Ah, yes, Timur the Lame, also known in the West as Tamerlane.
Timur briefly controlled all of Asia except for Mongol China and SE Asia and southern India.
Timur was arguably the worst genocidal maniac in history (barring Mohammed of course). While Timur's ravaged Asia for about 40 years, Mohammed's death cult continues to massacre people today.
I don't know about control of Asia though...Timur was a terror and justifiably so. Many kingdoms in Asia collapsed after battles with his muslim turko-mongol hordes. I have always thought of Timur as a great plunderer and never as a ruler.
