In 1706 was the great battle close to Kalisz between Saxon and Swedish armies that involved 50,000 soldiers all together. The Saxon army helped by the Russian army defeated Swedish army and Polish soldiers led by Stanisław Leszczyński.

In 1793, following the Second Partition of Poland, the town was annexed by Prussia, and the archbishops' property was confiscated by the Prussian authorities. After the successful Greater Poland uprising of 1806, the town was regained by Poles and included within the short-lived Duchy of Warsaw. Since 1807 it belonged to general Józef Zajączek, the future governor of the Congress Poland. In that time many buildings designed by the most outstanding architects were constructed; moreover, the governor carried out reforms in his property which enabled the economical development in this area.
