The disease that the spanish brought into the Aztec Civilization was the Small Pox It infected alot of people and killed alot but fortunately some survived
Smallpox
they had diseases ... and they were died and made it stink at Aztec capital.
The Spanish desroted Tenochtitlan in 1535
Cortes' arrival in Tenochtitlan is so important in history because it shows the cause of why/how he destroyed the empire of the Aztecs. His arrival was the cause of the decline of Tenochtitlan and their people. Although he did not have that much men, he was able to kill all the Natives there because he had better weapons (guns...), horses, armor, horses, and diseases. Although they did not know it, the Spanish had diseases. They had already become immune to the diseases because they've been around for so long, but the Natives had not immunization against the diseases. This was another reason to the decline of Tenochtitlan. This is why Cortes' arrival in Tenochtilan was so important in history.
Hernan Cortes or some other spanish explorer dude.
Spanish Colony
The Spanish brought diseases such as smallpox, measles, and influenza that decimated the local populations due to lack of immunity. They also introduced forced labor systems, warfare, and exploitation of resources that contributed to the destruction of early civilizations in the Americas.

They had better weapons
The Spanish had horses, guns, swords, and cannon while the Aztecs still used hand weapons and spears. They also had the backing from tribes who disliked the Aztecs, such as the Talaxcala. However the defeat of the Aztecs and the downfall of Tenochtitlan was mainly due to the ravages of disease. Most of the population of the Aztec capital, Tenochtitlan, were wiped out by the diseases the Spanish brought, to which the natives had no immunity.
Tenochtitlan was the capital of the Aztec Empire until it was captured by the Spanish in 1521. Today, the ruins of Tenochtitlan are in the historic center of Mexico City.
I think you mean to ask what was Tenochtitlan named after the Spanish conquered the Aztec Empire. The locationis the same as present day Mexico City.
Because the complete name of such city was Mexico-Tenochtitlan. It was customary for Spanish conquistadors to keep the name of the cities they conquered.
