Philip did not govern in person but appointed Emmanuel Philibert, Duke of Savoy, as governor-general to lead the central government. In 1559 he appointed his half-sister Margaret of Parma as the first Regent, who governed in close co-operation with Dutch nobles like William, Prince of Orange, Philip de Montmorency, Count of Hoorn, and Lamoral, Count of Egmont. Philip introduced a number of councillors in the Council of State, foremost among these Antoine Perrenot de Granvelle, a Burgundian cardinal who gained considerable influence in the council, much to the chagrin of the Dutch council members.
