The Accursed Kings by Maurice Druon is a series of seven historical novels that detail the destruction of the Knights Templar, then the subsequent deaths of Phillip the Fair and his sons, the ensuing succession crises and the beginning of the Hundred Year War, set up against the backdrop of France spiraling down into a veritable Crapsack World after it gets hit by disaster after disaster. The visceral B-plot of Robert D'Artois and his attempts to (re)gain his father's county also gets a lot of attention, to the point where it can hardly even be called secondary, and there are other minor plots which are intertwined with the two major ones and each other. While the period is described (quite aptly) as France's Darkest Hour, there is a lot of Black Comedy and ham involved.
