"Warwick, the Kingmaker" by Charles Oman Richard Neville, 16th Earl of Warwick, known as Warwick the Kingmaker, was an English nobleman, administrator, and military commander. Warwick fought for the man he trained and helped make King of England, and then changed sides when he felt he had no choice. This book shows the character in a more sympathetic light, a stance much different than the one taken by many other historic texts.
