Besides his six marriages, Henry VIII is known for his role in the separation of the Church of England from the Roman Catholic Church, says Wikipedia.
Henry's struggles with Rome led to the separation of the Church of England from papal authority, the Dissolution of the Monasteries, and establishing himself as the Supreme Head of the Church of England.
Henry was known by some to be an attractive and charismatic man in his prime, educated and accomplished.[4] He was an author and a composer. He ruled with absolute power.
His desire to provide England with a male heir—which stemmed partly from personal vanity and partly because he believed a daughter would be unable to consolidate the Tudor Dynasty and the fragile peace that existed following the Wars of the Roses[5]—led to the two things that Henry is remembered for: his wives, and the English Reformation that made England a mostly Protestant nation. In later life he became morbidly obese and his health suffered; his public image is frequently depicted as one of a lustful, egotistical, harsh, and insecure king.[6]
Financially, the reign of Henry was a near-disaster. Although he inherited a prosperous economy (and further augmented his royal treasury by seizures of church lands), Henry's heavy spending and high taxes damaged the economy.
[15][16] For example, Henry expanded the Royal Navy from 5 to 53 ships. He loved palaces; he began with a dozen and died with fifty-five, in which he hung 2,000 tapestries. He took pride in showing off his collection of weapons, which included exotic archery equipment, 2,250 pieces of land ordinance and 6,500 handguns.[19]
Henry worked hard to present an image of unchallengeable authority and irresistible power. He executed at will, beheading, often in public, more English notables than any monarch before or since. The roll of heads included two wives, twenty peers, four leading public servants, and six of the king's close attendants and friends, not to mention one cardinal and various heads of monasteries. In addition Cardinal Wolsey died en route to his treason trial.
A big, strong man (over six feet tall and broad in proportion), he excelled at jousting and hunting. More than pastimes, they were political devices that served multiple goals, from enhancing his athletic royal image to impressing foreign emissaries and rulers, to conveying Henry's ability to suppress any rebellion.
