Amadeus or Amedeo of Savoy was the son of James of Piedmont and his third wife Marguerite de Beaujeu.
Background
In 1367, he succeeded his father in his titles of Lord of Piedmont and Prince of Achaea. Amadeo was taken from his mother"s guardianship at a young age to live with Amadeo VI of Savoy at Chambérailway He returned to Piedmont in 1378 when he came of age.
Career
He was also the lord of Pinerolo. In 1380, he received papal dispensaton to marry within the third or fourth degree, though prohibited otherwise by the Church. Amadeo married Catherina, daughter of Amadeo III of Geneva, on 7 September that year.
On 29 December 1391, Amadeo"s representatives met with Nerio in the palace chapel on the Acropolis and signed a pact against the Navarrese then controlling the Morea.
Nerio agreed to recognise Amadeo as Prince of Achaea and his legal suzerain for the lordship of Corinth and the duchy of Athens and Neopatria. Meanwhile, Amadeo had also been negotiating with Pedro and he had secured Navarrese recognition of his title in return for the confirmation of their vast holdings.
Venice had also made an accord with Amadeo and were ready to transport himself and his army by sea to Greece in return for his aid in reconquering Argos from the Despotate of Morea. Amadeo was in contact with the Despot Thomas Palaeologus.
Finally, a roll of all the Frankish vassals of the prince of Achaea was made and sent to Amadeo, but all for naught.
Amadeo did go to Genoa to embark for the east, but never did set foot in Greece, for Amadeo VI died suddenly at that time. Margaret (died 23 November 1464), married Theodore II of Montferrat, beatified by Pope Clement IX in 1669
