Eighty Years' War
The Eighty Years' War, or Dutch War of Independence, (1568–1648) began as a revolt against Philip II of Spain, the overlord of the Habsburg Netherlands. The war ended with the Treaty of Westphalia. This revolt partly succeeded with the secession of seven provinces which formed the Dutch Republic. Much later, the "rebel" provinces of Flanders and Brabant became modern-day Belgium (with the exception of North Brabant).
William of Orange, the leader of the revolt, explained his conflict with king Philip II to the Council of State in the following way: "I can not approve that monarchs desire to rule over the conscience of their subjects and take away from them their freedom of belief and religion."
- The Dutch States-General, for dramatic effect, decided to promulgate the ratification of the Peace of Münster (which was actually ratified by them on May 15, 1648) on the 80th anniversary of the execution of the Counts of Egmont and Horne, June 5, 1648.
