Answer
Batu Khan was the grandson of Genghis Khan and the founder of the Golden Horde, a Mongol empire that dominated parts of Eastern Europe and Central Asia. After his death, the Golden Horde was divided into several khanates, including the Khanate of Azerbaijan, which ruled over parts of present-day Azerbaijan, Iran, and Georgia. The Khanate of Azerbaijan was eventually conquered by the Safavid Empire in the 16th century.
