This right of citizenship then became precious, first, because it was complete, and secondly, because it was a privilege. Through it a man figured in… - Numa Denis Fustel de Coulanges

The ancient city, like all human society, had ranks, distinctions, and inequalities. We know the distinction originally made at Athens between the Eupatnids and the Thetes; at Sparta we find the class of Equals and that of the Inferiors; and in Euboea, that of the Knights and that of the People. The history of Rome is full, of the struggles between the Patricians and Plebeians, struggles that we find in all the Sabine, Latin, and Etruscan cities. We can even remark that the higher we ascend in the history of Greece and, Italy the more profound and the more strongly marked the distinction appears — a positive proof that the inequality did not grow up with time, but that it existed from the beginning, and that it was contemporary with the birth of cities.

The causes of ... [the city's] destruction may be reduced to two. One was the change that took place in the course of time in ideas, resulting from the natural development of the human mind, and which, in effacing ancient beliefs, at the same time caused the social edifice to crumble, which these beliefs had built, and could alone sustain. The other was a class of men who found themselves placed outside this city organization, and who suffered from it. These men had an interest in destroying it, and made war upon it continually. When, therefore, the beliefs, on which this social regime was founded, became weakened, and the interests of the majority of men were at war with it, the system fell. No city escaped this law of transformation; Sparta no more than Athens, Rome no more than Greece. We have seen that the men of Greece and those of Italy had originally the same beliefs, and that the same series of institutions was developed among both; and we shall now see that all these cities passed through similar revolutions.

It is a strong proof of the antiquity of this belief, and of these practices, to find them at the same time among men on the shores of the Mediterranean and among those of the peninsula of India. Assuredly the Greeks did not borrow this religion from the Hindus, nor the Hindus from the Greeks. But the Greeks, the Italians, and the Hindus belonged to the same race; their ancestors, in a very distant past, lived together in Central Asia. There this creed originated and these rites were established. The religion of the sacred fire dates, therefore, from the distant and dim epoch when there were yet no Greeks, no Italians, no Hindus; when there were only Aryas. When the tribes separated they carried this worship with them, some to the banks of the Ganges, others to the shores of the Mediterranean. Later, when these tribes had no intercourse with each other, some adored Brahma, others Zeus, and still others Janus; each group chose its own gods; but all preserved, as an ancient legacy, the first religion which they had known and practiced in the common cradle of their race.
