England's Empty Throne by Paul Strohm

After the dethronement and subsequent murder of Richard II, the usurping Lancastrian dynasty faced an exceptional challenge. Interrupting a long period of Plantagenet rule, Henry IV and Henry V needed not only to establish physical possession of the English throne, but to occupy it symbolically as well. 

In this boldly revisionary book [England's Empty Throne: Usurpation and the Language of Legitimation, 1399-1422], Paul Strohm provides a new account of the Lancastrian revolution and its aftermath. Integrating techniques of literary and historical analysis, he explores the new dynasty`s quest for legitimacy and the importance of symbolic activity to the making of kingship.

Strohm reveals the Lancastrian monarchs as masters of outward display, persuasively "performing" their kingship in a variety of novel ceremonies. Henry IV is crowned with a newly discovered coronation oil. The murdered Richard II is elaborately reburied. Opinion is courted and deceived with invented chronicles, false prophecies, and bogus genealogies. Opponents of the new regime are subject to new varieties of trial and punishment. Far-reaching Lancastrian experiments in domination include the proscription of prophecy, the enlistment of poetry, the use of spies and hired informers, and, most ambitiously, the redefinition of treason to cover not only overt deeds but also things said and even thought. 

Strohm`s account of the Lancastrian quest for legitimacy and the uses of symbolic power illuminates—indeed recasts—our understanding of a period of unprecedented political upheaval.
