What cultures do you wish more fantasy took inspiration from?

Okay, so I’ve started a project that I’m assuming could potentially take me the rest of my life, because it is A LOT, but I’m asking for y’all’s help anyway.

Basically, I’m doing a world with 18 countries, but each country is inspired by FOUR real-world cultures, preferably each one being from vastly different regions of our world. This way, while each country will feel vaguely familiar to an outside observer, it will primarily feel like its own culture, rather than just a stand-in for a single real-world culture.

(For contrast, most fantasy tends to be inspired by Western Europe and little else, and if they do incorporate another culture, it’s essentially another continent turned into a flat caricature).

So, if you’ve done the math like I have, 18 countries with four inspirations each means I’ll need 72 inspirations total. Thus, while I’m in the brainstorming period, I want to ask y’all;

What cultures (current or historical) do you WISH you saw more fantasy take inspiration from, but end up not seeing very often?
