Richard has been greatly maligned since Tudor times, some of the Tudor reports having been written at the "request" of Henry VII in order to underline his claim to the throne. Richard was a fair and just king, introducing public education for all, and the jury system for common people. According to documents in the British Museum, the twins were still alive and well after Richard had been killed at Bosworth.
