“Statutes on Conscription Duty” (Ustav rekrutskoi povinnosti”) of Nicholas I [Russia] [Unconfirmed]
Commentary from other sources:
1) “When on 26 August 1827 Nicholas I (r. 1825–1855) issued his Ustav rekrutskoi povinnosti (Statute on Conscription Duty) making Jews in Russia liable to personal army service and canceling their prior privilege of providing money ransom instead of conscripts, he followed a policy consistent with European enlightened monarchies, which sought to transform ‘their’ Jews from a medieval corporate entity into useful subjects integrated into the society with which Jews shared rights and obligations.””Yet some differences between Jews and non-Jews applied: most significantly, Jews were required to provide conscripts between the ages of 12 and 25, whereas for others the conscripts were between 18 and 35.”

2) In Russia, there were many instances of coercion to convert the Jews. In 1827, Tsar Nicholas I sought to sever Jewish boys from their religious and cultural roots by impressing them into 25 years of military service, a more onerous term than Christian males endured. The Tsar hoped to make the young Jewish soldiers both Russian and Christian.
