[PAR] [TLE] Red Cloud's War [SEP] 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. [PAR] [TLE] Arapaho [SEP] The Arapaho ( ; in French: "Arapahos, Gens de Vache") are a tribe of Native Americans historically living on the plains of Colorado and Wyoming.  They were close allies of the Cheyenne tribe and loosely aligned with the Lakota and Dakota.  The Arapaho language, "Heenetiit", is an Algonquian language closely related to Gros Ventre (Ahe/A'ananin), whose people are considered to have separated from the Arapaho at an early time.  The Blackfeet and Cheyenne also speak Algonquian languages, but theirs are quite different from Arapaho.
