integration with the rest of American society, the "ultimate incorporation into the great body of our citizen population". This allowed for the development of dozens of riverfront towns along the Missouri River in the new Nebraska Territory, which was carved from the remainder of the Louisiana Purchase after the Kansas–Nebraska Act. Influential pioneer towns included Omaha, Nebraska City, and St. Joseph. American attitudes towards Natives during this period ranged from malevolence ("the only good Indian is a dead Indian") to misdirected humanitarianism (Indians live in "inferior" societies and by assimilation into white society they can be redeemed) to somewhat realistic (Native Americans and settlers could co-exist in separate but equal societies, dividing up the remaining western land). Dealing with nomadic tribes complicated the reservation strategy and decentralized tribal power made treaty making difficult among the Plains Indians. Conflicts erupted in the 1850s, resulting in various Indian wars. In these times of conflict, Natives become more stringent about white men entering their territory. Such as in the case of Oliver Loving, they would sometimes attack cowboys and their cattle if ever caught crossing in the borders of their land. They would also prey upon livestock if the food was scarce during hard times. However, the relationship between cowboys and Native Americans were more mutual than they are portrayed, and the former would occasionally pay a fine of 10 cents per cow for the latter to allow them to travel through their land. Natives also preyed upon stagecoaches travelling in the frontier for its horses and valuables. After the Civil War, as the volunteer armies disbanded, the regular army cavalry regiments increased in number from six to ten, among them Custer's U.S. 7th Cavalry Regiment of Little Bighorn fame, and the African-American U.S. 9th Cavalry Regiment and U.S. 10th Cavalry Regiment. The black units, along with others (both cavalry and infantry), collectively became known as the Buffalo Soldiers. According to Robert M. Utley: Social history Democratic society Westerners were proud of their leadership in the movement for democracy and equality, a major theme for Frederick Jackson Turner. The new states of Kentucky, Tennessee, Alabama, and Ohio were more democratic than the parent states back East in terms of politics and society. The Western states were the first to give women the right to vote. By 1900 the West, especially California and Oregon, led the Progressive movement. Scholars have examined the social history
