Considering the high personal profile and influence of Isabeau of Bavaria during her time as queen of France between 1385 and 1422, it is extraordinary that she has not been the subject of more sustained serious academic study in the past, and that so little is known about her. The woman at the centre of such a turbulent period of Anglo-French war and internal conflict is far too often dismissed in the space of a few paragraphs; even then, what is written about her is often one-sided, two-dimensional and, in many cases, plain wrong. The history of Isabeau of Bavaria so far has largely been a fabricated mixture of gossip and propaganda which has been absorbed into historical tradition and repeated so often that, to many, legend has become indistinguishable from fact. For a mere two decades it has been accepted that: ‘Isabeau ne mérite point la réputation qui lui fut faite’, and it cannot be a coincidence that the few historians who have devoted any time to research on Isabeau all have come to the conclusion that her infamous legacy is not deserved. Yet, the movement for Isabeau of Bavaria's rehabilitation has not been as prominent as it might have been: Vallet de Viriville only wrote a few articles about her, Marcel Thibault never produced the promised second part of his biography and Yann Grandeau sadly died before his research papers could be developed into a complete work. The very first line that Thibault wrote in 1901 makes the claim that: ‘L'histoire vraie et complète d'Isabeau de Bavière n'a jamais été ecrite’ and, despite recent scholarly work, this still seems to be die case almost a century later.
