Mayan, Inca And Aztec

From watching these three documentaries, one observes the total war of the Mayan, Inca and Aztecs with the Spanish Empire who had an advantage with guns and gun powder.

The first great civilization in South America, the Mayans were people who lived and farmed the lands of the southern Yucatan, before the Incas of the tall mountains in Peru and the Aztecs of the high-altitude plains of Mexico. Links to their ancient heritage devastated by “cultural reform”, current academics are mending the ancient language of their hieroglyphs.

 
The Mayan civilization was followed by the great civilization of the Inca. The Incas were people who lived in the tall mountains of Peru and the surrounding lush countryside. “The Inca Empire, also known as the Inka Empire or Incan Empire, was the largest empire in pre-Columbian America. The administrative, political, and military center of the empire was located in Cusco in modern-day Peru. The Inca civilization arose from the highlands of Peru..”

 
Then rose the Aztecs, who farmed the high-altitude plains of Mexico, a region north of the mountains in Peru (home of the Incas) and the low-altitude river valley in the southern Yucatan (home of the Mayans).
