He thereforemoved the capital to Turin, 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. His son, Charles Emmanuel I, extended the duchy to the detriment of the lordships of Monferrato and the territory of Saluzzo, previously ceded to France, in 1601 under the Treaty of Lyon. Unfortunately, the wars of Charles Emmanuel ended mostly in defeats. Nevertheless, he is remembered as "Charles the Great", since he was a versatile and cultured man, a poet and a skillful reformer. He was able to manage the Duchy at a time of severe crisis vis-a-vis the European powers and found support from the Habsburgs. The policy of Charles Emmanuel was in fact based more on actions of international warfare, such as the possessions of the Marquis of Saluzzo, and the wars of succession in the duchies of Mantua and Monferrato. Generally, Savoy sided with Spain, but on occasion allied with France (as, for example, the Treaty of Susa required). 17th century During the seventeenth century, the influence of the court of Versailles put pressure on Savoy. Due to the proximity of the Duchy of Milan, troops were stationed in France, and the disposal of Pinerolo (one of the most important strongholds of Savoy), were situated close to Turin. The court, which had been under Spanish influence with Charles Emmanuel I, became oriented towards France under his three successors. Vittorio Amedeo I (in office 1630–1637) had married Madame Royale, Maria Christina of Bourbon-France in 1619. Cristina held the real power in Savoy during the short period of the child-duke Francis Hyacinth (reigned 1637–1638) and during the minority (1638-1648) of Charles Emmanuel II. During the Thirty Years' War, Savoy was one of the states of the Holy Roman Empire that largely sided with France and against both the Emperor and Spain. Savoyard troops participated on the side of the French in the Savoyard-Genoese War, the War of the Mantuan Succession, the Tornavento campaign and, in part, in the
