kuro-rekishi

noun · from the anime Turn A Gundam

“Dark history”: a word from a giant-robot anime that now appears in newspapers. Most people who use it have no idea.

2000s

Provenance — where it came from

In 1999, the TV anime Turn A Gundam used the term 黒歴史 (kuro-rekishi), “the Black History,” for a sealed record of ancient space wars — a past so terrible that civilization buried it and started over.

Fans of the series borrowed the term for their own buried pasts. Everyone has one: the notebook of poems, the homemade novel, the photos from a regrettable fashion phase. These are your personal kuro-rekishi — history you have sealed, and pray no one excavates.

Then the word did what few anime terms manage: it left the fandom completely. By the 2010s, politicians’ old statements, companies’ failed products, and celebrities’ early careers were all being called kuro-rekishi in mainstream media. The word now works for people who have never seen a Gundam. A term invented for fictional space wars, applied daily to real embarrassment. It is a promotion very few words ever receive.
