This article examines the process of national identity formation among ethnic minorities in the Crimea - specifically, the moderation effects of concepts of national identity on interrelations between conflict indicators and readiness for conflict or compromise for two ethnic minorities in Crimea. Based on a survey in the Crimea, results show that concepts of national identity moderate the effects of ethnic identity, ethnocentrism and economic deprivation on individual conflict behaviour. Research show that civic concept of national identity significantly reduces readiness for conflict among ethnic minorities. The position of a minority within the nation regulates impact of ethnic and multicultural concepts on readiness to fight with other groups.
