Pyzdry was first mentioned in 1232, when army of SilesianPiast Duke Henry I the Bearded entered Greater Poland. Pyzdry is one of the oldest town of the province, as in 1257 it was mentioned as a location governed by a vogt, which means that a well-established urban center must have already existed here. It is not known when Pyzdry received Magdeburg rights; most likely it happened during the reign of Duke Bolesław the Pious.
On 29 June 1318 Ladislaus the Short called at Pyzdry a meeting of Polish nobility and bishops, during which it was agreed that a delegation be sent to Pope John XXII, asking for his permission to grant Polish Crown to Ladislaus. In 1331, Pyzdry was burned to the ground by the Teutonic Knights in the Battle of Pyzdry. Following the destruction, King Casimir III of Poland ordered construction of a defensive wall with a mighty castle. In 1345, a truce between Casimir and John of Bohemia was signed here.
Following the Second Partition of Poland, Pyzdry was annexed by the Kingdom of Prussia (1793). After the successful Greater Poland uprising of 1806, it was regained by Poles, and included within the newly established, however short-lived Duchy of Warsaw. Following the duchy's dissolution in 1815, it became part of Russian-controlledCongress Poland, in which it remained until World War I, and was the westernmost point of the Russian Empire. In 1818, Pyzdry County was disbanded. During the January Uprising, on 17 April 1863, the town was captured by Polish insurgents led by Edmund Taczanowski.[5] On 29 April 1863 the Battle of Pyzdry was fought nearby, in which Polish insurgents led by Taczanowski defeated Russian troops.[6] In 1867, as punishment for the January Uprising, Russians reduced Pyzdry to the status of a village. In 1918 Poland regained independence and control of Pyzdry, and in 1919 town rights were restored.
