The Satisfactie van Haarlem was one of many treaties in the city of Veere in 1577 where Willem the Silent ensured the loyalty of the cities under his rule.
Godfried van Mierlo set his seal to the "Satisfactie van Haarlem" wherein he promised that the Catholics of the city of Haarlem would swear allegiance to Willem the Silent rather than Philip II of Spain, on the condition that the Catholics would keep the same rights as Protestants. A year later this treaty was violated with the Haarlemse Noon on May 29, 1578.
