What about this TL?
1549 – The Pragmatic Sanction of 1549, promulgated by Charles V, Holy Roman Emperor, reorganizing the Seventeen Provinces.
1555 – Charles V abdicates in favour of his son, Philip II of Spain. Philip inherits the Seventeen Provinces. Philip and William, Prince of Orange (Charles personal favorite) become close friends (living in the Netherlands the first part of his reign).
1559 - Philip appoints William, Prince of Orange as the stadtholder of the provinces Holland, Zeeland and Utrecht. Margaret of Parma (Philips half-sister) is appointed governor of the Netherlands. William and Philip, both being very religious, agree that the inquisition policy isn’t very biblical.
1561 – William gains the stadtholdership of Franche-Comté and maries Anna of Saxony the same year.
1564 – Granvelle, prime minister to Margaret of Parma retires on the advice of his royal master. Without his policy of repression, the protestant minority enjoys more and more religious freedom.
1565 – William, the Confederacy of Noblemen and Margaret of Parma formally establish an end to the persecution of Protestants.
1566 - At the end of a pilgrimage from Hondschoote to Steenvoorde, the chapel of the Sint-Laurensklooster was defaced by a crowd who invaded the building. William and even protestant noblemen condemn the destructions. The (growing) protestant minority in the Netherlands fears new persecutions again and quickly take a stance against the violence. Iconoclastic Fury(Beeldenstorm) in the Low Countries is avoided.
1567 – Margret establishes the Council of religious freedom, dedicated to peacefully resolving religious issues.
1569 – Margret assassinated by a Catholic Frenchman, calling her pest on the whole of Christianity and the enemy of the human race. Philip, enraged, vows to bring an end to Catholic/Protestant hatred and finds an ally in William.
