Giulio Mazarini was born, either in Rome or in Pescina, in 1602, the son of a Sicilian subject of Philip IV of Spain. In 1639, he became a naturalized Frenchman, changed his name to Jules Mazarin and rose eventually to occupy the position of prime minister of France. Naturally, he was regarded by Louis XIII and Louis XIV as a French subject. However, in 1651 the Paris parliament identified his as a foreigner despite his naturalized status and pleaded with the Monarch to pass a law excluding from the royal councils "tous Estrangers, mesmes les naturalisez". Meanwhile, Philip IV was more than a little put out by the fact that the son of one of his subjects was forging strong links with France at a time when France and Spain were at war.
