The Treaty of Trieste was a 1453 treaty between the Duchy of Austria and the Kingdom of Italy, ending the Austro-Italian War, which resulted in an Austrian defeat.
The original terms were drafted following the Battle of Trieste and the seizure of Istria and Carniola by the Italian forces.
In 1454, following the Battle of Laibach/Lubiana, the terms were revised so as to offer the nobles of South Tyrol, Trent, Carniola, and Istria to choose between Austria and Italy.
