Interesting etymology research on the "dark history" in "Mobile Suit Gundam"

There are many words that anime and game fans are accustomed to, but few people probably know the origins of some of them. For example, the word "black history" is a well-known one. Following the analysis of foreign media, we can understand how this word came about.

•The term “black history” was not created by any comedian, but actually comes from a work in the Japanese animation “Mobile Suit Gundam”, “Mobile Suit ∀ Gundam”. When it comes to this work, apart from the strange setting of the protagonist, the bearded King Gundam, even veteran fans probably wouldn’t have guessed that “black history” was actually created in this work.

•The story setting and world view of "Mobile Suit ∀ Gundam" expose the various dark secrets of the behind-the-scenes war in the first generation of "Mobile Suit Gundam", and the same is true for other areas of society. Perhaps everyone has a "dark history" that they don't want others to know, but the degree of darkness is different.
