Amadeus III, Count of Savoy

Who was Amadeus III, Count of Savoy?

Amadeus III of Savoy was Count of Savoy and Maurienne from 1103 until his death. He was also known as the Crusader.

He was born in Carignano, Piedmont, the son of Humbert II of Savoy and Gisela of Burgundy, the daughter of William I of Burgundy. He succeeded as count of Savoy upon the death of his father. Amadeus had a tendency to exaggerate his titles, and also claimed to be Duke of Lombardy, Duke of Burgundy, Duke of Chablais, and vicar of the Holy Roman Empire, the latter of which had been given to his father by Henry IV, Holy Roman Emperor.

He helped restore the Abbey of St. Maurice of Agaune, in which the former kings of Burgundy had been crowned, and of which he himself was abbot until 1147. He also founded the Abbey of St. Sulpicius in Bugey, Tamié Abbey in the Bauges, and Hautecombe Abbey on the Lac du Bourget.

In 1128, Amadeus extended his realm, known as the "Old Chablais", by adding to it the region extending from the Arve to the Dranse d'Abondance, which came to be called the "New Chablais" with its capital at Saint-Maurice. Despite his marriage to Mahaut, he still fought against his brother-in-law Guy, who was killed at the Battle of Montmeillan. Following this, King Louis VI of France, married to Amadeus' sister Adélaide de Maurienne, attempted to confiscate Savoy. Amadeus was saved by the intercession of Peter the Hermit, and by his promise to participate in Louis' planned crusade.
