Emmanuel Philibert realized that Savoy could no longer trust France. So he moved the capital to Turin, and which he protected with a complex system of fortifications known as the Cittadella. (Remnants of the Citadalla can still can be seen, although it was largely destroyed by the subsequent expansion of the city.) From his military experience in Flanders, Emmanuel Philibert learned how to run an army, having won the famous Battle of St. Quentin. He was the first Duke of Savoy to establish a stable military apparatus that was not composed of mercenaries but rather by specially trained Savoyan soldiers.
