Back in the classic era of Tumblr, normie social justice believers would occasionally discover that underlying the desire for recognition of black historical accomplishments was a widespread Yakub-esque belief that black people were the original progenitors of all human societies

"Wait. You can't seriously mean that black people invented *literally all* genres of music?"
"When I say all I mean ALL!!"
"...do you think black people invented Peking Opera???"
"YES!!!"

Various forms and degrees of this belief were abetted by accounts such as the infamous "medievalpoc", who liked to claim that random medieval European kings were black and that there were significant populations of black people throughout medieval and early modern Europe

The notion peddled these days by the BBC and Anglosphere academics that medieval Europe was as racially diverse as 21st-century London is essentially a cleaned-up version of the old Afrocentrist belief that black people were the original inhabitants of every region in the world
