Henry VIII was King of England from 1509 until his death. Henry was the second Tudor monarch, succeeding his father, Henry VII.
Henry is best known for his six marriages, in particular his efforts to have his first marriage, to Catherine of Aragon, annulled. His disagreement with the Pope on the question of such an annulment led Henry to initiate the English Reformation, separating the Church of England from papal authority. He appointed himself the Supreme Head of the Church of England and dissolved convents and monasteries, for which he was excommunicated.
Domestically, Henry is known for his radical changes to the English Constitution, ushering into England the theory of the divine right of kings. Besides asserting the sovereign's supremacy over the Church of England, he greatly expanded royal power during his reign. Charges of treason and heresy were commonly used to quell dissent, and those accused were often executed without a formal trial, by means of bills of attainder. He achieved many of his political aims through the work of his chief ministers, some of whom were banished or executed when they fell out of his favour.
