Once, the Mongol Empire had been the greatest the world had ever known. At its height, Mongolian power extended from Moscow to Guangzhou, from Baghdad and Basrah to the southern tip of Korea, yet even back then the empire was far from unified.
When the Great Khan Ogedei died, the empire was split into four -- the Il-Khanate in the Middle East, the Yuan Dynasty in China, the Golden Horde on the Russian steppe, and the Chagatai Khanate somewhere in the middle. Then the Russians pushed back the Golden Horde, and the Arabs did the same to the Il-Khanate The old governor of Anatolia, a man by the name of Hasan Buzurg got involved in a succession conflict for the Il-Khan's throne, and ended up the founder and ruler of his own new mongol statelet, starting up a Mongol dynasty which came to be called the Jalayirids.
Twenty-two years ago, the Chagatai Khanate split in half, and Timur the Lame proved you didn't need two working legs to carve out your own empire. After overrunning the eastern Il-Khanate, he moved on the Jalayirid state, and combined with a revolt of the western turkish population (Who soon called themselves the black sheep) conquered it outright.
But Timur the Lame was not immortal. His conquests mostly survived him, at the very least, but with his death they began to be rolled back... and in the city of Basrah and the surrounding desert, the Jalayirid dynasty has regained power -- of a sort.
However, it isn't much power. While he is acknowledged as the ruler of the area, Uwais the second swears two separate oaths of fealty, to two different segments of the very Turkish horde whose treason had so recently destroyed the empire of his fathers. It is a nation rife with instability, a nation where a Sunni court rules a Shi'a majority, and neither of which is all that intent on converting, and a nation where a high burden of tribute makes it impossible to so much as maintain an army -- and Basrah, even without this trouble, is hardly a rich territory! And to make matters even more dangerous, the Timurids are right next door, and there are plenty of other nations for whom Basrah would be an easy prize, perhaps even their overlords in Baghdad once they made the necessary declarations of independence... and even that would take two years.
The Khanate of Basrah, as things stand, is a nation whose position none would envy. But at the same time, there are many from the steppes of Mongolia who had set up their tents amidst the sandy, desert winds, and they weren't about to go down without a fight!
The khanate, as it stands.
