Answer:
The Aztec Empire was more a set of different peoples than a homogeneous and peaceful culture. The elite in Tenochtitlán oppressed city-states around it with heavy taxes and kept its dominance through a strong military.
Explanation:
This created many enemies of the Aztec Empire and so it happened that when the Spanish arrived these peoples joined forces with them to destroy Tenochtitlán.
It's important to remember that Aztec Empire it's not how they called themselves in the 1500s. "Aztec" is a term that began to be utilized only in the 1800s by European scholars. In the 1500s the people of Tenochtitlán called themselves Mexicas.
The Renaissance was a period of cultural and technological changes that took place at the end of the 13th century. Most of Europe was included in it but historians can divide the renaissance period into Italian and Northern Renaissance.
The Italian Renaissance was marked by cultural changes such as writers, poets, artists, sculptors - figures like Leonardo da Vinci, Petrarch, Raphael, Dante Alighieri, and others. The Italian Renaissance was marked by the attention to human detail, like muscles, hairs and other characteristics. Also, it is not so religious because it focused on worldly goods.
The Northern Renaissance is considered the movement outside Italy such as German Renaissance, French, English, Polish, Netherlands. This movement has other characteristics than the Italian one, it is more religious and focuses more on sciences and mathematics. In France architecture is the strongest feature, English renaissance was marked by literature, for example, William Shakespeare.
