Nayak dynasty
During Muttu Krishnappa Nayak (1601–1609 A.D.) of Madurai Nayak dynasty reign, the Ramnadu region, due to lack of efficient leadership, crimes and robbery found frequently against pilgrims of Rameswaram through the wild jungle. Due to lack of knowledge of the Jungles, Nayak army found hard to control the robbers. Therefore, Muthu Krishnappa Nayaka (1601-1609 A.D.) laid down the foundation of the rule of the Sethupathi (watchmen of the bridge ) of Ramnadu area under Madurai Nayaks and made agreement with the locals to stop robbery. Muthu Krishnappa Nayaka appointed Sadayakka Teva as Sethupathi in 1605 A.D. to stop crimes and protect the pilgrims of Rameswaram through the wild and inhospitable region. When the power of the Nayak kings of Madurai began to decline in the late 17th century, the Raghunatha Kilavan of Ramnad asserted his independence.
