The indigenous civilization of Aztec and Central America has an average population of about 20 million people before Spain's conquest and is part of the most developed civilization before industrialization (Marr and Kiracoffe 2000). These same civilizations also have witnessed one of the most serious tragedies in human history, with a population loss of nearly 90% and a population of 1 million after confiscation (Marr and Kiracoffe). The tragedies of these populations are epidemics in the old and new world, and Spain is a major factor that succeeded in conquering this area.
The conquest of Mexico in Spain was often understood as Spain's conquest of the Aztec empire (1519-21), which later became the basis for conquest of other areas. The subsequent conquest was a prolonged fight, and the result was not as good as conquering Azteca. Spain conquered Yucatán and Spain conquered Guatemala, the Western Mexican war and the Northern Mexican war in Chithemeka expanded control over Spain's territory and indigenous peoples. But until Spain conquered Peru, it conquered the Aztec team and in 1532 only matched the victory of the Inca Empire.
In the Spanish conquest of past conquest of Mexico, the most unfixed view was the details of the party tactical system and how these systems worked on the battlefield to create victory for Spain . In this paper, we examine this concept from a strategic point of view and apply military historical viewpoints to the historical texts of the country and data collected from contemporary works. The result shows that Spanish infantry tactics and cavalry are important elements of Spain's victory. Most of the explanations for the conquest of Spain in Aztecs are psychosocial factors - Aztecs have different concepts of war - or they are stunned by Quetzalcoatl - or to technical factors like so-called Spanish victory Excellent firearms and steel swords, or a combination of the two.
