 The settlement was established in the 1230s by the Piast duke Władysław Odonic, then ruling over the Polish duchy of Greater Poland.It became a border town after the adjacent Lubusz Land in the west had passed to the Margraves of Brandenburg in 1248 as part of their "Neumark" territories.In the early 14th century, the Ascanian margrave Waldemar occupied the Bledzew area and granted it to the Cistercian monks at Zemsko; it nevertheless was reconquered by the Polish king Władysław I the Elbow-high in 1326 and incorporated into the Poznań Voivodeship of the Polish Crown.
