Tochariansball were mummies 2balls who lived near the Tarim Basin. They lived in modern-day Xinjiang long before the modern day Turks arrived, and were the dominating culture until mass migration of the turks from mongolia and chinese settlers killed off the Tocharian people and their society.
History
Aside from the Indo-Iranianballs (who they preceded by centuries) the Tocharianballs were the only ones to move east rather than west like most other 2balls. They could be considered one of if not the oldest 2balls to have split off, as rather than using a satem language like the much later Indo-Iranianballs, the Tocharianballs used an ancient centum language like Gaulball and Germaniaball. Centuries after coming to modern-day Xinjiangball, the Tocharians created their own civilizations. These were very Buddhist, and used ancient brahmi script as a writing system. Eventually, city-stateballs began popping up, such as Kuchaball. These ran through the silk road that was used for trade, meaning these places thrived.
While these places did become important trade centers, the Tocharianballs were still overshadowed by larger empires that came to settle the Tarim basin. The first to control the Tocharianballs were the nomadic Xiongnuball. After this confederacy collapsed, the Chinese Hanball laid claim to the clay. Several empires came and went, and as time went on, so did the Tocharianballs.
Beginning in the 8th century, Tangball sought to conquer all of China. One of the lands that they went after was the Tarim basin. Tangball was cruel, killing millions of Tocharianballs so that the ancient 2ball was barely alive. When Uyghurball came along, they easily replaced the Tocharianballs and as a result, Tochariansball died.
