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.
