Historically, the ruler of Palakkad Palakkad Achchan, was a tributary of the Zamorin of Calicut, but had become independent before the beginning of the eighteenth century. In 1757 he sent a deputation to Haider Ali seeking help against an invasion threatened by the Zamorin. Haider Ali seized upon the opportunity to gain possession of a strategically important location such as Palghat, and from that time until 1790 the fort was continually in the hands of the Mysore Sultans or the British.
