Richard Neville, Earl of Warwick in the context of "Wars of the Roses"

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.

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 Second Battle of St Albans was fought on 17 February 1461 during the Wars of the Roses in St Albans, Hertfordshire, England (the First Battle of St Albans had been fought in 1455).

The army of the Yorkist faction, under the Earl of Warwick, attempted to bar the road to London north of the town. The rival Lancastrian army used a wide outflanking manoeuvre to take Warwick by surprise, cut him off from London and drive his army from the field. The victors also released the feeble King Henry VI, who had been Warwick's prisoner, from his captivity, but they ultimately failed to take advantage of their victory.
