As part of the region of
Greater Poland, i.e. the cradle of the Polish state, the area formed part of Poland since its establishment in the 10th century. It was a private village of
Polish nobility, administratively located in the Poznań County in the
Poznań Voivodeship in the
Greater Poland Province. The last owners of the village and palace, until 1939, were the
Mielżyński family. Afterwards, Iwno was converted into a premier horse farm and riding school. During the
German occupation of Poland (
World War II), the local school principal and the local estate administrator were among the victims of a massacre of
Poles committed by the Germans in nearby
Kostrzyn on 20 October 1939, as part of the genocidal
Intelligenzaktion campaign. ==Sights==
