I think the downvoters must really not know much about 19th and 20th century European ethno-nationalism, or how cultural movements centered around language, religion and myth, were particularly instrumental in the formation of ethnic national identities, and what that inevitably entailed for those not in the hegemonic majorities. Nor how the invention of the past, construction of new "ancient" traditions, and a nostalgic longing for an imagined more pure mythic past served nationalist agendas among competing European states. And of course, all of this is still going on, in all sorts of places other than Europe (e.g. Africa, Asia).
But I won't complain about downvotes without an attempt to actually give people the opportunity to learn something.
