In the Book of Esther they are called Pras uMaday, Persia and Media. Whatever. The whole Aryan thing is a myth, regardless of what the Persians were calling themselves in 500 BC. Vikings were sometimes red-headed and fair-skinned, like the Irish before Saint Patrick got to them, and sometimes thick-lipped and big-boned, like the Russians sometimes still are, and sometimes fair-haired and tall like the Swedes, all of whom used to Vike around a lot. Nothing special about that bunch, except looting, plundering and raping. Then they turned to commerce, which wasn’t quite as much fun, and then they became Christians. That’s the “Aryan race” that Hitler got a woody about, the blondies from Sweden. If the Persians happen to be the only true scions of this mythical race, the joke’s on him.
The book of Esther calls them that as the people from Fars were the elite of the Achaemenid empire. But they called themselves Aryans. Just as the Vedic North Indians called themselves Aryans
Nothing whatsoever to do with the Germans.
