Union of Utrecht
1579 CE – 1581 CE · 38,590 km²

The Union of Utrecht (Dutch: Unie van Utrecht) was an alliance based on an agreement concluded on 23 January 1579 between a number of Dutch provinces and cities, to reach a joint commitment against the king, Philip II of Spain. By joining forces, they hoped to force him to stop his harsh administrative measures. In addition, some important political matters were regulated in areas such as defence, taxation and religion, which is why the treaty in question is also seen as a first version or precursor of a later constitution.

Government, Society and Religion
The Union of Utrecht allowed complete personal freedom of religion and was thus one of the first unlimited edicts of religious toleration. An additional declaration allowed provinces and cities that wished to remain Roman Catholic to join the union.
