Two years later, when Richard III was defeated at the Battle of Bosworth (1485), he was attainted for rebelling against the King.

Context_3 : Ricardians are people interested in altering the posthumous reputation of Richard III, King of England (reigned 1483–1485).

Ricardians have worked in an effort to turn this around and to paint this portrayal, and the many other related assertions that followed, as most probably false politically motivated accusations.

He was the first Yorkist King of England. The first half of his rule was marred by the violence associated with the Wars of the Roses, but he overcame the Lancastrian challenge to the throne at Tewkesbury in 1471 to reign in peace until his sudden death.
