What did the Treaty of Hubertusburg decide about Silesia?

The Treaty of Hubertusburg, signed in 1763, formally concluded the Seven Years’ War between Austria and Prussia. Regarding the province of Silesia, the treaty acknowledged the status quo ante, confirming that Prussia retained possession of the territory.123

Although Maria Theresa had tenaciously sought to recover the province, her efforts remained unsuccessful. The agreement effectively solidified Prussia's stature as a major European power and ended the long-standing contest over the region that had persisted through the Silesian Wars.312
