Marx considered the Paris Commune to be a good example of what he had in mind.

"The Commune itself–the government formed by the workers–was made up of representatives of the various wards of Paris, elected by the citizens and recallable from office at any time. The majority of its members were workers or acknowledged representatives of the working class. Rather than a parliamentary body (such as the Congress in the U.S.), the Commune both made decisions and carried them out." — https://www.marxists.org/history/erol/ncm-5/rcp-paris-commun...
