The duke's own share of Greater Poland on 1 January 1200: Kalisz, where he lives and where he founded the collegiate church of St Paul; Gniezno, the archbishop's city, with the heartland castles of Giecz, Ląd, Kłecko and Lednica; the Pałuki with Nakło on the Noteć; and the march castles on the Noteć, the Warta and the Obra, each held for him by a castellan whose name for 1199-1200 is lost.

Overlord
None (claims the seniorate)
What it holds
- Kalisz castle and its land: taken from the senior province in 1181; given to Mieszko the Younger 1191-93 and to Odon 1193-94; his own since 1194
- Gniezno castle and district (the archbishop's city and see)
- Giecz and Ląd castles with their districts; Kłecko; Lednica
- Nakło on the Noteć with the southern Krajna and the Pałuki (Kcynia, Szubin, Gąsawa)
- The march castles of Santok, Drzeń, Wieleń, Czarnków and Ujście on the Noteć and Warta, and Międzyrzecz, Zbąszyń and Wschowa on the Obra march (see the march records)
- The mint, the market and river tolls, the ducal law over the peasants
- Kraków and the senior province, by the usual reckoning (krakow record)
How it was acquired
See the realm record. Kalisz and Gniezno were taken from the senior province in 1181 with Pomeranian help.
Allies and rivals
Allies: his grandsons the Pomeranian dukes; Jaromar I of Rügen; the Silesian princes Mieszko Tanglefoot and Jarosław of Opole (at Mozgawa, 1195). Rivals: the Kraków lords round Helen of Znojmo, Bishop Pełka and the palatine Mikołaj; Leszek the White.
How things stand that morning
He holds these districts directly through his castellans. Whether the march castles of the Noteć and the Obra answered to him or to his son in Poznań is not pinned; as duke and senior he is overlord of both shares.
Wealth
The Kalisz and Gniezno plains (grain, cattle), the market dues of Gniezno and Kalisz, the Noteć and Warta tolls, the mint.
Military
His retinue and the knights of the castle districts; the castles listed. Beaten at Mozgawa (1195).
Threats
- Age
- The Kraków lords
- Family strife over Odon's land
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.
- 13 March 1202Dies at Kalisz; buried in St Paul's there. His share passes to Władysław Spindleshanks.Depends on: Natural course. Stopped by: Play that changes his circumstances.
Places of note
- Kalisz-Zawodzie: castle and St Paul's: Residence and foundation.
- Gniezno castle: The archbishop's see and the duke's castle.
- Giecz: Old Piast castle, seat of a castellan.
- Ląd: Castle on the Warta and Cistercian abbey.
Where the sources disagree
Evidence: His residence at Kalisz, the recovery of Gniezno and Kalisz in 1181 and his death and burial at Kalisz are well reported. Which castle districts he kept and which his son governed after 1194 is not pinned beyond Odon's land south of the Obra.
On the map: The split between father and son is drawn from the usual account (the son has Odon's land and Poznań); the marches are given to the father as overlord.

- Chronicle of the Poles, by Master Vincent (Wincenty Kadłubek), Wincenty Kadłubek (about 1190 to 1208). Book 4 is a contemporary's account of the fight for the senior throne of Kraków. Read online
- The annals of the Kraków chapter and the other Polish annals (kept from the 11th century; the Kraków chapter annals continued to 1266). Short dated entries that fix the chronology Kadłubek blurs: the deaths of dukes and bishops, Mieszko the Old's captures of Kraków, Prussian raids on Masovia, church consecrations. Read online
