Henry IV, Part 1

Henry Bolingbroke (now King Henry IV) is having an unquiet reign. His personal disquiet at the usurpation of his predecessor Richard II would be solved by a crusade to the Holy Land, but broils on his borders with Scotland and Wales prevent that. Moreover, he is increasingly at odds with the Percy family, who helped him to his throne, and Edmund Mortimer, the Earl of March, Richard II's chosen heir.
