The "Bal des Ardents" added to the impression of a court steeped in extravagance, with a king in delicate health and unable to rule. Charles's attacks of illness increased in frequency such that by the end of the 1390s his role was merely ceremonial. By the early 15th century he was neglected and often forgotten, a lack of leadership that contributed to the decline and fragmentation of the Valois dynasty. In 1407, Philip the Bold's son, John the Fearless, had his cousin Orléans assassinated because of "vice, corruption, sorcery, and a long list of public and private villainies"; at the same time Isabeau was accused of having been the mistress of her husband's brother. Orléans's assassination pushed the country into a civil war between the Burgundians and the Orléanists (known as the Armagnacs), which lasted for several decades. The vacuum created by the lack of central power and the general irresponsibility of the French court resulted in it gaining a reputation for lax morals and decadence that endured for more than 200 years.
