On the basis of agreements concluded with his powerful brother Emperor Charles V, Ferdinand I was assigned the patrimonial lands of the Habsburgs in Central Europe, thus founding the Austrian line of the family. His administrative reforms had an enduring influence. Ferdinand took radical action to deal with his adversaries, executing members of the Estates at the Wiener Neustädter Blutgericht. In his will he divided the Habsburg patrimonial lands among his three sons.
