Thomas, Count of Savoy  Thomas Ι ("Tommaso I"; 1178 – 1 March 1233) was Count of Savoy from 1189 to 1233. He is sometimes numbered "Thomas I" to distinguish him from his son of the same name, who governed Savoy but was not count. Thomas was born in Aiguebelle, the son of Humbert III of Savoy and Beatrice of Viennois. His birth was seen as miraculous; his monkish father had despaired of having a male heir after three wives. Count Humbert sought counsel from St. Anthelm, who blessed Humbert three times, and it was seen as a prophecy come true when Thomas was born shortly before Anthelm himself died on 26 June 1178. He was named in honour of Saint Thomas Becket. Thomas was still a minor when his father died on 4 March 1189, and a council of regency was established, composed of his mother Beatrice, his father's cousin Boniface I of Montferrat, and the Bishop of Saint-Jean-de-Maurienne. He had reached his majority by August 1191. Thomas possessed the martial abilities, energy, and brilliance that his father lacked, and Savoy enjoyed a golden age under his leadership. Despite his youth he began the push northwest into new territories. In the same year he granted Aosta Valley the "Charte des Franchises", recognising the right to administrative and political autonomy. This right was maintained until the eve of the French Revolution. Later he conquered Vaud, Bugey, and Carignano. He supported the Hohenstaufens, and was known as "Thomas the Ghibelline" because of his career as Imperial Vicar of Lombardy. Thomas worked throughout his career to expand the control and influence of the County of Savoy. One of the key tools that he used was his large number of children, whom he worked to get into positions of influence in neighboring regions. In part, this was done by getting many of his sons into episcopal offices in surrounding territories, in a time when bishops had temporal as well as spiritual authority. In addition to Guglielmo and Bonifacio, who made their careers in the clergy, their brother Thomas started out as a canon at Lausanne and became prévôt of Valence by 1226. Pietro was also a canon at Lausanne and served as acting bishop there until he was replaced in 1231.
