>>43262181If you want low magic then 5e D&D is out. If you don't want the game to be super lethal then Warhammer Fantasy is also out. Fantasy Craft is basically a better version of
3.PF, but it's very highly-regarded on /tg/ and you can easily remove all magic from it so that shouldn't be a problem. It has rules for time periods all the way from the stone age to the Industrial Age, so go with that if your players are familiar with D&D or Pathfinder.
If you want something that isn't D&D then Runequest 6 would probably work fine. I've never actually played it, but I've heard it's quite good and it also doesn't have to have magic by default. It's based on Chaosium's Basic Roleplaying, the same system used by Call of Cthulhu.
