Pan-nationalism is a form of nationalism distinguished by being associated with a claimed national territory which does not correspond to existing political boundaries. It often defines the nation as a ‘‘cluster’’ of closely related ethnic or cultural groups. It shares the general nationalist premises that the nation is a fundamental unit of human social life, and that it is the only legitimate basis for the state.
Some pan-nationalisms, such as pan-Germanism for the Germans, concern what outside anthropologists might consider a single ethnic group (today, Austrians, German-speaking Swiss people, and others may or may not identify as "German"). For adherents of Pan-Turkism, by contrast, the suppression of the primacy of the separate national or ethnic identities of the non- Turkish Turkic peoples, like the Kyrgyz people of Kyrgyzstan, is much less accepted by non-adherents of the ideology.
