The Austrian emperors had an extensive list of titles and claims that reflected the geographic expanse and diversity of the lands ruled by the Austrian Habsburgs. The grand title of the emperor of Austria had been changed several times: by a patent of 1 August 1804, by a court office decree from 22 August 1836, by an Imperial court ministry decree of 6 January 1867 and finally by a letter of 12 December 1867. Shorter versions were recommended for official documents and international treaties: "Emperor of Austria, King of Bohemia etc. and Apostolic King of Hungary", "Emperor of Austria and Apostolic King of Hungary", "His Majesty the Emperor and King" and "His Imperial and Royal Apostolic Majesty".
