Russia [SEP] Religion
Though a secular state under the constitution, Russia is often said to have Russian Orthodoxy as the "de facto" national religion, despite other minorities: "The Russian Orthodox Church is de facto privileged religion of the state, claiming the right to decide which other religions or denominations are to be granted the right of registration". Russians have practised Orthodox Christianity since the 10th century. According to the historical traditions of the Orthodox Church, Christianity was first brought to the territory of modern Belarus, Russia and Ukraine by Saint Andrew, the first Apostle of Jesus Christ. Following the "Primary Chronicle", the definitive Christianization of Kievan Rus' dates from the year 988 (the year is disputed), when Vladimir the Great was baptised in Chersonesus and proceeded to baptise his family and people in Kiev.
