The beginning of the Seven Years’ War in 1757 thwarted the development of many of the reforms. In false defense of his failing policies, Haugwitz argued that the reforms “were only for peacetime”. Eventually, Haugwitz's "Directorium" was stripped of its military and financial functions and renamed the Bohemian and Austrian Court Chancellery. Most power now became centered in the Council of State headed by Wenzel Anton Graf Kaunitz. Kaunitz, a historic foe of Haugwitz, replaced him in instituting policies. However, Haugwitz's policies would have an effect throughout the reign of Maria Theresa and later in the reign of Joseph II.
