The derogatory expression "Mad War" to designate this struggle of major feudal lords against central royal power was coined by Paul Emile in his Histoire des faicts, gestes et conquestes des roys de France, published in 1581. There is some dispute about the extent to which the events can be defined as a single war. It followed a long succession of conflicts between royalty and the great lords of the kingdom in the second half of the 15th century, subsequent to the formation of the League of the Public Weal. As part of these power struggles, in 1484-1485, Louis II of Orléans, supported by Francis II of Brittany and a certain number of lords, attempted to depose the regent, Anne de Beaujeu. Mostly by a mixture of diplomacy and shows of force, Anne succeeded in breaking the revolt without a major battle. On 2 November 1485, the Peace of Bourges suspended the hostilities. According to some historians, this ended the first phase of the "Mad War." The second phase of the conflict, from June 1486 to November 1488, is sometimes called the War of Brittany. Other commentators, mainly Breton nationalists, distinguish this second phase from the first, making it into a Franco-Breton war, or even a Breton war of independence, sometimes by connecting it to the earlier Breton War of Succession.
