In the latest episode of History Gems, Dr Nicola Tallis is joined by Dr Ellie Woodacre, senior lecturer in early modern history at the University of Winchester and a specialist in queenship and royal studies, to discuss the Queen of England that you've probably never heard of - Joan of Navarre.

Born into Navarrese nobility, Joan became Queen of England after marrying Henry IV of England in 1403. But it wasn't all plain sailing as you'll find out if you listen! And as ever, there are gems and jewels to discuss along the way.
