From the 16th till the 18th century Friesland was divided into four
political entities. Three rural quarters: Westergo [Westergoa]
in the west; Oostergo [Eastergoa] in the northeast;
and Zevenwouden [Sawnwâlden] in the southeast.
These were divided into so called grietenijen, who consisted of
5 to 31 villages.
The fourth were the eleven cities.
Around 1500 the Saxon Stellingwerven was incorporated
into Zevenwouden.
The flag of Westergo was blue with a white diagonal stripe from the
lower hoist to the upper fly.

Stellingwerven
The Stellingwerven consist of the modern municipalities Weststellingwerf
(with the town Wolvega) and Ooststellingwerf [Eaststellingwerf] (with the
towns Oosterwolde and Appelscha).
The arms of the municipalities of Weststellingwerf and Ooststellingwerf
both show on silver a red griffin with a red disc with a star under it.
The two arms are different in details, but maybe they are variants of the
old arms of Stellingwerf?
Both municipalities use red-white flags with the griffin. (See Shipmate's
flagchart).
Four of the six Dutch Frisian islands belong to the province of Friesland.
These are: Vlieland, Terschelling
(both ceded to Holland in 1615, and returned
to Friesland in 1942), Ameland and Schiermonnikoog.
Texel (or Tessel) is part of the province
of Noord-Holland, Rottumeroog of the province of Groningen.
Nowadays each island is a separate municipality, except the since-1969
uninhabited Rottumeroog which belongs to the municipality of Eemsmond.
