Affinity between ancient Iranic peoples

Iranian-speaking peoples had once occupied a region much greater than they do today: Persia, Afghanistan, Turkestan, Southern Russia, and Eastern Europe.

Among Iranian peoples there were a certainly degree of diversity: from the sedentary, urban Persians who had founded one of the greatest civilizations, to the steppe nomads like Scythian and Samartians.

Maybe the caste system; there is a theory that all proto-Indo-European speakers had once lived in the same 'society classes' system: priest/warrior/farmer.

Rostam had to battle with his son; and so did Hildebrand. 

Add Suren to the list! 

Originally posted by King John So did Arthur, Oedipus (with his father), Zeus, Odin, and others.  So how is this not just Indo-European mythological similarities?  There are many stories that have fathers battling their sons, surely theirs more of a connection then that.  Saying that the story of Rostam and the Lay of Hildebrand are almost the same has to include more then just the fact that fathers battled their sons.

What are the differences between them? even in details, if you know?

Originally posted by King John I didn't ask for similarities I asked in what way are they, the Lay of Hildebrand and the Roskam story, almost the same as Cyrus claims. This has more to do with Cyrus's theories about Germans being Iranian people or rather having a Scythian origin than anything else.

I also believe Germanic and Iranian peoples have a common origin, you can call it Iranian, Germanic or Irano-Germanic, anyway the obvious fact is that they differed from other Indo-European peoples, they were a people who believed in Goda (Middle Persian word for God [Modern Persian khoda]) and Kianig (Middle Persian word for king [Modern Persian Kian/Kiani), these are still the most holy words in the Persian culture.

You can hardly find any relation between original Iranian-speaking peoples and Indian, Slavic or Turko-Mongol peoples, of course there were some influences from one culture to another during a long contact between these peoples, but Iranian culture can be just related to Germanic culture, not other ones, it doesn't important Iranians believed in Ahura Mazda, Zurvan or Allah, they have always said "be name Goda/khoda" (in the name of God), and also it doesn't matter that their ruler was a khshaya/shah, basileus, malik, caliph, imam, ... they have always defended their kianig/kian (king, generation), if you find something in Iranian culture unsimilar to Germanic, you can consider that it is either from an non-Iranian origin or invented by Iranians in the later periods.
