There are branches of Rodnovery striving to reconstruct not a pan-Slavic religion, but the specific religions of the early Balto-Slavic or Slavic tribes. In Belarus and the neighbouring regions of Russia there are groups taking inspiration from the Kriviches, of one of the tribal unions of the early East Slavs, mixing Slavic and Baltic traditions. It is represented by organisations such as the Centre of Ethnocosmology–Kriya (Belarusian: Цэнтр Этнакасмалогіі "Крыўя") by Syargei Sanko and the Tver Ethnocultural Association–Tverzha (Russian: Тверское Этнокультурное Объединение "Твержа") founded in 2010.
