In many parts of the Americas today, there are still people of African Negritic racial backgrounds who continue to exist either blended into the larger African-Americas population or are parts of separate, indigenous groups living on their own lands with their own unique culture and languages.

One such example is the Washitaw Nation who owned about one million square miles of the former Louisiana Territories, (see www.Hotep.org), but who now own only about 70,000 acres of all their former territory. The regaining of their lands from the U.S. was a long process which concluded partially in 1991, when they won the right to their lands in a U.S. court.

The Black Californian broke up as a nation during the late 1800’s after many years of war with the Spanish invaders of the South West, with Mexico and with the U.S. They blended into the Black population of California and their descendants still exist among the millions of Black Californians of today. 

The Black Caribs or Garifunas of the Caribbean Islands and Central America fought with the English and Spanish from the late fifteen hundreds up to 1797, when the British sued for peace. The Garifuna were expelled from their islands but they prospered in Central America where hundreds of thousands live along the coasts today.

The Afro-Darienite is a significant group of pre-historic, pre-columbian Blacks who existed in South America and Central America. These Blacks were the Africans that the Spanish first saw during their exploration of the narrow strip of land between Columbia and Central America and who were described as “slaves of our lord” since the Spaniards and Europeans had the intention of enslaving all Blacks they found in the newly discovered lands.

The above mentioned Blacks of pre-columbian origins are not Blacks who mixed with the Mongoloid Indian population as occurred during the time of slavery. They were Blacks who were in some cases on their lands before the southward migrations of the Mongoloid Native Americans. In many cases, these Blacks had established civilizations in the Americas thousands of years ago.
