Location: Assisi

Pope Innocent IV canonised Bishop Stanislaus, whose cult became a symbol of the reunification of the Polish lands. Within the broader Fragmentation period: After 1138 Poland split into duchies ruled by rival Piast princes. Mongol invasions, German settlement, the growth of towns and the arrival of the Teutonic Knights reshaped the land before it was reunited. At this point in the timeline (8 September 1253), the governing authority was Bolesław V the Chaste (High Duke of Poland). His long reign saw Mongol raids, the canonisation of St Stanislaus and the chartering of Kraków under Magdeburg law. Canonisation of St Stanislaus mattered because religion shaped Polish identity, culture and the country's place in Europe. The event is placed here so readers can follow it alongside changes in government, warfare, society, religion and culture across Polish history.
