Simply put, by coercion.
There was a very simple process that followed:
(1) the Red Army invades the countries, on the pretext of "liberating" them - this gives a plausible veneer to a treacherous end;
(2) whilst occupying, Soviet commissars would prop up the local communist party (typically, enjoying only minimal support from the country's population, unless also nationalist) - this is so as to have a puppet regime-in-waiting;
(3) under Soviet occupation, typically some sort of a "referendum" or "plebiscite" will be held, at which SUDDENLY the voters will "decide" to abolish the previous constitution and to enact one that practically gives sole powers to the local communists - this is to give the effective coup d'etat a veneer of legitimacy;
(4) once installed in power, the communist party will effectively take over the machinery of state by staffing all key posts with its members;
(5) through the use of secret police and kangaroo courts, opposition, incl. those of the original governing class who did not have the good sense to escape, will be physically eliminated, sentenced to long prison terms, exiled, otherwise incarcerated;
(6) a the takeover of the state is usually followed by a takeover, through nationalisation or outright confiscation, of the economy, giving the regime financial muscle;
<span>(7) the established position will be upheld by the same means it was acquired and with unparalleled degree of ruthlessness, with the country taken over being treated as a wholly-owned subsidiary of Kremlin Holdings.</span>
If this is what I'm thinking then it's like Japan's history. Where Japan was basically run by feudal lords and their loyal clans. until Japan started to becomes westernized. It's affects where a civil war between the samurai fighting for the old ways and the new Japan military who were fighting for railroads and a new age that would disgrace the samurai's life style.
Challenges of living in Hoovervilles - The woman has no running water. The woman has to complete chores like washing and cooking without having access to a kitchen.
Hoovervilles were not pleasant places. The shacks were small, poorly constructed, and lacked bathrooms. They weren't very warm in the winter and didn't always keep the rain out. The towns' sanitary conditions were deplorable, and many residents lacked access to safe drinking water. A "Hooverville" was a slum areas town built by the poors in the USA during the Great Depression. They have all been named after Herbert Hoover, the President of the United States at the time of the Great Depression and widely blamed for its onset. Charles Michelson coined the phrase.
