Ethnic nationalism is a form of nationalism wherein the “nation” is defined in terms of ethnicity.
The central theme of ethnic nationalists is that “nations are defined by a shared heritage, which usually includes a common language, a common faith, and a common ethnic ancestry”. It also includes ideas of a culture shared between members of the group, and with their ancestors, and usually a shared language; however it is different from purely cultural definitions of “the nation” (which allow people to become members of a nation by cultural assimilation) and a purely linguistic definitions (which see “the nation” as all speakers of a specific language). Herodotus is the first who stated the main characteristics of ethnicity, with his famous account of what defines Greek identity, where he lists kinship (Greek: ὅμαιμον, homaimon, “of the same blood”), language (Greek: ὁμόγλωσσον, homoglōsson, “speaking the same language”), cults and customs (Greek: ὁμότροπον, homotropon, “of the same habits or life”).
The central political tenet of ethnic nationalism is that ethnic groups can be identified unambiguously, and that each such group is entitled to self-determination.
The outcome of this right to self-determination may vary, from calls for self-regulated administrative bodies within an already-established society, to an autonomous entity separate from that society, to a sovereign state removed from that society. In international relations, it also leads to policies and movements for irredentism to claim a common nation based upon ethnicity.
In scholarly literature, ethnic nationalism is usually contrasted with civic nationalism. Ethnic nationalism bases membership of the nation on descent or heredity, often articulated in terms of common blood or kinship—rather than on political membership. Hence, nation-states with strong traditions of ethnic nationalism tend to define nationality or citizenship by jus sanguinis (the law of blood, descent from a person of that nationality) while countries with strong traditions of civic nationalism tend to define nationality or citizenship by jus soli (the law of soil, birth within the nation-state). Ethnic nationalism is therefore seen as exclusive, while civic nationalism tends to be inclusive. Rather than allegiance to common civic ideals and cultural traditions, then, ethnic nationalism tends to emphasise narratives of common descent.
The theorist Anthony D. Smith uses the term “ethnic nationalism” for non-Western concepts of nationalism as opposed to Western views of a nation defined by its geographical territory. Diaspora studies scholars extend this non-geographically bound concept of “nation” among diasporic communities, at times using the term ethnonation or ethnonationalism to describe a conceptual collective of dispersed ethnics.
Ethnic nationalism is also present in many states’ immigration policies in the form of repatriation laws. States such as Armenia, Bulgaria, Croatia, Finland, Germany, Greece, Hungary, Ireland, Israel, Italy, Romania, Russia, Serbia, and Turkey provide automatic or rapid citizenship to members of diasporas of their own dominant ethnic group, if desired. For example, Israel’s Law of Return, grants every Jew the right to settle in Israel and automatically acquire citizenship.
In Germany, citizenship is open to ethnic Germans (see also German nationality law). According to the Greek nationality law, Greeks born abroad may transmit citizenship to their children from generation to generation indefinitely. As of 2013 this is also true in the case of the Philippine nationality law which, has conferred Philippine citizenship on children born after October 15, 1986, with at least one Philippine citizen parent.
On the other hand, civic nationalism defines membership as an individual’s duty to observe given laws and in turn receive legal privileges.
A nation-state for the ethnic group derives political legitimacy from its status as homeland of that ethnic group, from its protective function against colonization, persecution, or racism, and from its claim to facilitate the shared cultural and social life, which may not have been possible under the ethnic group’s previous status as an ethnic minority.
