Overview
A kingmaker is a person or group that has great influence on a royal or political succession, without themselves being a viable candidate. Kingmakers may use political, monetary, religious, and military means to influence the succession. Originally, the term applied to the activities of Richard Neville, 16th Earl of Warwick—"Warwick the Kingmaker"—during the Wars of the Roses (1455–1487) in England.
