While Frederick sought to be elected German king against his Welf rival Otto IV, he had his new-born son crowned King of Sicily (as Henry II) by Pope Innocent III in March 1212, since an agreement between Frederick and the Pope stated that the kingdoms of Germany and Sicily should not be united under one ruler. For this, the regency of the Sicilian kingdom went to his mother Constance and not to his father. However, after the death

Title: Henry VII of England
Content:  Henry VII (Harri Tudur; 28 January 1457 – 21 April 1509) was King of England and Lord of Ireland from his seizure of the crown on 22 August 1485 until his death in 1509. He was the first monarch of the House of Tudor. Henry's mother, Margaret Beaufort, was a descendant of the Lancastrian branch of the House of Plantagenet. Henry's father, Edmund Tudor, 1st Earl of Richmond, a half-brother of Henry VI of England and descendant of the Welsh Tudors of Penmynydd, died three months before his son Henry was born. During Henry's early years, his uncle Henry VI was fighting against Edward IV, a member of the Yorkist Plantagenet branch.

He attained the throne when his forces, supported by France, Scotland, and Wales, defeated Edward IV's brother Richard III 
Title: Henry VIII
Content:  Upon Henry's death, he was succeeded by his son Edward VI. Since Edward was then only nine years old, he could not rule directly. Instead, Henry's will designated 16 executors to serve on a council of regency until Edward reached 18. The executors chose Edward Seymour, 1st Earl of Hertford, Jane Seymour's elder brother, to be Lord Protector of the Realm. If Edward died childless, the throne was to pass to Mary, Henry VIII's daughter by Catherine of Aragon, and her heirs. If Mary's issue failed, the crown was to go to Elizabeth, Henry's daughter by Anne Boleyn, and her heirs. Finally, if Elizabeth's line became extinct, the crown was to be inherited by the descendants of Henry VIII's deceased younger sister, Mary, the Greys. The descendants of Henry's sister Margaret—the Stuarts, rulers of Scotland—were thereby excluded from the succession. This provision ultimately failed when James VI of Scotland became King of England in 1603.
