After the death of Harshavardhana in 647 AD, his empire fragmented. The power in his capital, Kanyakubja (Kannauj), was reportedly seized by a minister named Arunashva (also referred to as Arjuna). He imprisoned the Tang Chinese envoy Wang Xuance, which led to a punitive expedition by the Chinese.
The death of Harsha marked the end of a period of relative unity in northern India and was followed by fragmentation and the rise of various regional powers.
The Chinese accounts of Wang Xuance’s mission provide crucial information about the political situation in India immediately after Harsha’s death, specifically mentioning Arunashva’s usurpation of power.
