The lake country north of the Rhin marshes was the land of the Zamzizi, a Slav people with their chief castle on an island in the Ruppiner See.
After the Wendish crusade of 1147 it came under German overlordship and settlers followed in the later 12th century. The counts of Arnstein, Ascanian kin from the eastern Harz, take it only about 1214: Gebhard of Arnstein is the first attested lord, builds the castle of Ruppin (the Planeburg) after 1220 and founds Neuruppin before 1238 (town law 1256). On 1 January 1200 the Arnsteins are not yet here, and who holds the Ruppin land is not pinned.

What the year holds
What happened next, if nothing in play changes it. Each event carries what it depends on and what would stop it.
- about 1214 (not yet)Count Gebhard of Arnstein becomes lord of Ruppin.Depends on: The margraves' grant or acceptance; the Arnsteins' expansion. Stopped by: Another holder established first.
Places of note
- Slav castle in the Ruppiner See: Centre of the Zamzizi.
Where the sources disagree
- The Rhineland map's Arnstein record covers the Arnstein family on the eastern Harz; its Ruppin branch belongs to about 1214 and later, not to 1 January 1200.
Evidence: No holder is recorded before Gebhard of Arnstein (about 1214).
On the map: Outline from the later lordship of Ruppin; in 1200 a frontier land.
