The relationship between the real world and Tolkien's Eä, or the relationship between the real-world history and the stories of the legendarium, is a matter of debate. Or rather, several. As the legendarium encompasses everything from the creation of the described world to its end, the debates include a very wide variety of subjects. The forums on the world wide web maintained by fans, tolkienists or local Tolkien societies are a place for the discussions on these subjects, but there exists also private blogs and newspapers in which the subjects maybe developed and published. Full list of discussions about the relationship is likely impossible to make, so here we could just list some of the common themes of these.
