To illustrate some of the political upheaval due to the Black Death, a good example Cantor uses is the story of the Plantagenets. If the Black Death had not killed so many peasants who made up the army, the Plantagenets may have become kings of France (p. 214). Ten years before the plague, about sixty percent of wealth and almost all political power in Western Europe lie in the hands of about three hundred noble families (p. 59). The nobles employed thousands of workers, and the Plantagenet family in England lived in luxury (p. 61). King Edward III of England wanted to expand his holdings, and planned to marry his daughter, Joan, to Pedro, the son of King Alfonso of Castile. Joan tragically died of the plague in Bordeaux, which was devastated by the Black Death (p. 37, 47). Edward's other daughter was already married, and Edward's hopes to have the Plantagenet line "prevail in Spain as in England, Wales and France" (p. 37) were dashed.
Cantor links the plague to the War of the Roses. Edward's son, John of Gaunt, was married to Blanch Grosmont, who inherited her father's huge estate when he died of the plague (p.56). John of Gaunt became duke of Lancaster, which gave him as much power as the rest of the family. John of Gaunt's heir, Henry of Lancaster, seized the crown from his cousin, Richard
II. The rest of the family sided with the Duke of York, who was a descendant of Edward III's son, Edmund of Langley. This started the War of the Roses,
