determined by race"; the same dictionary termed racism a synonym of racialism: "belief in the superiority of a particular race". By the end of World War II, racism had acquired the same supremacist connotations formerly associated with racialism: racism by then implied racial discrimination, racial supremacism, and a harmful intent. The term "race hatred" had also been used by sociologist Frederick Hertz in the late 1920s. As its history indicates, the popular use of the word racism is relatively recent. The word came into widespread usage in the Western world in the 1930s, when it was used to describe the social and political ideology of Nazism, which treated "race" as a naturally given political unit. It is commonly agreed that racism existed before the coinage of the word, but there is not a wide agreement on a single definition of what racism is and what it is not. Today, some scholars of racism prefer to use the concept in the plural racisms, in order to emphasize its many different forms that do not easily fall under a single definition. They also argue that different forms of racism have characterized different historical periods and geographical areas. Garner (2009: p. 11) summarizes different existing definitions of racism and identifies three common elements contained in those definitions of racism. First, a historical, hierarchical power relationship between groups; second, a set of ideas (an ideology) about racial differences; and, third, discriminatory actions (practices). Legal Though many countries around the globe have passed laws related to race and discrimination, the first significant international human rights instrument developed by the United Nations (UN) was the Universal Declaration of Human Rights (UDHR), which was adopted by the United Nations General Assembly in 1948. The UDHR recognizes that if people are to be treated with dignity, they require economic rights, social rights including education, and the rights to cultural and political participation and civil liberty. It further states that everyone is entitled to these rights "without distinction of any kind, such as race, colour, sex, language, religion, political or other opinion, national or social origin, property, birth or other status". The UN does not define "racism"; however, it does define "racial discrimination". According to the 1965 UN International Convention on the Elimination of All Forms of Racial Discrimination, The term "racial discrimination" shall mean any distinction, exclusion, restriction, or preference based on race, colour, descent, or national or
