For centuries, the nomads of Central Asia lived a migratory lifestyle. They traveled, explored new land, and were not tied down to farms or an agricultural lifestyle. This behavior can be explained with ideas Harari presented about human nature in Sapiens: humans have a need to explore and make new things, as well as expanding their population. They also tend to follow their food sources; by migrating around, the nomads never really used up any particular plant or animal.
This continued with few changes until the modern era, when the Soviet Union decided to expand into Central Asia. With ethnic cleansings reducing native citizens to a minority in most of the countries, Russia was able to expand its power. They also forced Central Asia to become more like the Western world, by having nomads settle down on farms instead of constantly migrating.
Ultimately, this take over had a negative impact on Central Asia. Even now, when they are all independent countries, they are having issues with corrupt elections and politicians, poverty, and damaged infrastructures. But that's not to say that all was lost; in many parts of Central Asia, especially in rural areas, people continue to carry on the nomadic traditions and celebrations of their ancestors.
