| General Description : | The Union of Utrecht (Dutch: Unie van Utrecht) was a treaty signed on 23 January 1579 in Utrecht, the Netherlands, unifying the northern provinces of the Netherlands, until then under the control of Habsburg Spain. The Union of Utrecht is regarded as the foundation of the Republic of the Seven United Provinces, which was not recognized by the Spanish Empire until the Twelve Years' Truce in 1609. The treaty was signed on 23 January by Holland, Zeeland, Utrecht (but not all of Utrecht) and the province (but not the city) of Groningen. The treaty was a reaction of the Protestant provinces to the 1579 Union of Arras (Dutch: Unie van Atrecht), in which the southern provinces declared their support for Roman Catholic Spain. |
