Explanation:
a) It is noteworthy that the lives of American Indians have often been sometimes been interpreted differently by historians. This is evident in the case of Berkhofer Jr. and Neal Salisbury. While Berkhofer's view is that the Native Americans consisted of a diverse group of other groups from among the continent. Neal Salisbury recounts their history as a single one, affecting peoples who were linked together in some way, not multiculturally diverse.
b) A popular example, is the defeat of the Aztec empire in 1519 by the Spanish empire. Findings show that the other Native American nations helped or allied with the Spanish to bringdown the Aztec empire even though they too were natives. This thus supports Berkhofer's view that the history of Native Americans consisted of diverse groups of peoples.
c) Salisbury's view was that the Native American history, is a single one, affecting peoples who were linked together in some way.
For example, the native tribes agreed to form a representative political identity called, the<em> </em><em>" Iroquois Confederacy" </em><em>around 1500. </em>This action by the tribes indicates a kind of unity or shared interest among them.
