Duke Mu of Qin vs Rudradaman I

Duke Mu of Qin led campaigns against the Rong and Di barbarian tribes to the west, conquering twelve minor states and opening up 1,000 li of territory. This expansion strengthened Qin and secured its western flank.

Duke Mu formed an alliance with the state of Jin, marrying his daughter to Duke Hui of Jin. However, when Jin reneged on promises, Duke Mu attacked and defeated Jin at the Battle of Han, capturing Duke Hui.

Duke Mu supported the exiled prince Chong'er, sending troops to help him return to Jin and become Duke Wen. This act created a powerful ally but also a future rival who would challenge Qin's dominance.

Duke Mu's attempt to expand eastward was thwarted by Jin at the Battle of Yao. Qin forces were ambushed and destroyed in a narrow pass, forcing Duke Mu to abandon eastern ambitions and focus on the west.

Rudradaman I expanded the Western Kshatrapa kingdom by conquering territories in Gujarat, Malwa, and parts of Rajasthan. He brought several regions under Shaka control, strengthening their position in western India.

Rudradaman I ordered the repair of the Sudarshana Lake dam in the Kathiawar peninsula, which had been damaged by a storm. The project involved reinforcing the embankment and restoring irrigation to the region, benefiting agriculture.

Rudradaman I fought against the Satavahana king Vashishtiputra Satakarni, defeating him in battle. However, he spared his life due to a marital alliance, as Satakarni was his son-in-law.

Rudradaman I commissioned the Junagadh rock inscription, which records his repair of the Sudarshana Lake dam and details his reign. The inscription is notable for being one of the earliest long Sanskrit inscriptions in India.
