Hello! This was made as part of a project on the history of horsegirls, based off the game/show/manga Umamusume. For those unfamiliar, its basically just Japanese race horses, but now theyāre anime girls, with ears and a trail. Umamusume literally means āHorsegirlā in Japanese.
When I first got into the game I, like many others, asked the question: āHow did we get to the point where we are now without horses?ā I transformed that into the more accurate question āHow did humans get to where we are now with horses being sentient creatures?ā. Iām specifically writing a ābookā called āIppos ā The Historiesā, which covers all of horsegirl history from the early classical period onward.
There are a couple terms I use above that I have completely made up, that being Ippology and Bridlage.
Ippology, is the study of horsegirls, like anthropology for humans. The word comes from the byzantine word for horses (in this world, horsegirls), Ippos. The study encompasses all things horsegirl, Biology, Sociology, archology, and even linguists in a way.
Bridlage came from on of the questions I asked myself when creating this project, āIf humans owning horses in the real world was critical to human civilization, how does that translate into the Umamusume world?ā The answer was⦠slavery! Bridlage was a specific form of slavery, a āāāNiceāāā slavery. Horsegirls were treated differently than humansā slaves, just how a typically person wouldnāt attempt to emotionally and physically break down a horse, humans typically just treated horsegirls like, tools they could effectively communicate with for most of human history. This system was not only perpetuated by humans, but horsegirls as well, as part of a social order. Humans and Horsegirls would be socially segregated for centuries. Of course, this was different from civilization to civilization, and the degree of kindness and autonomy given to horsegirls varied. But in general, the concept was still the same, a horsegirl would belong to a human. This would change over the centuries, with gradual rights and freedoms granted to horsegirls, with the beginning of end of the institution occurring in 1865, when the United States outlawed Bridlage altogether as part of the 13thĀ amendment. Other American and European countries following suit soon after. The last country to officially outlaw Bridlage was Denmark in 2005, due to a technicality in Greenland although it had not been practiced there for quite some time. Of course, the effects of centuries of slavery on an entire species has seriously effected horsegirls and humans, and itās scars are still felt in the modern dayā¦
ANYWAYS I hope you enjoyed this map, I am happy to answer any questions, aka make up more lore based on the questions people ask me. I made all this up, and is not a reflection of any actual ethnicities or cultures. This map was inspired byĀ u/ayendea1125ās map āEthnic Composition of the United States by Survey (2026)ā andĀ u/Nightjasianās map āUma Musume (Horse-girl) Anthropology Basisā.
