1580 CE
Lier, Bruges and the surrounding area sign the Union of Utrecht in February 1580.
The city of Groningen shifts from contra to pro under influence of the stadtholder for Friesland, George van Rennenberg, and also signs the treaty.
Overijssel and Drenthe sign also, as does Zutphen in April 1580; thus, Guelders (of which Zutphen is one of the quarters) now supports the Union completely.
The members now include the counties of Holland, Zeeland, and Flanders; the bishopric of Utrecht, the duchies of Guelders and Brabant; and the lordships of Groningen, Friesland, Drenthe, and Overijssel.
The seventeen provinces of the Netherlands are now effectively divided into a group of provinces loyal to the Spanish king, and another rebel group.
Flanders is almost entirely conquered by the Spanish troops, as is half of Brabant, so these two parts withdraw.
