[1] Under the reign of Thomas, Saluzzo blossomed, achieving a greatness which had eluded his ancestors.

He crafted a state the borders of which remained unchanged for over two centuries.

He was often at odds with Asti and he was a prime enemy of Charles of Anjou and his Italian pretensions.

During his tenure, he made Saluzzo a free city, giving it a podestà to govern in his name.

He defended his castles and roccaforti (strongholds) vigorously and built many new ones in the cities.
