Kaliszanie
Kaliszanie (Polish pronunciation: [kaliˈʂaɲɛ], those from Kalisz) or Kalisz Opposition was a semi-formal political group opposed to the conservative authorities of the Kingdom of Poland in the period preceding the outbreak of the November Uprising. The circle was formed around 1820 by brothers Bonawentura and Wincenty Niemojowski, two liberal politicians from the western provinces of Poland.
