Ostroróg

The town's location was confirmed by the Polish king Sigismund I the Old in 1546.

[5] Jan Ostroróg, Polish Renaissance political writer and statesman, was born there in 1436.

After 1624, it often changed owners, it was the property of Potocki, Rej, Górski, Radziwiłł, Zaleski, Malechowski, Sapieha and Kwilecki families.

After the successful Greater Poland uprising of 1806, it was regained by Poles and included within the short-lived Duchy of Warsaw.

In 1815 it was annexed again by Prussia, initially as part of the autonomous Grand Duchy of Poznan.
