Explanation:

The Classic Period of America corresponds to the fourth period in which the Prehistory of America is divided for purposes of study, between 292 and 900. It is the era of splendor of the most outstanding civilizations of the continent, especially in Mesoamerica, as the Maya.

In Ancient Peru, it begins with the appearance of the militarized states of the Moche and Nazca cultures: states of territories reduced to one or few coastal valleys with a regular military force. Subsequently, the influence of the Huari culture and the Tiahuanaco culture in the area near the Collao plateau, including the valleys of the south coast, appears throughout ancient Peru.

This period is characterized because civilizations grew, built large cities using large stones that were carved for that purpose. They also improved the techniques of agriculture, goldsmithing, metallurgy and ceramics and social for publication.

relations between the soviet union and the united states were driven by a complex interplay of ideological, political, and economic factors, which led to shifts between cautious cooperation and often bitter superpower rivalry over the years. the distinct differences in the political systems of the two countries often prevented them from reaching a mutual understanding on key policy issues and even, as in the case of the cuban missile crisis, brought them to the brink of war.

the united states government was initially hostile to the soviet leaders for taking russia out of world war i and was opposed to a state ideologically based on communism. although the united states embarked on a famine relief program in the soviet union in the early 1920s and american businessmen established commercial ties there during the period of the new economic policy (1921–29), the two countries did not establish diplomatic relations until 1933. by that time, the totalitarian nature of joseph stalin's regime presented an insurmountable obstacle to friendly relations with the west. although world war ii brought the two countries into alliance, based on the common aim of defeating nazi germany, the soviet union's aggressive, antidemocratic policy toward eastern europe had created tensions even before the war ended.
