At this time two great dangers, the one from without, the other from within, pressed upon these tribes. The Mohegans, or Mohicans, a powerful Algonkin people, whose settlements stretched along the Hudson river, south of the Mohawk, and extended thence eastward into New England, waged a desperate war against them. In this war the most easterly of the Iroquois, the Caniengas and Oneidas, bore the brunt and were the greatest sufferers. On the other hand, the two western nations, the Senecas and Cayugas, had a peril of their own to encounter. The central nation, the Onondagas, were then under the control of a dreaded chief, whose name is variously given, Atotarho (or, with a prefixed particle, Thatotarho), Watatotahro, Tadodaho, according to the dialect of the speaker and the orthography of the writer. He was a man of great force of character and of formidable qualities--haughty, ambitious, crafty and bold--a determined and successful warrior, and at home, so far as the constitution of an Indian tribe would allow, a stern and remorseless tyrant. He tolerated no equal. The chiefs who ventured to oppose him were taken off one after another by secret means, or were compelled to flee for safety to other tribes. His subtlety and artifices had acquired for him the reputation of a wizard. He knew, they say, what was going on at a distance as well as if he were present; and he could destroy his enemies by some magical art, while he himself was far away. In spite of the fear which he inspired, his domination would probably not have been endured by an Indian community, but for his success in war. He had made himself and his people a terror to the Cayugas and the Senecas. According to one account, he had subdued both of those tribes; but the record-keepers of the present day do not confirm this statement, which indeed is not consistent with the subsequent history of the confederation.
