The Iroquois in some measure owed their triumphs to the position of their country; for they dwelt within the present limits of the State of New York, whence several great rivers and the inland oceans of the northern lakes opened ready thoroughfares to their roving warriors through all the adjacent wilderness. But the true fountain of their success is to be sought in their own inherent energies, wrought to the most effective action under a political fabric well suited to the Indian life; in their mental and moral organization; in their insatiable ambition and restless ferocity. In their scheme of government, as in their social customs and religious observances, the Iroquois displayed, in full symmetry and matured strength, the same characteristics which in other tribes are found distorted, withered, decayed to the root, or, perhaps, faintly visible in an imperfect germ. They consisted of five tribes or nations——the Mohawks, the Oneidas, the Onondagas, the Cayugas, and the Senecas, to whom a sixth, the Tuscaroras, was afterwards added.[9] To each of these tribes belonged an organization of its own. Each had several sachems, who, with the subordinate chiefs and principal men, regulated all its internal affairs; but, when foreign powers were to be treated with, or matters involving the whole confederacy required deliberation, all the sachems of the several tribes convened in general assembly at the great council-house, in the Valley of Onondaga. Here ambassadors were received, alliances were adjusted, and all subjects of general interest discussed with exemplary harmony.[10] The order of debate was prescribed by time-honored customs; and, in the fiercest heat of controversy, the assembly maintained its self-control. But the main stay of Iroquois polity was the system of _totemship_. It was this which gave the structure its elastic strength; and but for this, a mere confederacy of jealous and warlike tribes must soon have been rent asunder by shocks from without or discord from within. At some early period, the Iroquois probably formed an individual nation; for the whole people, irrespective of their separation into tribes, consisted of eight totemic clans; and the members of each clan, to what nation soever they belonged, were mutually bound to one another by those close ties of fraternity which mark this singular institution. Thus the five nations of the confederacy were laced together by an eight-fold band; and to this hour their slender remnants cling to one another with invincible tenacity.
