The USSR in Central Asia?

by Greentextbo

Hello, I’ve always been curious as to why and how northern Central Asia got its borders today, And I read that the borders were redrawn by the USSR after absorbing the Khivan and bukkharan territories. I was just wondering exactly why and how the borders were redrawn? What are their purpose? How has it affected the peoples? And why exactly were these borders decided on specifically? I’ve been trying to find direct sources on the subject but I really don’t know where to look

I wrote an answer that looks a bit at how ethnic groups in Soviet Central Asia were defined and delineated here.

Also as a bonus a more specific description of where the western border of Kazakhstan came from is here.
