Charles and his regency were incompetent in dealing with the War of Devolution that Louis XIV of France prosecuted against the Spanish Netherlands in 1667–68, losing considerable prestige and territory, including the cities of Lille and Charleroi. In the Franco-Dutch War of 1672–78, Spain lost still more territory when it joined an anti-French coalition, most notably Franche-Comté in Burgundy. In the War of the Reunions (1683–84), Louis XIV once again invaded the Spanish Netherlands, capturing Luxembourg following a brief siege. The war revealed to Europe the vulnerability of the Spanish defenses and bureaucracy. Furthermore, the ineffective Spanish Habsburg government took no action to improve them.
