Primary sources for Holland
Chronicles, registers, sagas and inscriptions written in or near 1200 that cover this entry. Each has its own page with editions, translations and where to read it.
- Annals of Egmond (12th century to about 1205). The house annals of Egmond, the counts of Holland's abbey, and the main native source for Holland around 1200. Read online
- Chronicle of the abbots of Wittewierum (Bloemhof), Emo of Wittewierum (from 1219 to 1237, continued by Menko to 1273). The chronicle opens only in 1204 with the founding of Emo's Premonstratensian house in the Groningen Ommelanden, so it has nothing for 1200 itself. Read online
