The legends tell of a Moorish knight of the Round Table, Morien; to wind up in the legends, they were not unknown or all despised in England.
The number of Moors in 14th Century England were likely no more than a fraction of 1% of the population. There were no Asians in 14th Century England.
The notion that medieval England was a racially diverse society is a recent modern construct, propped up by bogus, pseudoscience meant to install among young people a false perception that Britain has always been multicultural.
It's simply not true. And this fakery is not happening in just Britain, but all over modern Europe.
