The U.S. government’s policies towards Native Americans in the second half of the nineteenth century were influenced by the desire to expand westward into territories occupied by these Native American tribes. By the 1850s nearly all Native American tribes, roughly 360,000 in number, lived to the west of the Mississippi River. These American Indians, some from the Northwestern and Southeastern territories, were confined to Indian Territory located in present day Oklahoma, while the Kiowa and Comanche Native American tribes shared the land of the Southern Plains.

The Sioux, Crows and Blackfeet dominated the Northern Plains. These Native American groups encountered adversity as the steady flow of European immigrants into northeastern American cities pushed a stream of migrants into the western lands already occupied by these diverse groups of Indians.

The early nineteenth century in the United States was marked by its steady expansion to the Mississippi River. However, due to the Gadsden purchase, that lead to U.S. control of the borderlands of southern New Mexico and Arizona in addition to the authority over Oregon country, Texas and California; America’s expansion did not end there. Between 1830 and 1860 the United States nearly doubled the amount of territory under its control. These territorial gains coincided with the arrival of troves of European and Asian immigrants who wished to join the surge of American settlers heading west. This, partnered with the discovery of gold in 1849, presented attractive opportunities for those willing to make the long journey westward. Consequently, with the military’s protection and the U.S. government’s assistance, many settlers began building their homesteads in the Great Plains and other parts of the Native American tribe inhabited West.

Native American Policy can be defined as the laws and operations developed and adapted in the United States to outline the relationship between Native American tribes and the federal government. When the United States first became an independent nation, it adopted the European policies towards these native peoples, but over the course of two centuries the U.S. adapted its own widely varying policies regarding the changing perspectives and necessities of Native American supervision. In 1824, in order to administer the U.S. government’s Native American policies, Congress made a new agency within the War Department called the Bureau of Indian Affairs, which worked closely with the U.S. Army to enforce their policies. At times the federal government recognized the Indians as self-governing, independent political communities with varying cultural identities; however, at other times the government attempted to force the Native American tribes to abandon their cultural identity, give up their land and assimilate into the American culture.  The U.S. government’s policies towards Native Americans in the second half of the nineteenth century were influenced by the desire to expand westward into territories occupied by these Indian tribes.

With the steady flow of settlers into Indian controlled land, Eastern newspapers published sensationalized stories of cruel native tribes committing massive massacres of hundreds of white travelers.  Although some settlers lost their lives to American Indian attacks, this was not the norm; in fact, Native American tribes often helped settlers cross the Plains.  Not only did the American Indians sell wild game and other supplies to travelers, but they acted as guides and messengers between wagon trains as well. Despite the friendly natures of the American Indians, settlers still feared the possibility of an attack. 

question - in 1827, john walker, a druggist in a small english town, tipped a splint with sulphur, chlorate of potash, and sulphid of antimony, and rubbed it on sandpaper, and it burst into flame. the druggist had discovered the first friction-chemical match, the kind we use to-day. it is called friction-chemical because it is made by mixing certain chemicals together and rubbing them. although walker's match did not require the bottle of acid, nevertheless it was not a good one. it could be lighted only by hard rubbing, and it sputtered and threw fire in all directions. in a few years, however, phosphorus was substituted on the tip for antimony, and the change worked wonders. the match could now be lighted with very little rubbing, and it was no longer necessary to have sandpaper upon which to rub it. it would ignite when rubbed on any dry surface, and there was no longer any sputtering. this was the phosphorus match, the match with which we are so familiar. according the paragraph what was the benefit of the new phosphorus match? it burst into flame when rubbed on sandpaper. it was made by mixing chemicals. it could be ignited on any dry surface. it threw fire in all directions.

answer - matches required natural chemicals

answer; no longer than a reasonable period of time;
