It won't always be the same ones so I'm unsure of what you're asking. Which ones invaded the spaces I listed before?

For Revolutionary Catalonia it was the Nationalist Faction who overthrew them. They advocated for, and implemented, a form of national syndicalism that was "fully compatible with capitalism".

For Red Vienna is was the fascists who overturned the socialist policies and returned the city to a state of capitalism, allowing land-leeches and other bourgeoise to return to continue exploiting the working class.
