John Richard Green, History of the English People, Volume III
“ The Duke of Buckingham stood first in blood as in power among the English nobles; he was the descendant of Edward the Third's youngest son, and if Mary's succession were denied he stood heir to the throne. His hopes had been fanned by prophets and astrologers, and wild words told his purpose to seize the crown on Henry's death in defiance of every opponent. But word and act had for two years been watched by the king; and in 1521 the Duke was arrested, condemned as a traitor by his peers, and beheaded on Tower Hill. His blood was a pledge of Henry's sincerity which Charles could not mistake. ”
