Conquest of Podolia by Casimir the Great
Casimir the Great, the last king of the Piast dynasty, made a strategic conquest of Podolia in the 1360s. The military campaign, culminating in the capture of Kamienets-Podolsky in 1362, significantly strengthened Poland's position in the east. The incorporation of this region ensured control over important trade routes and created a barrier against Tatar invasions.
