The first Battle of Panipat in 1526 was between Babur and Ibrahim Lodi. The result of the battle laid the foundation of the Mughal Empire by ending the rule of the Delhi Sultanate.
The Second Battle of Panipat in 1556 was between Akbar and Hemu; it decided in favour of the continuation of the Mughal rule.
The Third Battle of Panipat in 1761 between the Marathas and Ahmad Shah Abdali put an end to the Maratha ambition of ruling over India.
Why Panipat was a favourite battle field:
Panipat had a strategic location. One of the parties of the war generally came from the north/northwest through the Khyber Pass to get hold over Delhi, the political capital of northern India.
To move a military through rough terrains—deserts of Rajasthan or the other northern areas infested with dense forests—was very risky and difficult. On the other hand, the rulers at Delhi considered Panipat as a confrontable strategic ground and hence they preferred to take the fight there.
Its proximity to Delhi made it easier for the Indian rulers to transport weapons, military and food supplies etc., to the battleground, and still keep the capital insulated from the conflict at hand.
Panipat’s surrounding region has a flat ground which was suitable for cavalry movement—the main mode of warfare at the time.
After the construction of the Grand Trunk Road by Sher Shah Suri (1540-45), Panipat was on this route. It became easier for conquerors to find their way there.
The duration of monsoon rainfall in the region is short in comparison to other areas making it easier to fight.
