miscegenation

Origin

Blend of Latin miscēre (“mix”) + Latin genus (“race”) + -ation. Coined by American journalist David Goodman Croly in 1864 and first used in an anonymous pamphlet he coauthored, which claimed to be written by a person who believed in the inherent unity of all racial groups, that marriage between blacks and whites would create a better race, and that the American Civil War was a fight for the latter idea. Later, it was exposed that the pretext of the pamphlet was false and that it had actually been written by a group which hoped to inflame anger, particularly against then-US President Abraham Lincoln who was up for reelection. Replaced previous amalgamation, from metallurgy.
