The Duchy of Greater Poland was a district principality that encompassed much of the historical region of Greater Poland, with a territory roughly corresponding to the present-day Greater Poland Voivodeship in west-central Poland. It emerged in the 12th century following the 1138 testament of Bolesław III Wrymouth, which divided the previously unified Kingdom of Poland into several hereditary duchies, initiating a period of feudal fragmentation. Although nominally part of the Polish realm, the duchy functioned as a semi-autonomous Piast principality, governed independently by its own dukes.

👉 Duchy of Greater Poland in the context of Duchy of Poznań
The Duchy of Poznań (Polish: Księstwo poznańskie; Latin: Ducatus Posnaniensis) was a feudal district duchy in Greater Poland, with its territorial and administrative core in the Poznań Land — the region surrounding the city of Poznań. Its capital was Poznań. The duchy was established in 1177, following the partition of the Duchy of Greater Poland after a rebellion against Mieszko III. Duke Odon of the Piast dynasty became its first ruler.
Initially, Poznań remained a fiefdom within the broader Duchy of Poland — a term commonly applied to the fragmented realm, which some sources continue to refer to as the Kingdom of Poland — until 1227, when Poznań gained independence as a duchy. It existed in this form until 1279, when it was united with the duchies of Gniezno and Kalisz under the rule of Przemysł II, forming a reconstituted Duchy of Greater Poland.

Duchy of Greater Poland in the context of Przemysł I of Greater Poland
Przemysł I (4 June 1221 – 4 June 1257), a member of the Piast dynasty, was Duke of Greater Poland from 1239 until his death, from 1241 with his brother Bolesław the Pious as co-ruler. He was able to re-acquire large parts of Greater Poland, ruling as Duke of Poznań and Gniezno from 1247 and, upon several inheritance conflicts with his brother, as Duke of Poznań and Kalisz from 1249, sole Duke of Greater Poland from 1250, and Duke of Poznań from 1253 until his death.
The numeral primus ("The First") was given to him in the almost contemporary Wielkopolska Chronicle.

Initially, Kalisz remained a fiefdom within the broader Duchy of Poland — a term commonly applied to the fragmented realm, which some sources continue to refer to as the Kingdom of Poland — until 1227, when Kalisz gained independence as a duchy. It existed in this form until 1279, when it was united with the duchies of Gniezno and Poznań under the rule of Przemysł II, forming a reconstituted Duchy of Greater Poland.

Between 1238 and 1239 he also served as regent of Sandomierz and Opole–Racibórz. He was the son of Henry the Bearded and a member of the Silesian Piast dynasty.
