Tension developed between the brothers, and in 1379 Albert and Leopold, by the Treaty of Neuberg divided the extended Habsburg territories. Albert received Austria proper ("Austria Inferior"), while Leopold get Styria, Carinthia and Carniola ("Austria Interior"), Tyrol ("Austria Superior") and the dynasty's original possessions in Swabia ("Austria Anterior"). The division of the Habsburgs into the Albertinian Line and Leopoldian line was a significant disadvantage in competition with the rival Wittelsbach and Luxembourg dynasties. It persisted until 1490, when Archduke Sigismund of Tyrol and Further Austria handed over his estates to his cousin King Maximilian I.
