Rajadhiraja Chola I vs Wang Shichong

Rajadhiraja Chola I was crowned as co-regent alongside his father Rajendra Chola I, a common practice in the Chola dynasty. This ensured a smooth succession and allowed him to gain administrative and military experience before becoming sole ruler.

Rajadhiraja Chola I led several campaigns into the Deccan plateau against the Western Chalukyas, aiming to expand Chola influence northward. These campaigns resulted in temporary gains but failed to achieve lasting territorial conquests.

Rajadhiraja Chola I fought the Battle of Koppam against the Western Chalukya king Someshvara I. The battle was indecisive, with both sides claiming victory, but it marked the beginning of a prolonged conflict between the Cholas and Chalukyas.

Rajadhiraja Chola I was killed while fighting on an elephant at the Battle of Kudal Sangamam against the Western Chalukya king Someshvara I. His death on the battlefield was a rare event for a Chola monarch and led to the accession of his brother Rajendra II.

Wang Shichong, a Sui general, staged a coup in Luoyang, killing the Sui regent and declaring himself emperor of the short-lived Zheng dynasty. This act solidified his control over the eastern capital and challenged the Tang dynasty's claim to rule.

Wang Shichong's forces were decisively defeated by Li Shimin's Tang army at Hulao Pass. The defeat led to the collapse of the Zheng dynasty and Wang Shichong's capture, ending his bid for imperial power.

After his capture at Hulao, Wang Shichong was executed by the Tang dynasty. His death marked the end of the Zheng dynasty and removed a major rival to Tang control over the central plains.
