Historical evidence confirms that the Soviet Union implemented severe travel restrictions and closed its borders to curb emigration and limit exposure to Western influence.

The analysis

The retrieved literature, particularly historical analyses of daily life and Sovietization behind the Iron Curtain (papers 3 and 11), directly supports the claim that the Soviet regime restricted travel and closed borders to control its population and prevent ideological subversion or emigration. Other papers are tangential or pertain to entirely different topics (e.g., wheat genetics, tuberculosis strains, Latin American migration).
