The racial categories that we’re familiar with developed only 200 years ago, primarily by England and Spain.

I’m not convinced. Columbus — an Italian, although he was funded by Spain at the time — landed in the ‘New World,’ in 1492. Thinking he had landed in ‘India’ he, and nearly everyone else, thereafter preceded to call the indigenous persons, ‘Indians.’

Somewhere around 1603 Will Shakespeare wrote a play about a ‘Moor’ named “Othello.”

So, if your thesis is that 200 years ago something new occurred… not so much. If, however, your thesis is that something very very old concretized into then new words and phrases (as opposed to new ideas and prejudices) that bedevil us to this day, well OK then…
