1579 – The Union of Arras is signed.

The Union of Arras (Dutch: Unie van Atrecht, Spanish: Unión de Arrás) was an accord signed on 6 January 1579 in Arras (Atrecht), under which the southern states of the Netherlands, today in Wallonia and the Nord-Pas-de-Calais (and Picardy) régions in France and Belgium, expressed their loyalty to the Spanish king Philip II and recognized his Governor-General, Don Juan of Austria. It is to be distinguished from the Union of Utrecht, signed later in the same month.

These were the conditions:

There should be no more garrisons of foreign troops;

The Council of State should be organized like that of the time of Charles V;

Two thirds of the council members should be installed by all member states consenting.

All privileges that were in force before the Dutch Revolt should be reinstated.

Catholicism was the only religion. Any other religion (i.e. Calvinism) should be abolished.

The regions that signed it were:

County of Hainaut

County of Artois

Lille, Douai and Orchies (Lilloise Flanders)

Bishopric of Cambrai

The regions that favored the Union, but did not sign it, were

County of Namur,

County of Luxembourg,

Duchy of Limburg.

Alexander Farnese, the Duke of Parma, used these counties as a base to start his conquest of the separatist parts (members of the Union of Utrecht).
