In American politics after the War of 1812; Manifest Destiny was the ideological movement during America’s expansion West. The movement incorporated expansionist nationalism with Continentalism, with the Mexican War in 1846-1848 being attributed to it. Despite championing American settlers and traders as the people whom the Government’s military would be aiding, the Bent, St. Vrain and Company stated to be the most influential Indian Trading company prior to the Mexican War, underwent a decline due to War and traffic from American settlers by Beyreis. The company also lost Partner Charles Bent on January 19, 1847, to a riot caused by the Mexican War. The tribes: Cheyennes, Comanches, Kiowas, and Pawnees died from Smallpox in 1839-1840, measles and whooping cough in 1845, and cholera in 1849 brought by white settlers. The buffalo herds, sparse grasses, and rare waters were also depleted following the war as increased traffic by settlers moving to California during the Gold Rush.
