Despite Henry's fame for the multiple wives he had, he really only had one male heir, Edward the sixth, who died at the age of 15 and two daughters who became Mary the 1st and Elizabeth the 1st of England
Henry proceeded to have three more wives after that, after the divorce or execution of the previous one. Anne of Cleves, Ctherine Howard and Catherine Parr, none of which supplied him with a second legitimate male.
Jane Seymour was Henry's third wife and is actually the only wife, who fulfilled Henry's desire for a male heir who later became Edward the sixth.
After Henry's request for a divorce with Catherine of Aragon was rejected by the pope, Henry broke away from the Roman Catholic church and formed his own church, the Church of England, where he was the new head and had all the church powers such as the ability to divorce and remarry, a process he has been known to do many times throughout his life.
Henry did not have only one wife but because of his desperation for a male heir he had six wives. He first had a marriage with Catherine of Aragon, however her inability to procure a son irritated Henry and as a result they were divorced with Anne Boleyn becoming Henry's new wife.
Henry was born on the 28th of June 1491 in Greenwich palace and was crowned king of England on the 24th of June 1509. In 1493, at the age of 2 however, Henry already became a constable of Dover castle and soon after became earl marshal of England.
