In Canada, however, the Métis, who also have partly Amerindian and partly white, often French-Canadian, ancestry, have identified as an ethnic group and are a constitutionally recognized aboriginal people.
These non-English terms for "race-mixing" are not considered as offensive as "miscegenation", although they have historically been tied to the caste system (Casta) that was established during the colonial era in Spanish-speaking Latin America.
Some groups in South America, however, consider the use of the word mestizo offensive because it was used during the times of the colony to refer specifically to the mixing between the conquistadores and the indigenous people.
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.
In the United States, miscegenation has referred primarily to the intermarriage between whites and non-whites, especially blacks.
Before the publication of Miscegenation, the word amalgamation, borrowed from metallurgy, had been in use as a general term for ethnic and racial intermixing.Such ideas are pursued in greater depth in Montagu's books on the subject. states, as well as laws in South Africa, also banned sexual relations between such individuals.in Nazi Germany (the Nuremberg Laws) from 1935 until 1945, and in South Africa during the early part of the Apartheid era (1949–1985). In the United States, various state laws prohibited marriages between whites and blacks, and in many states they also prohibited marriages between whites and Native Americans or Asians.Intermarriage occurred significantly from the very first settlements, with their descendants achieving high rank in government and society.To this day, there are controversies if Brazilian class system would be drawn mostly around socio-economic lines, not racial ones (in a manner similar to other former Portuguese colonies).There was already much opposition to the war effort.
