Bronze (racial classification)
Bronze race (Spanish: raza de bronce) is a term used since the early 20th century by Hispanic American writers of the indigenista and americanista schools to refer to the mestizo population that arose in the Americas with the arrival of Latin European (particularly Spanish) settlers and their intermingling with the New World's Amerindian peoples. The metaphorical referent bronze incorporates several metals, the combination of which strengthens the resulting alloy compared to each metal alone.
