The Three Richards: Richard I, Richard II and Richard III | Nigel Saul
The three Richards who ruled England in the Middle Ages were among the most controversial and celebrated of its rulers. This biography shows how much the three kings had in common, apart from their names. All were younger sons, not expected to come to the throne; and all failed to leave a legitimate heir, causing instability on their deaths.
