Edward VI of England

Edward VI was crowned king of England at age nine, succeeding his father Henry VIII. His reign was dominated by regents, first Edward Seymour, Duke of Somerset, and later John Dudley, Duke of Northumberland.

Edward VI's government passed the Act of Uniformity, imposing the Book of Common Prayer in English. This reform advanced the Protestant Reformation in England, replacing Latin services with English ones and standardizing worship.

Edward VI's government issued the Forty-Two Articles, defining the doctrinal basis of the Church of England. These articles were more Protestant than earlier reforms, but were repealed after Edward's death under Mary I.

Edward VI, on his deathbed, drafted a will excluding his half-sisters Mary and Elizabeth from the succession, naming Lady Jane Grey as his heir. This attempt to maintain Protestant rule failed after his death, leading to Mary I's accession.
