(1537-1553) king of England and Ireland from 1547, son of Henry VIII
and his third wife, Jane Seymour
. Since Edward was only ten years old at the time of the coronation, the government was first entrusted to a lord protector, the king's uncle, Edward Seymour, Duke of Somerset, who was executed in 1552 and replaced by John Dudley, Earl of Warwick and Duke of Northumberland. The king's health, never robust, deteriorated in 1553 and Northumberland made efforts to induce the dying boy to alter the succession in favour of his own daughter-in-law, Lady Jane Grey.
