What time period was the war that the tribe of Native Americans historically living on the plains of Colorado and Wyoming fought in against the United States?
Red Cloud's War Red Cloud's War (also referred to as the Bozeman War or the Powder River War) was an armed conflict between the Lakota, Northern Cheyenne, and Northern Arapaho on one side and the United States in Wyoming and Montana territories from 1866 to 1868. The war was fought over control of the western Powder River Country in present north-central Wyoming. This grassland, rich in buffalo, was traditionally Crow Indian land, but the Lakota had recently taken control. The Crow tribe held the treaty right to the disputed area, according to the major agreement reached at Fort Laramie in 1851. All involved in "Red Cloud's War" were parties in that treaty.
Great Raid of 1840 The Great Raid of 1840 was the largest raid ever mounted by Native Americans on white cities in what is now the United States. It followed the Council House Fight, in which Republic of Texas officials attempted to capture and take prisoner 33 Comanche chiefs who had come to negotiate a peace treaty, killing them together with two dozen of their family and followers. The Comanche tribe was supposed to have brought white hostages as their part of the negotiations but only brought one young girl who was mutilated. Arguments and fighting then broke out among the Texans and Comanches. The Texas Officials were determined to force the Comanche to release all white captives among them. To avenge what the Comanche viewed as a bitter betrayal by the Texans, the Comanche war chief Buffalo Hump raised a huge war party of many of the bands of the Comanche, and raided deep into white-settled areas of Southeast Texas.
