Later the Indians were classed from language into two general divisions--the Algonquins and the Iroquois--terms given them by the Jesuit missionaries. The Iroquois occupied central and western New York, including the Mohawk River, the headwaters of the Delaware, the Great Lakes and the St. Lawrence River. The Algonquins included all the Indians of Eastern New York, Eastern Canada, New England, New Jersey, Eastern Pennsylvania, and Eastern Virginia. Several tribes in the west Hudson River counties constituted the Lenni-Lenape nation, which held its council fires on the site of Philadelphia. Some of their names were Waoranecks, Haverstroos, Minisinks and Waranawonkongs. When Hudson came the Lenapes were the head of the Algonquin nations, but wars with the Iroquois and the whites so weakened them that they became the subjects of the Iroquois confederacy for eighty years previous to 1755. Then they rebelled, allied themselves with other tribes, became the head of the western nations and successfully contested nearly all the territory west of the Mississippi. During the period of their subservience they were known as the Delawares. The Mohawks were the most eastern nation of the Iroquois, and were called Maquas by the Dutch, and a branch on the Delaware, Minquas. The Iroquois, first known as the Five Nations, later received the Tuscaroras of North Carolina, who removed to New York, and with the Cherokees and other southern Indians became the sixth nation of that great Indian confederacy, to which they also were related by language. Both the Algonquin and Iroquois confederacies were divided into tribes and sub-tribes of families, each with a head who was the father or founder. These combined for mutual defense and the heads elected one of their number chief sachem, regarding themselves as a nation to make laws, negotiate treaties, and engage in wars, the wars being mostly between the Algonquins and Iroquois. The Esopus Indians occupied parts of Orange and Ulster Counties, and their war dances were held on the Dans Kamer, a high promontory north of Newburgh. Their rule extended to other families east and west of the Hudson, but their territory cannot be clearly defined. Regarding Indian character, there have been presented by our historians some contrasting but not wholly irreconcilable views. E. M. Ruttenber, in his valuable contribution to the History of Ulster County, edited by Hon. A. T. Clearwater, says:
