Control of the occupied territory
Until the 1950s the Baltic States were closed territories and the foreigners were not allowed to visit them. The relations that started to be developed with the West in the 1950s made it necessary to adopt certain control measures. The Iron Curtain enabled the KGB to control society and its relations with the people living in other countries, as well as movement of people (migration, emigration, tourism). Control of the territory (both inside and outside the country) was one of the most important elements of maintaining the Soviet system, which was safeguarded by both political and public, as well as such repressive structures as the KGB, the Ministry of the Interior, the army. Particular attention was directed to the Baltic States on account of their exceptional situation, the border with the West, because the Baltic States were occupied, intense activities carried out by the Diasporas and their relations with the local population. The KGB developed a certain territory control system, which enabled it to control as large as possible territory of the country and a part of people moving through it. The most significant elements of prohibition survived until the very collapse of the Soviet system in the Baltic States.
