After signing the
Treaty of Lyon in 1601 with
Henry IV of France, Charles Emmanuel I aimed to improve his relations with his brother-in-law
Philip III of Spain. In order to complete the education of his eldest sons, he sent the boys to the Spanish court. Philip Emmanuel, along with his brothers Victor Amadeus and Emmanuel Philibert, arrived in
Valladolid, where the court was established at the time, at the end of August 1603. In October, their uncle Philip III gave each of them their own house. After arriving in Spain,
Tomás Fernández de Medrano began his role as their Secretary of State and War in 1603. == Death ==
