What Caused the Aztec Empire to Fall? Scientists Uncover New Clues

In 1545, an unknown disease attacked the Aztec empire. People suffering from it may have a fever, start vomiting, and form stains on the skin. The most terrible thing is that they will bleed through their eyes, mouth, nose and then die within a few days.

In the next 5 years, this disease is called "cocoriclitis" or "plague" and occurred between 7 million and 17 million people. Scientists and historians are wondering what the cause of this magical epidemic is. Now, a group of researchers may have found the answer: Salmonella

On January 15, 2017 the scientific journal Nature Ecology & Evolution published a study on Salmonella typhimurium in the teeth of Colicotris victims. Most Americans know that Salmonella is a foodborne illness obtained by eating it like raw eggs or poultry.

S. enterica is the only bacteria found by researchers in the victim's teeth but they also reminded them that they may also contain other undetectable pathogens.

Kirsten Bos, a molecular paleontologist and co-author of recent research at the Max Planck Institute in Germany, told Guardian that "S. enterica is not convinced that it is the cause of co-infection." "We believe that it should be regarded as a strong candidate."

European invaders brought many new devastating diseases to America in the 16th and 17th centuries. Spanish intruders may take salmonella through livestock to the population of modern Mexican Azteca

In this study the origins of the bacteria have not been identified and the possibility of occurrence in the Americas remains. But even if the Spaniards do not have bacteria, they may still play a role in influencing Aztecs.

"When Europeans enter the new world, we know that they change the landscape," Persia told NPR. "They have introduced new livestock and indigenous peoples have many social dislocations that increase their susceptibility to infectious diseases."

The rise and fall of Aztec civilization The rise and fall of the Aztec empire may be the most important research field in the modern world. Among all the nomadic tribes who emigrated to Mexico, the Aztecs were the last. The Aztecs who were expelled by the tribes that were originally established started to build an empire with great wealth and power in the second half of the 15th century. Due to their ruler Itzcoatl's achievement, the empire expanded to include millions of people.

After the collapse of the Mayan empire, the great civilization of the Aztecs came to power. Aztecs are concentrated in Tenaco Lake of Tenocuttran. The Aztec capital built in the center of Lake Tescoko has a large bank road, a large rugged bridge connecting the city with the mainland. Advanced work by Aztecs allowed them to adapt to their environment like Maya and Inca. The written language of Azteca is a combination of hieroglyphs and symbols of pictures. Like the Maya, Aztec language is used for enumeration, and it is more primitive in Aztec culture, daily, records and communication. Aztecs expanded their empire by military force

Azteca: When the Inca Spaniards arrived in the New World, they discovered different Indian civilizations with many similarities. In Mexico, the Spaniard found a very stable empire called Aztecs; the Aztec empire dominated the area ranging from the eastern part of the Mexican valley in Central Mexico to the Gulf of Mexico and south to Guatemala. Aztecs built a wonderful city, forming complex social, political and religious structures. - The Incas were once a tribe who lived on the coast of the southeastern part of South America and are now known as Ecuador, Colombia, Peru, Bolivia, Argentina and northern Chile, and also Andean. The Incas also settled in Ingpilca. Inca Capitol Cusco was established in 1200. The Inca Empire has become America's largest empire. The Incas were built for war and conquest. When they conquered many areas, their population has increased to over 9 million people. Inca family residences are unique
