Modern Rodnovery in the Czech Republic emerged in 1995–1996. Two groups were founded in those years, the National Front of the Castists ("Národní Front Castistů", where "Castists" was created as a neologism from Latin "castus", meaning "pure") and the "Radhoŝť" group, founded by the Naples-born anthropologist and professor of Slavic languages Giuseppe Maiello (whose Slavic name is Dervan) among the students of the Faculty of Philosophy of Charles University in Prague. The two groups, respectively renamed "Kin of Yarovit" and "Kin of Mokosh", merged in 2000 to form the Commonwealth of Native Faith ("Společenství Rodná Víra"). In 1995, one of the future founders of the organisation, Radek Mikula (Ratko), had established contacts with Vadim Kazakov, leader of the Russian Union of Slavic Native Belief Communities; the relationship continued in the 2000s and led to "Rodná Víra" becoming an official subgroup of the Russian organisation until 2002, while it nurtured ties with Polish and Slovak Rodnovers too. In the mid 2000s "Rodná Víra" was legally registered by the Czech government, but internal disagreements culminated with its unregistration in 2010 and transformation into an informal association. Conflicts emerged around the interpretation of ancient Slavic religion: The Kin of Yarovit focused on elements of puported Indo-European origin and their social trifunctionalism as proposed by Georges Dumézil, the Kin of Mokosh focused on elements of purported Neolithic European Mother Goddess worship, while groups which emerged later, such as the "Kin of Veles", had no focus.
