Mark Twain became showy as their counterparts in upper-class Europe. In other words, it was the major growth in population in the United States and great displays of America's upper-class during the post-Civil War and post-Reconstruction era, in the late 19th century (1877-1890). This was the age when mansions imitated European palaces. The mansions were filled with works of art, antiques, rare books and very exquisite decor. These wealthy Americans spent their leisure time attending operas, relaxing at luxurious resorts because they believed they were signs of refinement. For Native Americans, some of their problems were that their land became increasingly attractive to white settlers, while the Native Americans themselves were considered impediments to progress. Reservations were made smaller or were relocated to remote areas undesirable to whites. By the 1880s areas reserved for the Native Americans had shrunk to about 132 million acres.
Native Americans had difficulty making a living from the land, and their older cultures had been shattered by contact with whites. Not to much later, the government tried to force them to change their ways into the white American life. The plan called for breaking up reservations into allotments, then issuing the allotments to individual Native Americans. Ideally, they were to farm their plots; instead, many of them sold their allotments or leased them to whites. By 1934, Native Americans were left with only about 25 percent of the reservation land they had held in the 1880s.
A few other controversies Native Americans have suffered were whether the tribes or the government should control access to these resources. In the past, the government controlled all agreements between tribes and energy corporations. Also, The tribes have always been insisting on more authority in handling agreements. Finally, most reservations are still underdeveloped, and their inhabitants among the poorest of the nation's poor.
