Why did Richard III make himself king in 1483?
Richard, Duke of Gloucester, had no ambition for the throne before Edward IV’s early death and the accession of his 12 year old son. Before this Richard had served his brother ably and loyally, it was only when he died and Richard did not get the throne straight away that Richard started to get angry and determined to get the throne to himself. A key reason, for Richard to usurp the throne is that he had the character and means to take such action – he was ruthless and determined, had powerful allies including Hastings and Buckingham, and seized the opportunities when they arose, and he took those chances and grasped them with both hands.
