Little Jack Horner II by AMIT with Dan Roberts published on 2016-06-29T14:52:05Z To get his hands on the monastic lands of Glastonbury Cathedral in 1539, King Henry VIII of England relied on the treachery of the Abbot's assistant, Thomas Horner. To secure his family's lock on the English throne, Henry VIII felt he had to have a male heir. Since his first wife, Catherine of Aragon, had failed to produce a son, he divorced her. To do so meant England had to renounce the jurisdiction of the Roman Catholic Pope. Henry became the Supreme Head of the Church and then, beginning in 1536, started closing the monasteries, many of which were lingering hotbeds of Catholic sentiment in England.
