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.Józef Dobosz, Kazimierz II Sprawiedliwy, p. 111-113.
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.Jerzy Wyrozumski, Historia Polski do roku 1505, pp. 104–111. 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.Bronisław Nowacki, Przemysł II, p. 97.
