Edward Seymour, 1st Duke of Somerset, 1st Earl of Hertford, 1st Viscount Beauchamp KG, PC (1500^[1] – 22 January 1552), also known as Edward Semel,^[2] was an English nobleman and politician who served as Lord Protector of England from 1547 to 1549 during the minority of his nephew King Edward VI. He was the eldest surviving brother of Queen Jane Seymour, the third wife of King Henry VIII.

Seymour grew rapidly in favour with Henry VIII following Jane's marriage to the king in 1536, and was subsequently made Earl of Hertford. On Henry's death in 1547, he was appointed protector by the Regency Council on the accession of the nine-year-old Edward VI. Rewarded with the title Duke of Somerset, Seymour became the effective ruler of England. Somerset continued Henry's military campaign against the Scots and achieved a sound victory at the Battle of Pinkie, but ultimately he was unable to maintain his position in Scotland. Domestically, Somerset pursued further reforms as an extension of the English Reformation, and in 1549 imposed the first Book of Common Prayer through the Act of Uniformity, offering a compromise between Protestant and Roman Catholic teachings. The unpopularity of Somerset's religious measures, along with agrarian grievances, resulted in unrest in England and provoked a series of uprisings (including the Prayer Book Rebellion and Kett's Rebellion). Costly wars and economic mismanagement brought the Crown to financial ruin, further undermining his government.

In October 1549, Somerset was forced out of power and imprisoned in the Tower of London by John Dudley, Earl of Warwick, and a group of privy councillors. He was later released and reconciled with Warwick (now Duke of Northumberland), but in 1551 Northumberland accused him of treason, and he was executed in January 1552. Until the 1970s historians had a highly positive view of Somerset, seeing him as a champion of political liberty and the common people, but since then he has also often been portrayed as an arrogant and inept ruler of the Tudor state.
