The Supreme People's Council ( (NRL)) was a political organization in the Prussian Partition of Poland, which played a major role during the Greater Poland Uprising. It was established in 1916 in Poznaà  as an underground Interparty Committee (), also known as the Central Citizensâ Committee (). After the World War I armistice, the committee renamed itself to the People's Council and later to the Supreme People's Council. The Council self-disbanded on August 19, 1919, when power in the area was transferred to the re-united Second Polish Republic.
