From 1756 to 1763, Central Europe was scarred by the Seven Years' War. A coalition led by the Habsburgs of Austria with Saxony as an ally fought against Prussia. At the beginning of 1763, peace negotiations took place, including at Hubertusburg Castle, which had previously been sacked by the Prussians. One of the leading mediators for Saxony was Baron Thomas von Fritsch. On February 15, the Hubertusburg Peace was concluded, ending the Seven Years' War.
