Thomas III of Piedmont
Thomas III (c. 1246–1282), lord of Piedmont, was the eldest son of Thomas II of Savoy. Succeeding his father in 1259, he claimed Savoy when his cousin Boniface died in 1263, but was twice bypassed for his uncles. In 1274 he married Guia of Burgundy; their son Philip founded the Savoy-Achaea line.
In 1280 he captured William VII of Montferrat and forced him to surrender Turin. Mortally wounded in a feud, he died in 1282.
