Which empire was known for its nomadic lifestyle and expansion across Central Asia?

The Mongol Empire is recognized for its nomadic roots and significant territorial expansion across Central Asia. Originating from the steppes of Mongolia, the Mongols were traditionally a nomadic society that relied on herding and horseback riding. This lifestyle not only defined their culture but also contributed to their military tactics, allowing them to move swiftly and engage in warfare effectively.

Under the leadership of Genghis Khan in the early 13th century, the Mongol Empire expanded rapidly, ultimately becoming the largest contiguous land empire in history. They successfully united the Mongol tribes and launched campaigns that led to the conquest of vast territories, including parts of China, Russia, and the Middle East. This expansion was characterized by their use of mobility, incorporating a highly organized cavalry that utilized the vast grasslands of Central Asia for logistical advantage.

The Safavid Empire, established in Persia, was similarly based on settled governance
