medical check-ups. Prostituting took place mainly in “pleasure flats” where the woman was operating as a “free tenant”. Each of these apartments had approximately 4-9 women. In 1940, there were 47 of such apartments registered. The majority (90%) of Tallinn prostitutes in the beginning of the 1920s were Estonians, 8% were Russians and the rest other nationalities. Thirty per cent were up to 20 years old, but the largest group was 20–25 years old (about 50%) and 26–30 years old were represented at around 15%. About 30% were born in Tallinn, 60% from elsewhere in Estonia and about 10% from abroad. Soviet period Along with Estonia's occupation by the Soviet Union, attitudes to prostitution changed drastically. Legalization of prostitution was replaced by total denial and was made criminal. For instance, Tallinn City Moral Censoring Unit and Ambulatory of STDs which had been controlling the prostitutes and their health, was now liquidated on 16 November 1940, only a few months after occupation. Prostitutes who were registered at the police were repressed as “socially alien beings” and were listed, along with thousands of other people, to be deported from Estonia in 1941.

There were three relevant paragraphs in the Criminal Law: Criminal Code of Estonian Soviet Socialist Republic (ESSR) (paragraph 200) - preparing or distributing a pornographic item; paragraph 201 - keeping a brothel; paragraph 201-3 - begging, vagrant or the parasitic lifestyle. Pimping was not considered in the Criminal Law of ESSR. In reality those paragraphs that were related to prostitution were hardly ever used. The reason was absence of prostitution as a mass phenomenon in Soviet Estonia and indifference to it from that part of the government. In Tallinn, only a type of systematically operating prostitutes existed - the so-called “foreign currency prostitutes” who were only serving foreigners. Since the KGB kept a vigilant eye on foreigners, the activities of those prostitutes were only feasible with the knowledge and control of this structure. There are some reasons to suggest that some prostitutes serving foreigners were used as informants by the KGB. Post-Soviet period Certain changes started in the mid-1980s when the first signs of private businesses emerged. That also brought along differentiation of incomes. The increase in the relations with foreigners had a great impact on the following processes. Due to
