York was descended in the male line from Edmund of Langley, 1st Duke of York, the fourth surviving son of Edward III, but also represented Edward's senior line, being cognatic descendants of Lionel, Duke of Clarence, Edward III's second surviving son. It is based on these descents that they claimed the English crown. Compared with the House of Lancaster, it had a senior claim to the throne of England according to cognatic primogeniture but junior claim according to the agnatic primogeniture. The reign of this dynasty ended with the death of Richard III of England in 1485. It became extinct in the male line with the death of Edward Plantagenet, 17th Earl of Warwick in 1499.
Document 11: House of Plantagenet: The House of Plantagenet ( ) was a royal house which originated from the lands of Anjou in France. The name Plantagenet is used by modern historians to identify four distinct royal houses – the Angevins who were also Counts of Anjou, the main body of the Plantagenets following the loss of Anjou, and the houses of Lancaster and York, the Plantagenets' two cadet branches. The family held the English throne from 1154, with the accession of Henry II, until 1485, when Richard III died.
Document 12: Henry Beaufort, 3rd Duke of Somerset: Henry Beaufort, 3rd Duke of Somerset (26 January 1436 – 15 May 1464) was an important Lancastrian military commander during the English Wars of the Roses. He is sometimes numbered the 2nd Duke of Somerset, because the title was re-created for his father after his uncle died. He also held the subsidiary titles of 5th Earl of Somerset, 2nd Marquess of Dorset and 2nd Earl of Dorset.
Document 13: Edmund Beaufort, 2nd Duke of Somerset: Edmund Beaufort, 2nd Duke of Somerset, KG (1406 – 22 May 1455), sometimes styled 1st Duke of Somerset, was an English nobleman and an important figure in the Wars of the Roses and in the Hundred Years' War. He also succeeded in the title of 4th Earl of Somerset and was created 1st Earl of Dorset and 1st Marquess of Dorset (previously held by his father and later forfeited), and Count of Mortain. He was known for his deadly rivalry with Richard Plantagenet, 3rd Duke of York.
Document 14: Wars of the Roses: The Wars of the Roses were a series of wars for control of the throne of England fought between supporters of two rival branches of the royal House of Plantagenet: the House of Lancaster (associated with a red rose), and the House of York (whose symbol was a white rose). The conflict lasted through many sporadic episodes between 1455 and 1487; however, there was fighting before and after this period between the houses. The power struggle ignited around social and financial troubles following the Hundred Years' War, combined with the mental infirmity and weak rule of Henry VI which revived interest in Richard of York's claim to the throne. Historians disagree about whether the Wars of the Roses were caused by the structural problems of feudalism or Henry VI's ineffectiveness as king.
Document 15: Henry Beaufort: Henry Beaufort (c. 1375 – 11 April 1447) was a medieval English clergyman, Bishop of Winchester, a member of the royal house of Plantagenet, and a Cardinal of the Roman Catholic Church.
