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. Koliada Viatichey (Russian: Коляда Вятичей) is a Rodnover faction that emerged in 1998 through the union of the group named "Viatiches", inspired to the homonymous early East Slavic tribe of the Viatiches, which comprised well-educated Moscow intellectuals and was founded by Nikolay Speransky (volkhv Velimir) in 1995, and the community named "Koliada". Koliada Viatichey refutes any non-Slavic influence in their religion, including the label "Vedic" and Vedic literature, influences from Eastern religions, influences from Roerichism and esotericism, and also the Book of Veles.

Polytheism is accepted for its ability to "account for the complexity of the world with its multiple good and evil forces", and particularly emphasised is the popular Russian belief in the great goddess of the Earth (Mokosh or Mat Syra Zemlya). Speransky has adopted the concept of Darna from Lithuanian Romuva, explaining it as ordered life "in accordance with the Earth and with the ancestors". Meryan Rodnovery Meryan Rodnovery is a movement present in the Russian regions of Ivanovo, Kostroma, Moscow, Vladimir, Vologda, Tver, and Yaroslavl. It consists in the establishment of an ethnoreligious identity among those Russians who have Meryan ancestry; Merya are Volga Finns fully assimilated by East Slavs in the historical process of formation of the Russian ethnicity. It is primarily an urban phenomenon and its adherents are Russian-speakers. Various organisations have been established in the late 2000s and 2010s, including Merjamaa and Merya Mir (Меря Мир, "Merya World"). In 2012 they presented their official flag. The scholar Pavel A. Skrylnikov notes that a salient feature of the movement is what he
