The objective of this paper is to present some of the most relevant moments which have influenced the evolution of political correctness and to reveal the connection between these moments. The phenomenon appeared in America as an attempt to help certain categories of people which had been previously misrepresented or overlooked. In the 60’s it became part of the ideology of the American New Left, who helped it spread to the universities, inspired by cultural Marxism, German philosophy and postmodernism. Globalization has brought political correctness to Europe, but the Western countries have been more receptive to it than Eastern ones, which have experienced communism and could not help noticing the similarities.
