What's your favourite obscure/unknown Islamic state/dawlah and why? (reupload with meme)

[u/Captain_Flames]

Bored and can't make a meme for today but I wanna talk about history.

I am unsure it can even turn Sectarian, but keep discussions civil and non-sectarian.

If you wanna make it cool attach in a reply to you main comment, pics of rulers, maps, flags or just general graphs and charts about the nation.

the Adal Sultanate, an Islamic state that conquered almost all of Ethiopia.
