Seljaq-Ghazhadid lore, please!

Once upon a time, all my laptop could run was the late Sims Medieval, and the Watcher knows I had an absolute blast. Only thing I disliked about it was the lack of object description (usually so good at providing lore) for its catalog. One thing in particular I would love to get more info/lore on is the "Seljaq-Ghazhadid" word used to describe some vaguely Arab/Persian style objects in the game. Is it a family? A kingdom? Just a style? No one else cares, I'm sure, but I would love to know more if anyone has anything on it, better yet, I'd love to see it incorporated in an upcoming sims 4 pack or kit.
