ENUnlike in the USSR and even in the other Baltic republics in which initially only the inhabitants of the “regime” territories received identity documents, the universal issuance of passports in the Lithuanian SSR was carried out in 1944–1946. The hurried introduction of the passport regime had to help the repressive institutions fight against the anti-Soviet underground, to unmask the illegally living people hiding from mobilization as well as repressions. The passport system created favorable conditions for this: making use of the certificates issued by the institutions of local governments, the militia began to collect individual data about the place of residence, occupation, previous conviction, etc. of individuals, in the cities and rural localities frequent campaigns of checking document were organized. Moreover, the majority of the population in 1944–1953 did not receive passports, but temporary (one-year duration) documents and were forced to renew the data about themselves every year. The work with the personal identity documents, their card files was quite complicated, demanded intellectual forces, which the poorly educated militia and security officials lacked, both departments coordinated cooperation with difficulty. There were frequent violations of the passport system, counterfeit documents were wide spread. Nevertheless, even if the militia did not use the full potential foreseen in the “Passport Provisions” for the functioning of the Soviet passport system, it was a very effective measure for controlling the population.
