Habsburg monarchy (1720–1805) From 1664/69 the Privy Conference (
Geheime Konferenz), a committee of the Imperial
Privy Council (
Geheimer Rat), provided advice to
Emperor Leopold I whereby the
Austrian Court Chancellor, responsible for the
Habsburg '
Hereditary Lands', served as
rapporteur and thereby gained increasing influence. The Habsburg diplomatic service was re-organised, when Emperor
Charles VI by resolution of 1720 declared Court Chancellor
Philipp Ludwig Wenzel von Sinzendorf responsible for foreign policy issues. Upon Sinzendorf's death in February 1742, Archduchess
Maria Theresa finally separated the central Habsburg State Chancellery responsible of Foreign Affairs from the domestic Austrian Court Chancellery.
