James of Savoy-Achaia
James of Savoy-Achaia (1315–1367) was born at Pinerolo, the eldest son of Philip I of Piedmont. Succeeding as Lord of Piedmont in 1334, he kept the title Prince of Achaea though Naples had seized the principality in 1307.
In 1347 he and his cousin Amadeus VI of Savoy retook Chieri from John II of Montferrat and other towns. Later warring with Amadeus, he was captured at Pinerolo and lost his lands, restored by treaty in 1362. He died there in 1367.
