For a very long period of human history, direct physical violence used to be one of the main means of obtaining power, wealth, and prestige, as well as social control, socialization of children, and regulation of social relations. Human societies were also developing various ways of controlling and curtailing direct violence, primarily in-group violence. Major changes in the social functions of violence were associated with the development of liberal thought and liberal institutions—the free market and the democratic political system. Liberal culture and liberal mentality have delegitimized all kinds of physical violence, except in defense of human rights and freedoms. Nevertheless, the tendency to use violence, as a means of attaining political, economic, or ideological goals has not disappeared. It is being fostered by ideologies that grew out of the transformation of traditional (conservative) thought into Right-Wing Authoritarianism and/or Social Dominance Orientation, but also the transformation of liberal thought into Libertarianism (egocentric individualism). These ideologies facilitate the change of competitions and disagreements between social groups into destructive conflicts.
