Ayudha dynasty

The Ayudha dynasty was the short-lived ruling dynasty of the Kingdom of Kannauj from the late 8th to the early 9th century CE. It was established when Vajrayudha deposed the Varmans and started ruling over Kannauj.

History
The successors of Yashovarman, the powerful king of Kannauj, were all weak rulers who did not demonstrate the skills to run and defend the kingdom. Kannauj was taken over by Ayudhas, probably during the reign of Bhoja of Kannauj (not to be confused with Mihira Bhoja or Bhoja).

Vajrayudha
Vajrayudha, who ascended to the throne in 770 CE, was the first ruler of the dynasty.

He was probably defeated by the Karkota king of Kashmir, Jayapida. But if Jayapida carried out this campaign in the later years of his career, however the defeated king of Kannauj he defeated must instead have been Vajrayudha's successor, Indrayudha.

Indrayudha
Indrayudha succeeded his father Vajrayudha in 783. He was defeated by the powerful Rashtrakuta king Dhruva Dharavarsha, and the powerful king of the Palas, Dharmapala. Instead of annexing his territory, Dharmapala made Chakrayudha, his protégé, king of Kannauj as his vassal, and this was approved by the rulers of all the neighbouring territories. But then the two brothers, Indrayudha and Chakrayudha, started fighting for the important city of Kannauj.

Chakrayudha
When Dharmapala defeated Indrayudha, he appointed Indrayudha's brother, Chakrayudha, his protégé as the king of Kannauj, but as a vassal under Dharmapala. This arrangement was approved by the rulers of all the neighbouring territories. But then both the brothers, Indrayudha and Chakrayudha started fighting for the important city of Kannauj. Then the Rashtrakuta emperor Govinda III invaded the north and defeated and gained the submission of both Dharmapala and Chakrayudha.

Decline
The invasion of Govinda III that defeated Chakrayudha and his overlord Dharmapala caused in anarchy and confusion in the region. The population was harassed by these invasions. Then the king of the Gurjara-Pratiharas, Nagabhata II, took advantage of the situation, invaded Kannauj, defeated Chakrayudha, and then made Kannauj his capital. This marked the end of the Ayudhas.
