Today, the mixes among races and ethnicities are diverse, so it is considered preferable to use the term "mixed-race" or simply "mixed" (mezcla).In Portuguese-speaking Latin America (i.e., Brazil), a milder form of caste system existed, although it also provided for legal and social discrimination among individuals belonging to different races, since slavery for blacks existed until the late 19th century.
The term's historical use in contexts that typically implied disapproval is also a reason why more unambiguously neutral terms such as interracial, interethnic or cross-cultural are more common in contemporary usage.
In Spanish, Portuguese, and French, the words used to describe the mixing of races are mestizaje, mestiçagem and métissage.

It was organised by Peruvian artist and activist Richard Torres who acted as a priest for the pro-tree weddings.
The word was coined in an anonymous propaganda pamphlet published in New York City in December 1863, during the American Civil War.
The pamphlet was entitled Miscegenation: The Theory of the Blending of the Races, Applied to the American White Man and Negro.
It purported to advocate the intermarriage of whites and blacks until they were indistinguishably mixed, as a desirable goal, and further asserted that this was the goal of the Republican Party.
The pamphlet was a hoax, concocted by Democrats, to discredit the Republicans by imputing to them what were then radical views that offended against the attitudes of the vast majority of whites, including those who opposed slavery.
There was already much opposition to the war effort.
The pamphlet and variations on it were reprinted widely in both the north and south by Democrats and Confederates.
Thus the Comte de Montlosier, in exile during the French Revolution, equated class difference in 18th-century France with racial difference. in 1863, and the etymology of the word is tied up with political conflicts during the American Civil War over the abolition of slavery and over the racial segregation of African-Americans.
