Henry VII. He was crowned after the Battle of Bosworth Field. Henry’s rival, Richard III, had been killed in the battle and his battered gold circlet crown was found by Sir Richard Bray, who rushed it to Crown Hill where the new king had gathered his surviving troops. The crown was handed to Henry who placed it on his own head while his troops cried out: "King Henry, King Henry!" again and again.
