Kannuj was an imp. state which was the pivot of struggle for all the kings of northeast India.

A struggle arose among the nobles which came to be known as tripartite struggle. In this struggle prithiharas became victories

Tripartite Struggle:

The tripartite struggle refers to a series of battles fought among the three major powers in medieval India - the Pratihara Empire, the Rashtrakuta Empire, and the Pala Empire. This struggle lasted for over two centuries, from the 8th to the 10th century AD, and had significant implications for the political landscape of the Indian subcontinent.

Pratihara Empire:
- The Pratiharas were a powerful dynasty that ruled over present-day northern India from their capital at Kannauj.
- They were known for their military prowess and were able to expand their territory through conquests and strategic alliances.
- The Pratiharas faced constant threats from both the Rashtrakutas in the south and the Palas in the east.

Rashtrakuta Empire:
- The Rashtrakutas were a dominant force in the Deccan region of India, with their capital at Manyakheta (present-day Karnataka).
- They were known for their architectural achievements, particularly their rock-cut temples at Ellora.
- The Rashtrakutas sought to expand their empire northwards, leading to conflicts with the Pratiharas.

Pala Empire:
- The Palas were a powerful dynasty that ruled over present-day Bengal and Bihar, with their capital at Pataliputra.
- They were known for their patronage of Buddhism and their contributions to the spread of Indian culture.
- The Palas also sought to expand their influence westwards, coming into conflict with both the Pratiharas and the Rashtrakutas.

Implications:
- The tripartite struggle weakened all three empires, making them vulnerable to external invasions.
- It also led to a power vacuum in northern India, paving the way for the rise of new dynasties such as the Cholas and the Ghaznavids.
- Despite the intense rivalry among these empires, they also engaged in cultural exchanges, leading to the enrichment of art, architecture, and literature in medieval India.
