Three empires fought over one city for two centuries. The fighting itself is what wore all three of them down. This article covers the Gurjara-Pratiharas and the Tripartite Struggle for Kannauj.

Timeline
- c. 730-760 CE: Nagabhata I founds the Gurjara-Pratihara dynasty in western India and resists early Arab incursions.
- c. 790 CE: Vatsaraja defeats the Pala king Dharmapala near Prayaga, opening the Tripartite Struggle for Kannauj.
- c. 816 CE: Nagabhata II captures Kannauj and makes it the Pratihara capital.
- c. 836-885 CE: Mihira Bhoja rules. The empire reaches its widest extent under him.
- c. 890-910 CE: Mahendrapala I, Bhoja’s son, continues the empire’s peak.
- c. 916 CE: The Rashtrakuta king Indra III sacks Kannauj, marking the start of real Pratihara decline.
- 1018 CE: Mahmud of Ghazni sacks Kannauj. The Pratihara ruler Rajapala flees and is later killed by the Chandela ruler Gauda.
- 1036 CE: Jasapala, the last Gurjara-Pratihara ruler of Kannauj, dies. The dynasty formally ends.
Three Empires, One City Need to Know
- The Tripartite Struggle, also called the Kannauj Wars, was a two-century contest for control of the city of Kannauj.
- Three dynasties fought over it. The Gurjara-Pratiharas held the north and west, the Palas held Bengal in the east, and the Rashtrakutas held the Deccan in the south.
- Kannauj held imperial prestige across much of northern India. Whoever held it could claim to be its paramount power.
- No single dynasty held Kannauj for the whole two centuries. Control passed back and forth as each side’s fortunes rose and fell.
- The Gurjara-Pratiharas ultimately held Kannauj the longest, making them the struggle’s closest thing to a winner.

The Pratiharas’ Rise to Power Need to Know
- Nagabhata I founded the Gurjara-Pratihara dynasty around 730-760 CE, in what is now western India.
- He is remembered for resisting early Arab incursions into the region, before the Tripartite Struggle even began.
- Vatsaraja, a later Pratihara king, defeated the Pala ruler Dharmapala near Prayaga around 790 CE. This opened the struggle for Kannauj.
- Nagabhata II succeeded him and captured Kannauj around 816 CE, making it the Pratihara capital.
- Mihira Bhoja, ruling from around 836 to 885 CE, was the dynasty’s most celebrated king. He expanded the empire to its widest extent.
- Bhoja adopted the title Adivaraha, linking himself to Vishnu’s boar incarnation. This claim appears on his own coinage.
- His son Mahendrapala I, ruling around 890-910 CE, continued the empire’s peak and extended it further east.

Decline and the Regional Successor States Good to Know
- Real decline began around 916 CE, when the Rashtrakuta king Indra III sacked Kannauj.
- A string of weaker, less capable rulers followed, and the empire never fully recovered its earlier strength.
- In 1018 CE, Mahmud of Ghazni sacked Kannauj. The Pratihara ruler Rajapala fled rather than fight.
- The Chandela ruler Gauda, once a Pratihara feudatory, caught and killed Rajapala for abandoning the city.
- The dynasty limped on for another two decades. Jasapala, its last ruler at Kannauj, died in 1036 CE.
- As central Pratihara power faded, former feudatory states declared independence: the Chandelas, the Paramaras, and the Chahamanas (Chauhans).
- These successor states became the building blocks of the Rajput political landscape that followed in northern India.
The Wider Story Great to Know
- For the Pratiharas’ eastern rivals, see AncHist0022 — The Palas, Senas and Buddhist Learning Centres.
- For their southern rivals, see AncHist0023 — Rashtrakutas, Chalukyas, Pallavas and Cholas.
- A struggle with no clear long-term winner can still have a clear long-term loser: regional stability itself. Two centuries of contest left all three empires weaker than before it began.
- Mihira Bhoja’s religious title on his own coinage shows how ancient Indian rulers routinely blended political authority with religious legitimacy.
- The struggle’s exhaustion helped clear a path for later invasions. A divided, worn-down north India could not present unified resistance when new threats arrived.
- Three empires converging on one city for two centuries shows how a symbolic capital could matter more strategically than its immediate military or economic value.
