I like having a detailed and accurate timeline, but it's more for my sake than my players. Something to reference as I go about building adventures and campaigns. I try to keep the events relevant to how the modern world acquired its current shape, or as possible plot hooks for adventures. An obscure war 900 years ago that has no bearing on the current political landscape doesn't belong in my timeline. If that war produced an artifact MacGuffin that's going to make an appearance in the current campaign, it belongs.
I make all my setting documents available to my players, but I neither require nor expect them to read it. However, I always do a quick overview of the last 50 years because the world underwent a pretty major catastrophe, and the campaigns I've run have all taken place in the aftermath of that. The age of PCs is a very salient point, with older characters having lived in a world that was much safer, wealthier, and integrated with magic than the present day, and I think it's important information when conceptualizing a character.

Anyway, it sounds like you've got enough ancient history stuff to ground your modern era stuff. If I were a player at your table, I would probably want to know more about the modern era, the "normal" history as you call it. However, don't be surprised if your players don't give a whit about all your writing. Most of mine don't, and that's fine. Like I said, my setting documents are for me.
