After Austria was detached from the
Duchy of Bavaria and established as an Imperial estate in 1156 (thanks to the
Privilegium Minus), the
Babenberg dukes also acquired the neighbouring
Duchy of Styria in 1192. After the extinction of male line in 1246 and the subsequent quarter-century reign by King
Ottokar II of Bohemia – a permanent vestige of his rule is the division of Austria proper into Upper and Lower Austria (at the time called "Austria above the
Enns" and "below the Enns") – it was seized by Habsburg King
Rudolf I of Germany, who defeated Ottokar in the
Battle on the Marchfeld (1278) and later (1282) enfeoffed his sons
Albert I and
Rudolf II with both duchies. In 1358/1359, Austrian Duke
Rudolf IV, in response to the
Golden Bull of 1356, already claimed the
archducal title by forging the
Privilegium Maius. Rudolf aimed to achieve a status comparable to the Empire's seven
prince-electors, the holders of the traditional Imperial
'arch'-offices; however, his attempts failed as the elevation was rejected by the
Luxembourg emperor
Charles IV (Rudolf's father-in-law). Rudolf's younger brothers
Albert III and
Leopold III divided the Habsburg lands by the 1379
Treaty of Neuberg, whereafter the Austrian duchy itself remained under the rule of the
Albertinian line. File:Niederösterreichische Landesausstellung 2019 - Friedrich V.jpg|Depiction of the archducal crown in a portrait of
