This graduate thesis deals with the physical and ethnic differences that certain nations have experienced, how they were treated and by whom. People have seen differences between prehistory and ignoring each other. Eugenics is mentioned as an account of the disapproval and disrespect of other peoples and cultures. She and her advocates accept people who "have quality" according to their standards and charts. One of the unresolved characteristics of people was their skin color, which led to the emergence of racism in the world. After the rebellion of slaves, documents are being signed in states that forbid slavery. Modern times bring new forms of slavery - trafficking in human beings. In order to find out about human information on traditional and modern slavery, a survey was conducted involving a written data collection process - a survey. The study involved 100 respondents and included both sexes (median age 33, 26-35). The working status of the respondents was from the pupils to the retirees, but the highest percentage was employed and the VSS. The results show that people are aware of the existence of modern world slavery and are thinking of how it can be reduced to various education, security measures and punishments. Likewise, most consider that Croatia does not follow a large percentage of trafficking.
