black characters in literature

[cacian]

is literature predominantly white main characters?

[EmptySeraph]

Yes, because some of the best writers were white, and a tad racist, because that was the norm back then. Also because having a black person as the main character in the 17th century would have been odd, to say the least.

[Danik 2016]

In the countries were most writers are white (but not always most people) yes. But in the countries were most or all writers are black, there is a predominance of black characters.
And one can have a situation like In US where there are black characters depicted from a
white perspective like, for example in Faulkner and from the perspective of black writers like
Ralph Ellison:"Black is better than white. But American is best of all" (quoting from memory).
