Sovietization (Russian: Советизация) is the adoption of a political system based on the model of soviets (workers' councils) or the adoption of a way of life, mentality, and culture modelled after the Soviet Union. This often included adopting Cyrillic script, and sometimes also the Russian language.
A notable wave of Sovietization (in the second meaning) occurred in Mongolia and later during and after World War II in Central Europe (Czechoslovakia, East Germany, Hungary, Poland etc.). In a broad sense, this included (voluntary and involuntary) adoption of Soviet-like institutions, laws, customs, traditions and the Soviet way of life, both on a national level and in smaller communities. This was usually promoted and sped up by propaganda aimed at creating a common way of life in all states within the Soviet sphere of influence. In many cases, Sovietization was also accompanied by forced resettlement of large categories of "class enemies" (kulaks, or osadniks, for instance) to the Gulag labor camps and exile settlements.
In a narrow sense, the term Sovietization is often applied to mental and social changes within the population of the Soviet Union and its satellites which led to creation of the new Soviet man (according to its supporters) or Homo Sovieticus (according to its critics).
