Charles V and du Guesclin diesToulouse, France
Charles V died on 16 September 1380 and Du Guesclin died of illness at Châteauneuf-de-Randon while on a military expedition in Languedoc. France lost its main leadership and overall momentum in the war. Charles VI succeeded his father as king of France at the age of 11, and he was thus put under a regency led by his uncles, who managed to maintain an effective grip on government affairs until about 1388, well after Charles had achieved royal majority.
With France facing widespread destruction, plague, and economic recession, high taxation put a heavy burden on the French peasantry and urban communities. The war effort against England largely depended on royal taxation, but the population was increasingly unwilling to pay for it, as would be demonstrated at the Harelle and Maillotin revolts in 1382. Charles V had abolished many of these taxes on his deathbed, but subsequent attempts to reinstate them stirred up hostility between the French government and populace.
