Historical Accuracy: The combined definitions of the words "Historical" and "Accuracy".
The term "Historical Accuracy" is defined as concerning history or past events, in the state of being correct or precise.
If a piece of entertainment claims to be historically accurate and yet it does not line up with historical documents, photographs, or first-hand accounts, then it is not considered historically accurate, but historical fiction, alternate history, or something else.

Historical accuracy is typically used in reference to forms of entertainment like books, movies, and video games, all of which sometimes base themselves in specific eras of world history. Historical accuracy in these forms of entertainment exists at varying levels, typically depending on the story's setting, the specific genre, and the expectations that consumers have for it. Sometimes, the historical accuracy of a specific piece of entertainment can be increased or decreased, based on the creator injecting their political and or religious beliefs into the story.

Additionally, sometimes the terms "historical accuracy" and "historical authenticity" are politicized and used to suggest closeted bigotry and or sexism, but this idea is incorrect. With few exceptions, those that desire historical accuracy or authenticity in their entertainment only want it as it is defined. There is no secret or nefarious definition of historical accuracy, for the majority of consumers.

Study of history will be a fluid and all-encompassing creative work.

Term used to define Black people

Abbreviated as HWC. A term coined to reflect the changing environments of many colleges and universities that either formerly or currently only accept cisgender women. Referring to something as an HWC can either mean that it's now co-ed, that their policies regarding gender non-conforming and nonbinary individuals are more relaxed, or as a way to recognize the fact that not everyone who attends a college branded as "a women's college" is necessarily a woman.
