The U.S. Cavalry on the Plains from 1850 to 1890 played a critical role in westward expansion and conflicts with Native American tribes. Following the Mexican-American War (1846-1848), the U.S. acquired vast western territories, intensifying clashes between settlers and Indigenous nations over land, resources, and cultural survival. Cavalry regiments—like the 1st, 2nd, and 7th Cavalries—were tasked with enforcing federal policies, protecting settlers, and supporting railroad construction. They also aimed to confine Native American tribes to reservations, often leading to violent confrontations.
