Lady Jane Grey, the great-granddaughter of Henry VII and a first cousin once removed of Edward VI was named by the 15-year-old king Edward VI as his successor in June 1553. Mary Tudor - a staunch Catholic - immediately took steps against the Protestant Jane and after nine days imprisoned her in the Tower. When Mary announced her plans to marry Philip of Spain, she also ordered the execution of Jane and her husband and the order was carried out on 12. February 1554.
