Turin was declared capital city of Italian chocolate right after the Cateau-Cambrésis peace treaty was signed in 1559: Duke Emmanuel Philibert of Savoy, who had served as governor of the Habsburg Netherlands until that year, returned from Spain with some cocoa seeds – one of the American novelties Hernán Cortés had introduced in Europe after conquering Mexico.
