Looking at the history and history-of tags, it is hard to tell which questions fall into the history-of tag, without also falling into the history tag. What questions would fall into history-of, but not history? If there are none, should we merge the two tags and synonymise them?
The history tag was only used on one question, which I've now retagged history-of, thus essentially accomplishing a merge. There's no point in synonymising these two tags, since typing
history into the tag box will autocomplete to history-of anyway.
How about history-of-literature instead?
This tag will show up in autocomplete for either
history-of, and it has a clearer name to avoid confusion with historical-context. We need to be careful with "history", since it could refer either to history of literature (themes, ideas, etc.) or to history of the real world outside of literature as it relates to literary works. Using history-of-literature and historical-context separately would solve this issue.
EDIT: I've now edited all the history-of questions to history-of-literature and made a new tag wiki.
