Duchy of Gniezno

The Duchy of Gniezno was a feudal district duchy in Greater Poland, with its territorial and administrative core in the Gniezno Land — the region surrounding the city of Gniezno. Its capital was Gniezno. The duchy was established in 1177, following the partition of the Duchy of Greater Poland after a rebellion against Mieszko III. Duke Casimir II the Just of the Piast dynasty became its first ruler.Józef Dobosz, Kazimierz II Sprawiedliwy, p. 111-113.

Initially, Gniezno 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 Gniezno 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 Kalisz and Poznań under the rule of Przemysł II, forming a reconstituted Duchy of Greater Poland.Bronisław Nowacki, Przemysł II, p. 97.
