Richard III (1483-1485) was the younger brother of Edward IV. He is marked in history as the murderer of his nephews 'the Princes in the Tower' but no one knows if this is true.
When Richard became king, the War of the Roses was still raging, with Lancastrians trying to take the throne away from the Yorks. In 1585 the Richard III met the Lancastrian Henry Tudor at the Battle of Bosworth Field. Richard was killed in the battle. It is believed that Henry Tudor (Henry VII) was crowned on the battlefield with Richard's bloodstained crown.
The history of Richard III is mixed up with Tudor propaganda, much from the pen of William Shakespeare, so no-one is quite sure about the truth regarding this king, who was the last Yorkist and the last Plantaganet. In 2012, Richard III's bones were found in a carpark in Leicester and were moved to a more proper place in Leicester Cathedral in 2015.
