Before World War I, many aristocratic Hungarian families (such as Esterházy, Batthyany and Pálffy) had their own palaces in Vienna, where their king (the Emperor of Austria) resided.
Politicians and generals of both leading nations, Austrian Germans and Magyar Hungarians, were responsible for the disastrous foreign policy of the Monarchy that led towards World War I. Thence these two were treated as defeated enemies after World War I by the Allies of World War I.
