The alliance with the Comanche and Kiowa…
1852 CE to 1861 CE
One band of Southern Arapaho has become so closely allied with the Comanche that they ere absorbed into the tribe, adopt the Comanche language, and become a band of Comanche known as the Saria Tʉhka (Sata Teichas) 'dog-eaters'. (Comanche, like their Southern Shoshone forebears, do not eat dog, unlike Plains tribes.)
