Amalgamation is a now largely archaic term for the
intermarriage and interbreeding of different ethnicities or "races". In the English-speaking world, the term has been in use into the twentieth century. In the United States, it was partly replaced after 1863 by the term
miscegenation. While the term amalgamation could refer to the interbreeding of different white as well as non-white ethnicities, the term miscegenation was used to refer specifically to the interbreeding of
whites and non-whites, especially
African-Americans.
