How many post-WWI Revolutionary movements can take power?

After the end of the First World War, many Revolutionary movements were forming. My question is how many of these movements can launch a revolution in their respective nations. Extra points if they can hold on to power.

I'm particuarly interested if any of these can be successful:
The Spartacists and Bavarian SR
Biennio rosso
Hungarian SR
Any Movements during the First Red Scare
Red Clydeside (not technically a movement but many of those involved had Revolutionary ideals)
Slovak SR

Note: Revolutions don't need to be Leftist and they must start between November 1918 and 1925.

More revolutions in the Middle East, overthrowing the remaining European colonies in the area, Arab spring nearly a century over.

How? Unlike in the metropol, I can't see large-scale mutinies of regulars against native uprisings, and outside of desert nobody cared about the regulars would be able to handily contain and mobs.

Besides, weren't most of the middle eastern colonies governed via proxy rulers?
