Russian Empire - Pupulation by religion believers (1897)

The Russian Empire's state religion was Orthodox Christianity. The Emperor was not allowed to ″profess any faith other than the Orthodox″ (Article 62 of the 1906 Fundamental Laws) and was deemed ″the Supreme Defender and Guardian of the dogmas of the predominant Faith and is the Keeper of the purity of the Faith and all good order within the Holy Church″ (Article 64 ex supra). Although he made and annulled all senior ecclesiastical appointments, he did not determine the questions of dogma or church teaching. The principal ecclesiastical authority of the Russian Church that extended its jurisdiction over the entire territory of the Empire, including the ex-Kingdom of Kartli-Kakheti, was the Most Holy Synod, the civilian Over Procurator of the Holy Synod being one of the council of ministers with wide de facto powers in ecclesiastical matters. All religions were freely professed, except that certain restrictions were laid upon the Jews and some marginal sects. According to returns published in 1905, based on the Russian Imperial Census of 1897, adherents of the different religious communities in the whole of the Russian empire numbered approximately as follows.
