The fort served as a British tax storage facility for Kongu Nadu, a region comprising the districts of Salem, Erode, Coimbatore, Tiruppur, Namakkal, Karur and Dindukal.

It was an important military base for Tipu Sultan and later for the British East India Company.

The rule of the Delhi Sultanate lasted for half a century before Pandya chieftains reasserted their independence.

A son of Vijaya Raghava induced the Bijapur Sultan to help him get back the Thanjavur throne.

In 1675, the Sultan of Bijapur sent a force commanded by the Maratha general Venkoji (alias Ekoji) to recapture the kingdom from the new invader.

He did not, however, place his protégée on the throne as instructed by the Bijapur Sultan, but seized the kingdom and made himself king.

During this period Chettiar community helped the Thanjavur kingdom to mobilise money to fight against invaders.
