The Counts of Savoy were a noble family that ruled the region of Savoy in the western Alps, which is now part of France and Italy. Their lineage began in the 11th century, and they played a significant role in the political landscape of medieval Europe. The counts expanded their territory through strategic marriages and military conquests. Over time, the Counts of Savoy became influential in the formation of the Duchy of Savoy, which was established in the 15th century. This duchy later evolved into the Kingdom of Sardinia, contributing to the unification of Italy in the 19th century. The family's legacy continues to be recognized in the region today.
