Charles Emmanuel I (Italian: Carlo Emanuele di Savoia; 12 January 1562 – 26 July 1630), known as the Great, was the Duke of Savoy and ruler of the Savoyard states from 30 August 1580 until his death almost 50 years later in 1630, he was the longest-reigning Savoyard monarch at the time, only for his record to be surpassed by his great-grandson Victor Amadeus II. He was nicknamed Testa d'feu (lit. 'Hothead', in context "the Hot-Headed") for his rashness and military aggression.
Being ambitious and confident, Charles pursued a policy of expansion for his duchy, seeking to expand it into a kingdom.
