The history of Austria covers the history of Austria and its predecessor states, from the early Stone Age to the present state. The name "Ostarrîchi" (Austria) has been in use since 996 AD when it was a margravate of the Duchy of Bavaria and from 1156 an independent duchy (later archduchy) of the Holy Roman Empire of the German Nation ("Heiliges Römisches Reich" 962–1806).
