Eighty years of revolt forged the Dutch Republic
From about 1566–1568 to 1648, rebels in the Habsburg Netherlands fought Spanish rule over religion, taxes, centralization, and privilege. Mutinies, William of Orange's leadership, and the 1581 Act of Abjuration carved a Calvinist north that Spain finally recognized at Münster.
Philip II's armies first recovered most rebel territory, but mutinies among unpaid Spanish troops triggered a general uprising. Under the exiled William the Silent, Catholic and Protestant provinces tried to bury their differences through the Pacification of Ghent, yet that broad front collapsed. The Duke of Parma, governor for Spain, kept winning ground, while the northern Union of Utrecht renounced Philip in the Act of Abjuration of 1581 and formed a Calvinist-led republic in 1588. France and England recognised it in 1596, and Dutch raids on Portuguese outposts seeded a colonial empire.
Money ran short on both sides, and a ceasefire signed at Antwerp on 9 April 1609 opened the Twelve Years' Truce. It was a triumph for Holland's advocate Johan van Oldenbarnevelt, since Spain effectively acknowledged the republic, and a humiliation in Madrid, which also had to swallow the closure of the Scheldt and Dutch trading in Iberian colonial waters.
Peace abroad brought turmoil at home. A theological dispute between Remonstrants and their Calvinist opponents turned into street riots, with Oldenbarnevelt backing the first camp and the stadtholder Maurice of Nassau the second. The Synod of Dort condemned the Remonstrants as heretics; Oldenbarnevelt was executed and the jurist Hugo Grotius sentenced to life imprisonment. When the truce expired in 1621 the war resumed inside the wider Thirty Years' War.
Talks began at Münster in January 1646, with eight Dutch delegates because no province trusted another to speak for it. The 79-article treaty was fixed on 30 January 1648 and sworn on 15 May, even though Zeeland refused to sign. Spain kept the southern provinces and conceded the rest. The republic proclaimed the peace on 5 June, eighty years to the day after the counts of Egmont and Horne were executed.
