 Pole is known to have said that he would "never fear to call himself the son of a martyr".Some 350 years later, in 1886, Margaret was beatified by Pope Leo XIII.Aside from the aforementioned oppositional treatise, King Henry's harshness towards the Pole family might have derived from the fact that Pole's mother, Margaret, was one of the last surviving members of the House of Plantagenet.
