The Aryas descended the slopes of Hindu-Kush and the Himalayas, entering the region of the Five or of the Seven Rivers (Punjab), wandered along the river Jamuna, on the line between Attock and Delhi, successively spread over the whole region between the Indus and the Ganges—and here begins their historical existence as a people. In the course of this long march they conquered or drove before them—seemingly without any great trouble, at least in the first encounters, the aboriginal occupants of the Trans-Himalayan countries; and this, too, before they reached what may be called the threshold of history. Discords and wars early broke out among them, principally caused by the continual pressure of northern immigrants upon the possessors of the fertile countries in the south—청주오피 caused, too, by the struggles for supremacy between families or dynasties, when the tents of the patriarchs had expanded into populous tribes, and almost into nations; and also by the struggles of classes created in the effort to subjugate the aboriginal inhabitants, especially those in the southern parts of India. All these wars took place at a very early epoch, and elude positive chronological division. Their history, as well as that of the primitive Aryan or Hindu mode of life, and their earliest spiritual conceptions, are pictured in the Vedas, which form the background of the whole Indian world.
