In 1624 arrived eighteen families of Dutch Walloons, the first actual permanent settlers, as distinguished from traders.
Other Protestant bodies are the Walloons, who, though possessing an independent church government, are attached to the Low-Dutch Reformed Church; the Lutherans, divided into the main body of Evangelical Lutherans and a smaller division calling themselves the Re-established or Old Lutherans (Herstelde Lutherschen) who separated in 1791 in order to keep more strictly to the Augsburg confession; the Mennonites founded by Menno Simons of Friesland, about the beginning of the 16th century; the Baptists, whose only central authority is the General Baptist Society founded at Amsterdam in 1811; the Evangelical Brotherhood of Hernhutters or Moravians, who have churches and schools at Zeist and Haarlem; and a Catholic Apostolic Church (1867) at the Hague.
On the north-west frontier reside about 10,000 Walloons, who speak French or Walloon as their native tongue.
During the Crusades, and in the middle ages, the term Belgicae principes is of frequent occurrence, and when in 1790 the Walloons rose against Austria during what was called the Brabant revolution, their leaders proposed to give the country the name of Belgique.
Farnese first won by promises and blandishments the confidence of the Walloons, always jealous of the predominance of the " Flemish " provinces, and then proceeded to make himself master of Brabant and Flanders by force of arms. In succession Ypres, Mechlin, Ghent, Brussels, and finally Antwerp (17th of August 1585) fell into his hands.
