The universal principles of our civilization reject the idea that man, irrespectively of race, gender or religion, can be the property of another man or state. If this is the case in the context of ethics and laws in countries with a consolidated democracy, things were very much different in the past and they still are in certain areas in which slavery is a common phenomenon. The dissolution of several states from the former soviet space, the low standard of living in some Asian countries, as well as the lure of a wealthy life in Europe represented business opportunities for the criminals of transnational crime networks specialized in human trafficking. Clandestine migration in the European Union contributes to the change of the social environment, massive communities being constituted, mostly due to this migration. The consecrated freedoms of the European Union render it vulnerable in front of the groups of organized crime operating outside the Union, but greatly affecting it. Given these conditions, the worries of the leaders of the Union and of the Member States are to be expected, as well as the legal and organisational concerns for the prevention and control of human trafficking.
