After India take China.

There too history exhibits conquests similar to the conquest of Europe by the Germans; and there too, more than once, the barbaric conquerors settled amidst a population of the conquered.

What was the result?
The conquered all but absorbed the conquerors, and changelessness was still the predominant characteristic of the social condition.

In Western Asia, after the invasions of the Turks, the separation between victors and vanquished remained insurmountable; no ferment in the heart of society, no historical event, could efface this first effect of conquest.

In Persia, similar events succeeded one another; different races fought and intermingled; and the end was irremediable social anarchy, which has endured for ages without any change in the social condition of the country, without a shadow of any development of civilization.
So much for Asia.
