Which treaties confirmed Prussia’s control of Silesia?

Several treaties throughout the 18th century confirmed Prussia’s control of Silesia following its conquest by Frederick II:

• Treaty of Breslau (1742): Following the First Silesian War, Maria Theresa ceded most of Silesia to Prussia, retaining only the districts of Troppau, Teschen, and Jägerndorf.1
• Treaty of Dresden (1745): This agreement concluded the Second Silesian War and reaffirmed Prussia's possession of the territory.1
• Treaty of Aix-la-Chapelle (1748): While Prussia was not a party to this treaty, the other European powers guaranteed Prussia’s conquest of Silesia, further solidifying its control.2
• Treaty of Hubertusburg (1763): Ending the Third Silesian War (part of the Seven Years’ War), this treaty restored the status quo ante, with Silesia and Glatz formally remaining under Prussian control.13
