Well since it was called 'Pyramid Girl' first and one of Liz Taylor's biggest roles was playing 'Cleopatra' (Egyptian queen/pyramids) Liz most probably was the inspiration for the initial song..
For some reason MJ changed the title (maybe it just sounded better..?) but that still makes Liz Taylor the inspiration right..?
Anyway, both Cleopatra and Liz Taylor were not black women
It has been said that Diana Ross (who is an African-American woman) was the actual inspiration behind the 'Liberian Girl' song.I respect your opinion while still maintaining my own.
But it still stands, the version of "Liberian Girl" that we know today was about African Women—and I believe them to be it's inspiration based off a few things that have only to do with the song itself.
In 1983, Michael Jackson and Diana Ross spent some time together on vacation in Liberia (the largest city of Costa Rica), and later he wrote that song for her.
Michael Jackson not only wrote 'Liberian Girl' for her, but he also erected a shrine dedicated to her in his Hayvenhurst family home.
