The strip of coast from the mouth of the Scheldt to that of the Ems remained, however, in the hands of the free Frisians (q.v.), in alliance with whom against the Franks were the Saxons, who, pressing forward from the east, had occupied a portion of the districts known later as Gelderland, Overyssel and Drente.
Four duchies, Brabant, Gelderland, Limburg and Luxemburg; seven counties, Flanders, Artois, Hainault, Holland, Zeeland, Namur and Zutphen; the margraviate of Antwerp; and five lordships - Friesland, Mechlin, Utrecht, Overyssel, and Groningen with its dependent districts.
Towards the end of his career Gerhard Groot retired to his native town of Deventer, in the province of Overyssel and the diocese of Utrecht, and gathered around him a number of those who had been "converted" by his preaching or wished to place themselves under his spiritual guidance.
On the death of Frederick Henry William succeeded him, not only in the family honours and possessions, but in accordance with the terms of the act of survivance in all his official posts, as stadtholder of Holland, Zeeland, Utrecht, Gelderland, Overyssel and Groningen and captain-general and admiral-general of the Union.
He was succeeded in his dignities by his younger brother Frederick Henry (see Frederick Henry, prince of Orange), who was appointed stadholder of Holland, Zeeland, Utrecht, Overyssel and Gelderland, captain and adjutant-general of the Union and head of the Council of State.
