In 900 AD, several significant events took place across different regions of the world, marking an important period in various cultural and political developments.
One of the notable occurrences was the rise of the powerful Toltec civilization in Mesoamerica. The Toltecs, who were thought to have succeeded the declining Teotihuacan, began to exert their influence, particularly in what is now central Mexico. They are often credited with establishing a cultural foundation that would influence later civilizations, including the Aztecs.
In Europe, the early medieval period was characterized by the gradual decline of the Carolingian Empire, which had been established by Charlemagne. By 900 AD, Europe was fragmented into various kingdoms and territories, paving the way for the feudal system that became prominent in the subsequent centuries.
Meanwhile, in Asia, the Tang Dynasty in China was nearing its end, leading to a time of political instability and the eventual fragmentation of the empire during the Five Dynasties and Ten Kingdoms period. This period was marked by constant warfare and the rise and fall of various regional powers.
Overall, 900 AD was a year of transition, marked by the rise of new powers and the decline of established empires across different regions.
