After the conquest of Kazan by the Russians in the sixteenth century, the occupation of the former Tatar Khanate was followed up by an official Christian missionary movement, and a number of the heathen population of the Khanate were baptised, the labours of the clergy being actively seconded by the police and the civil authorities, but as the Russian priests did not understand the language of their converts and soon neglected them, it had to be admitted that the new converts “shamelessly retain many horrid Tartar customs, and neither hold nor know the Christian faith.” When spiritual exhortations failed, the government ordered its officials to “pacify, imprison, put in irons, and thereby unteach and frighten from the Tartar faith those who, though baptised, do not obey the admonitions of the Metropolitan.” In the eighteenth century the Russian government made fresh efforts to convert the heathen tribes and the relapsed Tatars, and held out many inducements to them to become baptised. Catherine II in 1778 ordered that all the new converts should sign a written promise to the effect that “they would completely forsake their infidel errors, and, avoiding all intercourse with unbelievers, would hold firmly and unwaveringly the Christian faith and its dogmas.” But in spite of all, these so-called “baptised Tartars” were Christians only in name, and soon began to try to escape from the propagandist efforts of the Orthodox Church and abandoned Christianity for Islam, their so-called conversion merely serving as a stepping-stone to their entrance into the faith of the Prophet.
