When on holiday in Turkey a few years ago, I came across a completely ridiculous (but it seemed widely propagated) view of turkish origins in a museum. Basically this claimed that the Turkish people originated in TURKEY, mysteriously all migrated into Asian in about 3000 BC, and mysteriously all "returned" to Asia minor in about 1300 AD or whenever the historical arrival of the Turks was.
Wow. That's ... um... nuts. Well, I guess it makes as much sense as the whole Aryan race crap that the Nazis invented...
But why would they do such a thing? Turkish history is very interesting and very militaristic, no need to make things up to make people proud...
