All the royal houses are Germanic.
In German, the word for nobles or nobility is Adler.
Supposedly it means EAGLES because they tend to have…
Aquiline noses, i.e. the nose looks like an eagle's beak.
The Khazar empire had its capital at Atil
On the delta of the Volga river, just south of Astrakhan
Where it flows into the Caspian/Persian sea.
The name Atil for the city is of unknown etymology
But in Turkic languages, Atilar means "men of Atil".
Very similar to Adler and could be the origin of the term
German's like to use that turn of phrase.
For instance they will say "Die Elmhsorner" to refer to a company
Whose headquarters is in Elmshorn
Because the phrase literally means "the men of Elmshorn".
Some think that all Germans, and their language originate from Khazaria
Not just the Ashkenazi Jews.
Look up the king lists of early Poland, and early Austria
As the Germanic people took control of more western regions
Civilization originated on the steppes of Central Asia
The need for strong leaders and organized fighters was created
By the wide open plains with no real geographical barriers.
The early Chinese were ruled by people from the steppe
Such as the Yellow Emperor
The steppe people made armor by sewing plates made from horse hooves
On their coats.
They looked a bit like fish scales.
