Argentina at one time had a robust African presence because of the slaves who were brought there, but its black population was decimated by myriad factors including heavy casualties on the front lines in the War of the Triple Alliance against Paraguay in the 1860s; a yellow fever epidemic that rich, white Argentines largely escaped; and interracial offspring who, after successive generations, shed their African culture along with their features. And European immigration swelled the white population — 2.27 million Italians came between 1861 and 1914.

The demographic shift has been sharp. In 1800, on the eve of revolution with Spain, blacks made up more than a third of the country, 69,000 of a total population of 187,000, according to George Reid Andrews’s 2004 book ‘Afro-Latin America.’ In 2010, 150,000 identified themselves as Afro-Argentine, or a mere 0.365 percent of a population of 41 million people, according to the census, the first in the country’s history that counted race.

But the culture the slaves brought with them remained. And in recent years, Argentina has gone from underselling its African roots to rediscovering them, as academics, archaeologists, immigrants and a nascent civil rights movement have challenged the idea that African and Argentine are mutually exclusive terms.
