A friend kindly forwarded to me the link to an article in the BBC Magazine about the way in which Maurice Druon's set of seven novels The Accursed Kings (Les Rois Maudits), about the last Capetian Kings of France and the origins of the Hundred Year War were an inspiration for the currently very popular Game of Thrones novels of George R. R. Martin and the television series based thereupon. It can be read here.
I do not know, other than by name, The Game of Thrones series, with its Tolkienesque setting. However I do esteem the Druon novels, and the original 1973-4 ORTF tv production - you can find the six dramas on YouTube - and I am delighted to see that the novels are being reissued.
The Accursed Kings

In addition the novels have a series of historical endnotes to accompany their interpretation of events. Druon was writing with dramatic effect in mind, and he does exercise artistic freedom at times, but not such as to reduce the historic credibility of the books. One may question the interpretation he gives of some of the figures - notably King Louis X and King Charles IV - but the novels are a thoroughly good introduction to the period and a wonderful evocation of medieval political machinations.
