While Afro-Mexican may not be the most common term, there have been communities in Mexico with populations of African descent since North America was colonised. This book, Black Mexico: Race and Society from Colonial to Modern Times by Ben Vinson III and Matthew Restall, collects many documents and interviews to create a series of chapters illustrating first-hand accounts across the timeline of this particular aspect of race in Mexican culture has changed and existed. It’s an interesting look into the perceptions of ethnicity and racial identity.
