While European powers are involve in War of the Spanish Succession, emperor Leopold I. Habsburg slowly realises how problematic an unresolved matter of succession can be. As soon as Charles VI. rose to power, the matter of solving the potential dynastic disputes of the Habsburg dynasty became a priority. Queen/regent Eleonore and Croatian parliament ably succeeded to pass a Croatian Pragmatic Sanction in 1712. which helped the Habsburg dynasty in making the Pragmatic Sanction in year 1713. The Pragmatic Sanction was accepted by all the countries in The Habsburg Monarchy, and in Europe. Pragmatic Sanction ensured Maria Theresa inherited The Habsburg Monarchy after her father, Charles VI. passed away. Driven by the ambition of territorial expansion of Prussia, Fredrick II. of Hohenzollern-Brandenburg dynasty, later known as Fredrick II. The Great, started the First Silesian War in 1740. The following year, Europe was in another dynastic war, this time War of the Austrian Succession in which husbands of the Habsburg princesses, Maria Josepha and Maria Amelia, had intentions of obtaining the crown of the Habsburg Monarchy for Charles Albert (husband of Maria Amelia). During the war, husband of Maria Josepha, Augustus III. changed several times the side he was on, and Charles Albert became an emperor Charles VII. of The Holly Roman Empire (1742.-1745.). With the ending of the Second Silesian War in 1745. Fredrick II. The Great secured Silesia for himself and thus ended the second part of the Prussian involvement in War of the Austrian Succession. After eight years of War of the Austrian Succession, the treaty of Aix-la-Chapelle was singed thus ensuring Maria Theresa’s right in inheriting The Habsburg Monarchy and her husbands, Francis Stephen, title of the emperor of The Holly Roman Empire.
