Koźmin

Koźmin in Greater Poland was mentioned in 1232 and developed as a town during the thirteenth century. In 1338 King Casimir the Great granted it to Maćko Borkowic, who built a castle. The town subsequently passed between noble families, including the Koźmiński family from 1471.

A Jewish community had become substantial by 1622. The castle received King Sigismund III and his son Władysław in 1623. After the second partition of Poland in 1793 Koźmin came under Prussian rule; a fire in 1797 destroyed part of its Jewish quarter.
