Albert III was born as the son of Albert II of Austria. Even though the latter had determined that the eldest son should the sole successor, after his death in 1358, Albert shared the rule with his three brothers Rudolf IV, Frederick III and Leopold III. In 1377, Albert went on a crusade agaist the paganLithuanians and Samogitians. After Rudolf's and Frederick's death without a heirs, Albert entered into the Treaty of Neuberg with to divide the Habsburg territories with Leopold III in 1379, in which he received Austria proper, while Leopold should rule Styria (duchy), Carinthia, Tyrol and Further Austria. His government was beneficial to the realm, as he supported the arts and science. Albert was an apt scholar himself, particularly a mathematician. He expanded the University of Vienna and attempted to refurbish Vienna.
In 1314 Albert's son, Frederick, was chosen German king in opposition to Louis IV., duke of Upper Bavaria, afterwards the emperor Louis IV., and Austria was weakened by the efforts of the Habsburgs to sustain Frederick in his contest with Louis, and also by the struggle carried on between another brother, Leopold, and the Swiss.
Austria and Spain were thus divided, and, in spite of the efforts of the archduke Charles in the Spanish Succession War, were never again united, for at the battle of Mohacs, on the 28th of August 1526, Suleiman the Mohacs Magnificent defeated and killed Louis, king of Bohemia and its g g results.
Austria proper was policy left to his eldest son Maximilian, Tirol to the archduke The of Ferdi- Ferdinand; and Styria with Carinthia and Carniola nand and to the archduke Charles.
