National Security Services
Generally, we distinguish between two types of national security services. One is the internal intelligence service (or counterintelligence), which collects and manages information about a country’s internal security. Its task is to protect the state, the territory, and society from foreign interference (subversion, espionage, political violence).
Latvia had lost its statehood de facto in the years of the Soviet occupation. Its security structures during the Soviet period were established by an external, hostile force. Therefore, we cannot talk about the ‘transformation’ of Latvian security services in 1990 and 1991, but rather about ‘demolition’ and ‘rebuilding anew.’
The following article describes the transformation process of the State Security (hereinafter StB)  in the Slovak Republic, which began after the “Velvet Revolution” in November 1989. Following the “Velvet Revolution,” a democratization process was initiated in all areas of social life, including political, economic, social, as well as changes in the security services.
In 1989, Czechoslovakia was an integral part of the Soviet bloc, a member of the Warsaw Pact and, although there were significant changes in the Soviet Union weakening its power over its satellites, the then top Czechoslovak officials still kept their traditional, very rigid positions.
