Answer: The Ring-Fence policy was an ideology that was enacted by Warren Hasting and it involved defending their neighbours’ frontiers in order to safeguard their own territories.
This policy was named after the term “ring-fencing.” The war that the East India Company fought against the Marathas and the Mysore Kingdom was a reflection of this fact.
The East India Company would dispatch soldiers to bolster the defence of its allies, and the rulers of the respective kingdoms would be responsible for paying the expenses associated with the soldiers’ upkeep.
This would ensure that the local ruler would continue to rely on the East India Company for its military protection.
