of Friesland the Lordship of Overijssel the Duchy of Guelders (except its upper quarter) and the County of Zutphen the Prince-Bishopric, later Lordship of Utrecht the County of Holland the County of Zeeland The southern provinces, Flanders, Brabant, Namur, Hainaut, Luxembourg and the others, were restored to Spanish rule due to the military and political talent of the Duke of Parma, especially at the Siege of Antwerp (1584–1585). Hence, these provinces became known as the Spanish Netherlands or Southern Netherlands. The County of Drenthe, surrounded by the other northern provinces, became de facto part of the Seven United Provinces, but had no voting rights in the Union of Utrecht and was therefore not considered a province. The northern Seven United Provinces kept parts of Limburg, Brabant, and Flanders during the Eighty Years' War (see Generality Lands), which ended with the Treaty of Westphalia in 1648. Artois and parts of Flanders and Hainaut (French Flanders and French Hainaut) were ceded to France in the course of the 17th and 18th centuries. Economy By the mid-16th century, the Margraviate of Antwerp (Duchy of Brabant) had become the economic, political, and cultural centre of the Netherlands after its capital had shifted from the nearby Lordship of Mechelen to the city of Brussels. Bruges (County of Flanders) had already lost its prominent position as the economic powerhouse of northern Europe, while Holland was gradually gaining importance in the 15th and 16th centuries. However, after the revolt of the seven northern provinces (1568), the Sack of Antwerp (1576), the Fall of Antwerp (1584–1585), and the resulting closure of the Scheldt river to navigation, a large number of people from the southern provinces emigrated north to the new republic. The centre of prosperity moved from cities in the south such as Bruges, Antwerp, Ghent, and Brussels to cities in the north, mostly in Holland, including Amsterdam, The Hague, and Rotterdam. Netherlands To distinguish between the older and larger Low Countries of the Netherlands from the current country of the Netherlands, Dutch speakers usually drop the plural for the latter. They speak of Nederland in the singular for the current country and of de Nederlanden in the plural for the integral domains of Charles V. In other languages, this has not been adopted, though the larger area is sometimes known as the Low Countries in English. The fact that the term Netherlands has such different historical meanings
