The swearing of the oath of ratification of the treaty of Münster in 1648 (1648) by Gerard ter Borch
In 1581, several years after the seven northern Netherlands provinces of Holland, Zeeland, Utrecht, Gelderland, Overijssel, Friesland, and Groningen formed the Union of Utrecht, they declared independence from Spain. Decades of conflict followed. When the Peace of Westphalia ending the Thirty Years' War was reached in 1648, it included the Peace of Münster, a treaty between Spain and the United Netherlands that ended the Dutch Revolt. Where can an original copy of the Peace of Münster be found? Discuss...
