Following his victory in the Schmalkaldic War in 1547, Ferdinand I extracted recognition from the Bohemian Diet that the royal succession would be hereditary.
[4] It was only following the Battle of White Mountain (1620), a victory over Bohemian rebels during the Thirty Years' War, that Ferdinand II promulgated a Renewed Land Ordinance [de] (1627/1628) that definitively established hereditary succession.
In his will and testament of 1621, Ferdinand II tried to establish the principle of primogeniture to ensure that the Erblande would not be divided again as in 1564.
Following the Battle of Mohács (1687), in which Leopold I reconquered almost all of Hungary from the Ottoman Turks, the emperor held a diet in Pressburg to establish hereditary succession in the Hungarian kingdom.
[5] Although the term Erblande was often extended to include Bohemia (which lay within the Holy Roman Empire) after 1627, it was never used to describe Hungary, even after 1687.
