Passage: Henry VIII died in 1547 and Elizabeth's half-brother, Edward VI, became king at age nine. Catherine Parr, Henry's widow, soon married Thomas Seymour, 1st Baron Seymour of Sudeley, Edward VI's uncle and the brother of the Lord Protector, Edward Seymour, 1st Duke of Somerset. The couple took Elizabeth into their household at Chelsea. There Elizabeth experienced an emotional crisis that some historians believe affected her for the rest of her life. Thomas Seymour, approaching age 40 but having charm and "a powerful sex appeal", engaged in romps and horseplay with the 14-year-old Elizabeth. These included entering her bedroom in his nightgown, tickling her and slapping her on the buttocks. Parr, rather than confront her husband over his inappropriate activities, joined in. Twice she accompanied him in tickling Elizabeth, and once held her while he cut her black gown "into a thousand pieces." However, after Parr discovered the pair in an embrace, she ended this state of affairs. In May 1548, Elizabeth was sent away.
