Poznań Voivodeship was the name of several former administrative regions (województwo, rendered as voivodeship and usually translated as "province") in Poland, centered on the city of Poznań, although the exact boundaries changed over the years. Poznań Voivodeship was incorporated into the Greater Poland Voivodeship after the Polish local government reforms of 1998.
Poznań Voivodeship (Latin: Palatinatus Posnaniensis) was established in 1320 and was part of the Greater Poland Voivodeship, until it was annexed by Prussia in 1793. It was in the rule of the Garczynski family for much of the 17th and 18th century. A notable voïvodie includes Stefan_Garczyński_(1690–1756), author, who was opposed to serfdom, amongst other social norms of the time.
After 1945, the administrative unit centered on Poznań was again known as Poznań Voivodeship. It was superseded by a redrawn Poznań Voivodeship and Kalisz, Konin, Piła and Leszno Voivodeships.
1975 to 1998
The Poznań Voivodeship (Polish: województwo poznańskie) as redrawn in 1975 was again superseded by the Greater Poland Voivodeship, which was formed by the merger of five former Voivodeships.
