Why people who lived in america got the name of indians

in the  united states,  native americans  (also known as  american indians,  amerindians,  indigenous americans  or simply  indians; see  §terminology differences) are people descended from the  pre-columbian indigenous population  of the land within the country's modern boundaries. these peoples were composed of numerous distinct  tribes, bands, and  ethnic groups, and many of these groups survive intact today as  partially sovereign nations.

since the end of the 15th century, the  migration of europeans to the americas  has led to centuries of population, cultural, and agricultural transfer and adjustment between  old  and  new world  societies, a process known as the  columbian exchange. most native american groups had historically preserved their histories by  oral traditions  and artwork, which has resulted in the first written sources on the conflict being authored by europeans.[3]

at the time of first contact, the indigenous cultures were quite different from those of the proto-industrial and mostly  christianimmigrants. some of the northeastern and southwestern cultures in particular were  matrilineal  and operated on a more collective basis than the europeans were familiar with. the majority of indigenous american tribes maintained their hunting grounds and agricultural lands for use of the entire tribe. europeans at that time had  patriarchal  cultures and had developed concepts of individual  property rights  with respect to land that were extremely different. the differences in cultures between the established native americans and immigrant europeans, as well as shifting alliances among different nations in times of war, caused extensive political tension, ethnic violence, and social disruption. even before the european settlement of what is now the united states, native americans suffered high fatalities from  contact with european diseases  spread throughout the americas by the spanish to which they had yet not acquired  immunity.  smallpox epidemics  are thought to have caused the greatest loss of life for indigenous populations, although estimates of the pre-columbian population of what today constitutes the u.s. vary significantly, from one million to eighteen million.[4][5]
