Document 5: Ricardian (Richard III): Ricardians are people interested in altering the posthumous reputation of Richard III, King of England (reigned 1483–1485). Richard III has long been portrayed unfavourably, most notably in William Shakespeare's play "Richard III", in which Richard is portrayed as having murdered his nephew, the crown prince of England, a 12 year old child at the time, in order to secure the English throne for himself. 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.

It depicts the Machiavellian rise to power and subsequent short reign of King Richard III of England. The play is grouped among the histories in the First Folio and is most often classified as such.
