At first the Donetsk People's Republic adopted a "constitution" which stated that the Russian Orthodox Church of the Moscow Patriarchate was the official religion of the self-declared state. This was changed with the promulgation of a law "on freedom of conscience and religious organisation" in November 2015, backed by three deputies professing Rodnovery (Slavic native faith), whose members organised the Svarozhich Battalion (of the Vostok Brigade) and the Rusich Company. The new law caused the dissatisfaction of Metropolitan Hilarion of Donetsk and Mariupol of the Moscow Patriarchate church.
