Battle of Oosterweel
1567 battle of the Eighty Years' War

The Battle of Oosterweel took place on 13 March 1567 near the village of Oosterweel, near Antwerp, in present-day Belgium, and is traditionally seen as the beginning of the Eighty Years' War. A Spanish mercenary army surprised a band of rebels and killed or captured almost all of them.
Background
Beginning in 1566, Protestant mobs in the provincial states of the Netherlands began destroying Catholic art and images (the Beeldenstorm) to protest the taxes, restrictions on religion, and harsh rule of Philip II of Spain, sovereign of the Habsburg Netherlands. In March 1567, under the leadership of a young nobleman, Jean Marnix, rebels gathered and built a fortified compound at Oosterweel, approximately 1.6 kilometres (1 mi) from Antwerp.
Battle
Attempting to deal with the gathering of the rebels, Margaret of Parma, the Spanish governor of the Habsburg Netherlands, employed a mercenary army to confront the rebels. The army was provided in large part by the loyalist Count Egmont and led by Philip de Lannoy, Seigneur De Beauvoir, who served as the commander of the governor's bodyguards.
On 12 March, the Spanish mercenary army prepared for the battle in secret. The troop of eight hundred men was split into small groups and quietly placed for deployment. Helmets, bucklers, arquebuses, corselets, spears, standards and drums were distributed silently. Before daybreak on 13 March, the soldiers were advised that they would advance on the rebels with banners furled and no drumbeat.
This brief starts where responsible research should: with the source description of “Battle of Oosterweel” as 1567 battle of the Eighty Years' War. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the history & society register because the source frames it as 1567 battle of the Eighty Years' War. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Chronology, provenance and viewpoint should be read together before a broad social or political interpretation is accepted. The source revision retrieved here is dated Aug 21, 2026. The linked authority identifier is Q641757. Authority coordinates are 51.244, 4.385. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1567 and 1566.
Institutional narratives can privilege the records that survived while minimizing voices that were never formally collected. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
