Series 1, Episode 11: In this episode of The Royal Beat - Back In Time, delve into the lives of two cousins who both became King - Richard II and Henry IV. Find out what drove King Richard's increasingly erratic behaviour and uncover how his upbringing left him woefully ill-prepared to rule, compared to his cousin Henry who had everything he needed to be a great King - except a claim to the throne. Sarah Hewson presents the show and is joined by historians Dr Elizabeth Norton, Matt Lewis and Helen Castor whose book 'The Eagle and the Hart: The Tragedy of Richard II and Henry IV' explores the lives of these very different but equally interesting Kings.
