Miscegenation hoax
The Miscegenation hoax, taking the form of a pamphlet subtitled The Theory of the Blending of the Races, Applied to the American White Man and Negro, was published by New York World staff in December 1863 as part of an anti-Lincoln Copperhead campaign leading up to the 1864 presidential election. The 72-page piece coined the term miscegenation (from the Latin miscere "to mix" + genus "kind") and was put together by World managing editor David Goodman Croly and reporter George Wakeman.
