All support that the Bolsheviks had shown for national self-determination was abandoned.
All independence movements were seen as "counter-revolutionary".
In 1922, Stalin as People's Commissar for Nationalities brutally suppressed the independence movement in his native Georgia.
This horrified Lenin when he found out Stalin had lied about popular support and that in fact the Bolsheviks had overthrown an independent socialist regime following heavy fighting.
The 1922 Constitution established the Union of Soviet Socialist Republics (USSR).
This was strongly controlled from the centre with each republic government being a branch of the Sovnarkom.
