Rudolph's brothers Albert III and Leopold III ignored their father Rudolph IV’s to preserve the integrity of his domains, and enacted the separation of the so-called Albertinian and Leopoldian family lines on by the Treaty of Neuberg. The former would maintain Austria proper (then called "Niederösterreich" but comprising modern Lower Austria and most of Upper Austria), while the latter would rule over lands then labeled "Oberösterreich", namely Inner Austria ("Innerösterreich") comprising Styria, Carinthia and Carniola, and Further Austria ("Vorderösterreich") consisting of Tyrol and the western Habsburg lands in Alsace and Swabia.
