The race of the future is a theoretical composite race which will result from the ongoing racial admixture. Richard von Coudenhove-Kalergi in 1925 in Practical Idealism predicted: "The man of the future will be of mixed race. Today's races and classes will gradually disappear owing to the vanishing of space, time, and prejudice. The Eurasian-Negroid race of the future will replace the diversity of peoples with a diversity of individuals." Kalergi's statement has subsequently been utilized as a part of the white-supremacist Kalergi Plan conspiracy theory.
