帝国アハト刑
From 1648 onwards, inheritance of the Estate was limited to one family; a territory inherited by a different family ceased to be an Estate unless the Emperor explicitly allowed otherwise. Finally, a territory could cease to be an imperial Estate by being subjected to the Imperial ban (the most notable example involved the Elector Palatine Frederick V, who was banned in 1621 for his participation in the Bohemian Revolt).
