When his father died in 1343, Amadeus inherited the
County of Savoy. Since he was only nine years old, his father's will left two cousins as co-regents:
Amadeus III of Geneva and
Louis II of Vaud. The two agreed to a document limiting their power as regents. Neither could make any significant decision without the other, and the decisions of both were subject to review by the resident council of
nobles representing all
bailis in the county. Shortly after Amadeus took the county, his cousin
Joan of Savoy renewed her claim on the
County of Savoy, that she was descended from Amadeus's uncle
Edward, Count of Savoy, though her claim had previously been denied under Savoy's
Semi-Salic tradition. Though she died the following year, in her will she left the county to
Philip,
Duke of Orléans to spite her cousins. In 1345, he negotiated a similar settlement to the one Joan reached with Aymon, yielding the claim in exchange for 5000
livres annually. Amadeus was educated both physically and mentally. He enjoyed learning to fight and ride. His education included classic works such as
De Re Militari and more modern texts, including
De Regimine Principum. He also showed religious devotion, requesting a portable
altar and the right for his
chaplain to say
mass for him every morning wherever he may be. He took vows to fast more often than was healthy for him, and then asked
Pope Clement VI to release him from these vows. The
pope agreed, asking him instead to feed twelve of the poor weekly. When the young Angevin queen
Joanna I of Naples took the throne, several in northern
Italy sought to take advantage of her inexperience and seize her lands there.
John II, Marquess of Montferrat led the first attacks, while
James of Piedmont, a cousin and vassal of Amadeus, backed the queen. After her first army was defeated in 1345, the attackers moved next into the territory ruled by James. In 1347, James asked Amadeus for help, and Amadeus sent an army. That army swept the attackers back through July of that year, with Amadeus joining the fighting in the last few weeks. John then recruited the help of
Humbert II, Dauphin of Viennois, an old enemy of the Savoyards, and
Thomas II, Marquess of Saluzzo. Together, they conquered the Angevin lands.
Pope Clement VI spent 1348 negotiating a
truce to end the fighting, which none of the combatants were satisfied with. From 1348 through 1351, the
Black Death ravaged the lands of
Savoy, halving the population in some
villages. In 1348, many of the
peasants thought that it was caused by
Jews poisoning wells and fountains. Though the
castellans in some places tried to protect them, quite a few were
killed. In
Chambéry, the Jews were locked in the castle for their protection, but a mob broke in and killed several. Court officers were then pressured into finding the remainder guilty of
poisoning, executing eleven and
charging the remainder a fine of 160
florins per month for the next six years. In 1349, Amadeus agreed to a treaty between himself, Amadeus of Geneva, James of Piedmont, and the
House of Visconti, rulers of the
Lordship of Milan, for mutual defence and assistance. This treaty included provisions for Lord
Galeazzo II Visconti to marry
Bianca of Savoy, sister of the count. To honour the
marriage in 1350, Amadeus created the
Order of the Black Swan. In 1349, Humbert II de La Tour du Pin, Dauphin of Viennois, the last
Dauphin of Viennois, surrendered his title and principality to the future
King Charles V of France. At the time, the new
Dauphin was the grandson of the current King
Philip VI of France and son of his
heir apparent, the later King
John II of France. Humbert II
retired into a
Dominican monastery. ==Count of Savoy==
