The National Day of the Victorious Greater Poland Uprising is observed in Poland every December 27 to commemorate the military uprising of Poles against German rule that took place from 1918 to 1919. This day marks the anniversary of the uprising's outbreak, which was inspired by a patriotic speech from pianist Ignacy Paderewski in Poznań. The uprising aimed to reclaim the Greater Poland region, which had been under German control since the Third Partition of Poland in 1795. The celebration was initiated by various organizations, including the Wielkopolska Museum of Independence and the Institute of National Remembrance, and was officially recognized as a state holiday by Polish authorities in 2021. Commemorative ceremonies and educational events are held to highlight the significance of the uprising in Poland’s history and sovereignty. Although it is a state holiday, it typically remains a working day unless it falls on a weekend.
