d.) russification

Russification has been a Russian policy of attempting to integrate and assimilate non-Slavic communities during Imperial, Soviet, and modern times. Russification involves creating it as an official language, secularization, and changing names to Slavic patronymic and family name ending conventions. Opposing factors to Russification continue in the form of it being seen as attempts to eradicate national, tribal and religious identity. Russification forms a core to the conflict of claims to Caucuses, and to the higher issue of Islam in Russia.
