This rich region having always invited conquest, its present population is seen to consist of different layers left by successive invasions. First, we have fragments of a pre-historic people, chiefly in the hill districts to which they were driven ages ago, whose very tribe-names, meaning _slaves_ or _labourers_, sometimes tell how once they became subject to stronger neighbours; but behind them again there are traces of even older aborigines. Next, the open parts of the country are found over-run by a fair-skinned Aryan race, of the same stock as ourselves, whose pure descendants are the high-caste Brahmins and Rajpoots of our day, while a mixture of their blood with that of the older tribes has produced the mass of the Hindoo inhabitants. Over them lie patches of another quality of flesh and blood, deposited by the fresh streams of Moslem inroad, as in the case of our Saxons and Normans. But whereas with us, Briton, Saxon and Norman are so welded into one nation, unless in mountainous retreats, that most Englishmen hardly know what blood runs mingled in their veins, here a very imperfect fusion has taken place between varied peoples, held jealously aloof by pride of race, by superstition, by hatred of rival faiths, and still speaking many different languages, with the mongrel mixture called Hindostani as the main means of intercommunication. The peculiarity of the latest conquest, our own, is that the dominant strangers show small desire to settle for life in the country subject to them, yet we have added a new element in the half-caste or Eurasian strain, through which, also, and but slightly by other means, have we been able to affect the religious belief of this motley population. Religion may be taken as the keynote of Indian life and history. While our ancestors were still dark-minded barbarians, their Aryan kinsmen, migrating to Hindostan, had developed a singular degree of culture, especially in religious thought. Before Greece or Rome became illustrious, the hymns of the Vedas bespeak lofty ideas of the unseen, and the Brahminical priesthood appear as philosophers, legislators and poets of no mean rank. The first historical notices of India show a high level, not only of material but of moral civilization, as well as a manly temper of warriors well able to defend the soil they had won.
