Can someone explain why this question is a request "for trivia or basic historical facts" and this "off topic"? I'm looking for guidance on how I might improve it since it's entirely unclear to me where any of the objections to it are coming from.
The question is worded in a manner where it can invite multiple answers. That is not in of itself a bad thing, but it seems like you were looking for a specific type of answer, and the question is not constructed to elicit specific answers. Also, as was mentioned in a previous answer to this question, it is not entirely clear what you are asking.
