The following are the territorial changes that occurred in Prussia:

Austria acquired Venice and much of northern Italy, while Prussia obtained lesser German provinces in the west, Swedish Pomerania, and 40% of the Kingdom of Saxony. Parts of Poland were taken by Russia.

The territorial adjustments occurred as a result of Austria's fear of Britain's growing might. Prussia became a larger menace to Austria than France. Prussia was seen by Austria as an ally in the fight against the Ottomans.
