Note 3 — Group I. THREE RIVAL CIVILIZATIONS. (continued 2)

Sioux, properly Dacotahs, may be nominally divided in two great bodies by the Mississippi River. Those living on the east side were Eastern Sioux, those on the west, Western Sioux. Their country reached from the westernmost tributaries of the Mississippi to Lake Superior. In power, they were to the West what the Iroquois were to the East—the scourge of weaker nations. The Sioux ceded their lands east of the Mississippi to the United States, in 1837, living on the St. Peter's till the massacres of 1862-63 drove them thence.
