Historical means the the topic must be about something that happened at least 20 years ago.

Text or self posts should have a clear question or observation. No 1 or 2 word titles

No blog or vlog spam.Feel free to post links to your own content (within reason). But if that's all you ever post, and/or — you submit the same post or video to multiple subreddits - you might just be a spammer. A widely used rule of thumb is the 9:1 ratio, i.e. only 1 out of every 10 of your submissions should be your own content.

Link directly to the article. Do not use text posts for links, do not link to another subreddit, do not use link shorteners or any other type of link that does not send the user directly to the piece.

Don't editorialise link submission titles with your own opinion. e.g. no "TIL" , "Is this true?" or "this is shocking"

No incivility, trolling, racism, homophobia, or sexism. Be nice to each other. Robust opinions are fine, slurs and insults are not.

No urban explorer posts. Posts or videos on old or abandoned places must be about buildings or sites that are at least 20 years old, and the article or video mostly about the history of the place, not just wandering around looking at broken stuff.
