John, Duke of Bedford in the context of "Joan of Arc"

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 siege of Orléans (12 October 1428 – 8 May 1429) marked a turning point of the Hundred Years' War between France and England. The siege took place at the pinnacle of English power during the later stages of the war, but was repulsed by French forces inspired by the arrival of Joan of Arc. The French would then regain the initiative in the conflict and began to recapture territories previously occupied by the English.

The city held strategic and symbolic significance to both sides of the conflict. The consensus among contemporaries was that the English regent, John of Lancaster, would have succeeded in realising his brother the English king Henry V's dream of conquering all of France if Orléans fell. For half a year the English and their French allies appeared to be on the verge of capturing the city, but the siege collapsed nine days after Joan of Arc arrived.

Humphrey of Lancaster, Duke of Gloucester (3 October 1390 – 23 February 1447) was an English prince, soldier and literary patron. He was, and styled himself as, "son, brother and uncle of kings", being the fourth and youngest son of Henry IV of England, the brother of Henry V, and the uncle of Henry VI. Gloucester fought in the Hundred Years' War and acted as Lord Protector of England during the minority of his nephew. A controversial figure, he has been characterised as reckless, unprincipled, and fractious, but is also noted for his intellectual activity and for being the first significant English patron of humanism, in the context of the Renaissance.

Unlike his brothers, Humphrey was given no major military command by his father, instead receiving an intellectual upbringing. Created Duke of Gloucester in 1414, he participated in Henry V's campaigns during the Hundred Years' War in France: he fought at Agincourt in 1415 and at the conquest of Normandy in 1417–9. Following the king's death in 1422, Gloucester became one of the leading figures in the regency government of the infant Henry VI. He proved a rash, impulsive, unscrupulous and troublesome figure, he quarrelled constantly with his brother, John, Duke of Bedford and uncle, Cardinal Henry Beaufort and went so far as to violently prosecute a dispute with the Duke of Burgundy, a key English ally in France, over conflicting claims to lands in the Low Countries.

John Dunstaple (or Dunstable; c. 1390 – 24 December 1453) was an English composer whose music helped inaugurate the transition from the medieval to the Renaissance periods. The central proponent of the Contenance angloise style (lit. 'English manner'), Dunstaple was the leading English composer of his time, and is often coupled with William Byrd and Henry Purcell as England's most important early music composers. His style would have an immense influence on the subsequent music of continental Europe, inspiring composers such as Du Fay, Binchois, Ockeghem and Busnois.

Information on Dunstaple's life is largely non-existent or speculative, with the only certain date of his activity being his death on Christmas Eve of 1453. Probably born in Dunstable in Bedfordshire during the late 14th-century, Dunstaple was associated with Humphrey, Duke of Gloucester and Joan of Navarre, and, through them, St Albans Abbey. Another important patron was John, Duke of Bedford, with whom Dunstaple may have travelled to France.
