Lady Jane Grey, born on October 12, 1537, also known as "The Nine Days Queen," was an English noblewoman who briefly served as queen of England from 10 July to 19 July 1553. Her reign was unsuccessful, and she was subsequently executed by decapitation the following year on February 12, 1554, at the age of 17, charged with high treason.
Jane was born in London, or at her family home of Bradgate Park, Leicestershire, England.[2] She was great-granddaughter of Henry VII by his younger daughter Mary, and a first-cousin-once-removed of Edward VI.
In May 1553, Jane married Lord Guildford Dudley, a younger son of Edward's chief minister, John Dudley, Duke of Northumberland. When the 15-year-old King lay dying in June 1553, he nominated Jane as successor to the Crown in his will, thus subverting the claims of his half-sisters Mary and Elizabeth.
During her short reign, Jane lived in the Tower of London. She became a prisoner there, as the Privy Council decided to change sides and proclaim Mary as queen, on 19 July 1553. Wyatt's rebellion in January and February 1554 against Queen Mary's plans of a Spanish match was the direct cause of Jane's and her husband's execution.
