Not a novel.
Finally a novel. Horror, not fantasy, but, at least it's a novel form. You would have better choices than Dracula, but, ok.
Tarzan the Terrible, 1921.
Not a novel. If you had been paying attention, we have been discussing novel form, not short story or oral tales or plays.

No need to go back any particular length of time (The Lensman stories date from the 1950s BTW). Stories of the fantastic, written for no reason other than entertain, and not needing to be pigeon-holed into Science Fiction or Fantasy, have been around since the start and still being written now, as Star Wars proves. Trying to stick things into boxes is a stupid exercise at the best of times, trying to do it on the basis of how it addresses "moral issues" is snobbery.
Nope. It's called academia. I get that you don't like the genres, and that's fine. Lots of people don't. But, that doesn't change anything. Oh, and 1950 is getting pretty close on a century btw.
But, no, it's not snobbery. It's about actually looking at the similarities between different works and realizing that genre, while porous, does allow us to have rational conversations without having to redefine words every time we have a talk.
Look, it's fairly simple. On one end, which we'll call Fantasy, you have those works that everyone will agree are fantasy. Tolkien, Howard, J. K. Rowlings, that sort of thing. And, what do those works have in common? Well, often they are morality tales, and typically, the non-real part of the story (ie. magic) is used as a plot device. The hero needs to see the Medusa, so, he gets a magic shield. Find the Horcruxes Harry! That sort of thing.
On the other end of the spectrum, we have those works that everyone will agree are SF. Heinlein, Asimov, Herbert, for the golden age stuff, Stephen Baxter, Robert Reed, James Corey (The Expanse), and others. ((Ok, I admit, I read a LOT more SF than fantasy, so, my list is a bit biased)) What do these have in common? Well, often they are about what it means to be human. Also, the non-real part of the story (the "science" stuff) is generally central to the theme of the story rather than something needed by the plot. Data is an android trying to be human. The idea of "sleeves" and "stacks" are central to the themes of immortality but not really a major part of the plot. Note, Altered Carbon isn't a PK Dick story.
Again, it's totally NOT about one being better than the other. But, there are very clear cut differences between the two at the extremes. Now, in between those two ends are a whole host of other stories. Where those stories fall on the spectrum is certainly up for debate. But the idea that there is no difference between SF and Fantasy is pretty easily disproven.
