In the second half of the 19th century, prostitution, sex trafficking, and sexual slavery became widespread in Warsaw.[12] These activities were mostly dominated by the Jewish underworld, and their existence caused much tension and controversy within Warsaw's Polish-Jewish community.[12] While in Congress Poland and Warsaw, overall, 72.7% of prostitutes were Catholic and 21.36% were Jewish, in Warsaw the proportion of Jewish prostitutes was much higher. In 1874 two-thirds of all registered prostitutes in Warsaw were Jewish.[13] In 1889 around 75% of all brothels in Warsaw were run by Jews.[14][6]
