Dhana Nanda vs Zhizhi Chanyu

Dhana Nanda was known for amassing enormous wealth through heavy taxation and conquest. His treasury was said to contain vast amounts of gold and silver, which later funded Chandragupta's campaigns after being seized.

During Alexander the Great's invasion of the Indus Valley, Dhana Nanda's large army, reportedly numbering 200,000 infantry and 20,000 cavalry, deterred Alexander from advancing into the Ganges plain, contributing to his army's mutiny.

Dhana Nanda, the last ruler of the Nanda dynasty, was overthrown by Chandragupta Maurya with the guidance of Chanakya. The coup ended Nanda rule and established the Maurya Empire, one of ancient India's largest empires.

Zhizhi and his brother Huhanye fought for control of the Xiongnu confederation. Zhizhi defeated Huhanye initially, but Huhanye submitted to the Han dynasty, gaining their support. Zhizhi then moved west, splitting the Xiongnu.

After moving west, Zhizhi Chanyu attacked the Wusun people and allied with the Kangju. He established a base in the Talas River valley, raiding neighboring tribes and disrupting trade routes, which provoked Han intervention.

Zhizhi Chanyu, having moved west into Central Asia, was attacked by a Han Chinese expeditionary force led by Chen Tang and Gan Yanshou. His fortified city was stormed, and Zhizhi was killed. This battle marked the furthest westward expansion of Han military power and ended Zhizhi's threat to the Han.
