During the years 1764 to 1770 he took a series of government posts in a variety of foreign locations: Switzerland, Italy, Malta, Germany, the Netherlands, France, Spain, Portugal, the British Isles, and Belgium. He spent the years 1770–76 in Vienna, whereupon he took up a new position (1776–81) as governor of
Trieste. He was responsible for building the road between Trieste and Vienna (named in his honor by the town Zinzendorf). As
privy finance minister (President of the Court Audit Office) to Emperor
Joseph II between 1782 and 1792 von Zinzendorf introduced a uniform system of accounting for state revenues, expenditures, and debts of the territories of the Austrian crown, called
Appalt. Austria was more successful than France in meeting regular expenditures and in gaining credit. However, the events of Joseph II's last years also suggest that the government was financially vulnerable to
the European wars that ensued after 1792. ==Death==
