This paper represents a socio-political process synthesis concerning integration in the US, as one of the first countries to experiment multicultural practices and realize a multiethnic consciousness, for overcoming the social discrimination. It explains how, in more than a century of social and political activism, has almost been impossible to eradicate completely the racism stronghold, creating a civic consciousness. At this point, can we think about racism phenomenon as a biological matter? Actually, as explained by R. Siebert (Siebert, 2001), the racism has grown up in the collective imaginary as something that belongs to the humans naturally. It is just a historical process of Modernity, appeared in the west territories. The US, as this paper highlights, are an example of how the racism is connected to the historical events.
