The ‘Tripartite Struggle’ refers to the prolonged and intense conflict among three major powers of North India, the Gurjara-Pratiharas, the Palas, and the Rashtrakutas, for control over Kannauj, a city of strategic and symbolic importance in northern India. It is also known as the Kannauj Triangle wars and was one of the most significant political rivalries during the early medieval period in India. Read on to learn more about the Tripartite Struggle!
The Tripartite Struggle was a long-drawn-out battle for the control of Kannauj, a city in present-day Uttar Pradesh. Kannauj had strategic, political, and symbolic importance and three major powers, the Gurjara-Pratiharas, the Rashtrakutas, and the Palas, fought among themselves to take control over it during the 8th to 10th centuries.
Each of these dynasties wanted to dominate North India. Controlling Kannauj meant being acknowledged as the most powerful ruler of the time. So, this struggle wasn’t just about land, instead of about honour, supremacy, and legitimacy. The Tripartite Struggle lasted for nearly two centuries. It weakened all three dynasties in the long run and paved the way for future powers like the Cholas and later the Delhi Sultanate.
Three powerful dynasties participated in the Tripartite Struggle. Each one had strong rulers, great armies, and a desire to dominate North India.
1. Gurjara-Pratiharas
Based in the Mondor/Malwa region in western and northern India.
Founder: Nagabhatta I; Most powerful ruler: Mihira Bhoja.
They controlled areas like Rajasthan, Gujarat, and parts of Uttar Pradesh.
Known for resisting Arab invasions.
2. Palas
Based in eastern India, mainly Bengal and Bihar.
Founded by Gopala, expanded by Dharampala and Devapala.
They promoted Buddhism and were patrons of Nalanda University.
They wanted to expand westwards by capturing Kannauj.

3. Rashtrakutas
Ruled from the Deccan region, modern-day Maharashtra and Karnataka.
Founder: Dantidurga, Most famous rulers: Dhruva Dharavarsha and Govinda III.
Known for their naval strength and artistic patronage.
Wanted to expand northward.
All three dynasties fought repeatedly to hold Kannauj. However, no one could keep it for long due to constant battles and changing alliances.
The Tripartite Struggle had several underlying and immediate causes. These reasons made Kannauj the most desired city during that period.
Strategic Location: Kannauj was at the centre of the Gangetic plains. It offered access to trade routes, fertile lands, and rich resources.
Political Prestige: Controlling Kannauj was seen as a mark of supreme power in India. It was associated with Harsha’s empire, making it even more important.
Economic Benefits: The region around Kannauj was economically prosperous. It had a large population, rich agriculture, and was a trade hub.
Religious Significance: Kannauj was also a cultural and religious centre. Many rulers wanted to associate themselves with their spiritual influence.
Expansion of Territory: All three dynasties wanted to expand their empires. Capturing Kannauj would give them access to new territories.
Due to these strong causes, the Tripartite Struggle turned into a prolonged conflict. Each dynasty invaded the region multiple times and engaged in long wars to claim it.
Kannauj lies in northern India, but the reach of the dynasties extended across vast regions:
The Palas moved from Bengal in the east.
The Gurjara-Pratiharas attacked from western and central India.
The Rashtrakutas came from the Deccan region in the south.
All three dynasties met at Kannauj. A map of this struggle shows the city surrounded by powerful empires trying to take it over:
The Tripartite Struggle began in the 8th century CE and lasted until the 10th century CE (9th century CE in some sources). That means this rivalry continued for almost 200 years. The war occurred in multiple phases:
Period | Approximate Years | Key Events |
Early Phase | Late 8th century | Rise of Pratiharas and Palas; initial conflicts begin. |
Phase I | 790–810 CE | Clash between Pala king Dharmapala and Pratihara ruler Vatsaraja; Rashtrakuta intervention. |
Phase II | 810–836 CE | Dharmapala regains Kannauj; Nagabhatta II (Pratihara) and Govinda III (Rashtrakuta) intervene |
Height of Conflict | 9th–10th century | Eventually, the Gurjara-Pratiharas under Mihira Bhoja established semi-stable control but were weakened. |
The final outcome of the Tripartite Struggle didn’t favour any one dynasty entirely. Here's how the Tripartite Struggle concluded:
Political Fragmentation: The constant wars weakened all three dynasties. None of them could maintain stable rule over Kannauj for long.
Decline of Powers: The Rashtrakutas faded by the end of the 10th century, whereas the Palas lost their western influence and focused more on Bengal. The Gurjara-Pratiharas, though victorious, became politically weak due to internal rebellions.
Rise of Regional Kingdoms: After the Tripartite Struggle, many small regional kingdoms emerged. They filled the power vacuum left by the three exhausted empires.
Delhi Sultanate's Rise Made Easier: The struggle made North India politically unstable. This helped later powers like the Turkish invaders and the Delhi Sultanate to easily establish rule.
So, while the Tripartite Struggle was about winning Kannauj, in the end, it led to a decline in centralised power and the rise of new players in Indian history.
