There is genetic and linguistic evidence that proves that the Celts were Black or African people. An examination of the language spoke by the Basque has a Niger-Congo substratum. C.J.K. Cambell-Dunn has found a Niger-Congo substratum in Basque.
The Celts were originally Black people. Ephorus (c. 405BC) claimed that the Celts were Blacks or Ethiopians.The Celts continued to be recognized as Blacks by Tacitus, who wrote about the Black Celts and Picts in 80 AD.
The original Danes or Vikings were Blacks. This is made clear in the Oseberg 8th Century Vikings on the Norway Sledge carving of the Black seafarers that populated the region at this time. It is clear from this carving that the 8th Century Vikings were different from the Blond, big bodied folk of Viking legends.
