The Madura Kingdom of which Kongu formed part was divided into 72 palayams and it required the holders of palyam to offer military help to the ruler, Palayakarrar, such as the Gatti Mudalis of Omalur, Taramangalam and others. The Gatti Mudalis's rule extended east-west from Thalaivasal to Dharapuram and north-south from Omalur to Karur. After the fall of the Vijayanagara Empire, the Gatti Mudalis became the Palaiyakkarar of Omalur under Tirumalai Nayak of Madurai in 1623.
The Gatti Mudalis were the most important group during the Nayak period. They built the temple at Taramangalam which is an architectural wonder. The Salem district, the most dangerously exposed province of the Madurai Nayak Kingdom, was the seat of their power. The centre of their power however seems to have been Taramangalam, where they built a costly temple. In Salem district, they held the important strategic fort of Omalur and Attur.
In 1660, Chikka Deveraja conquered Sankagiri, Thoppur and Omalur. In 1667, the Gatti Mudalis lost Omalur to Mysore. In 1688-89, Chikka Deva Raya, the king of Mysore, felt strong enough once again to invade Baramahal and the whole district of Salem came under his control before his death in 1704.
In 1815 Omalur taluk was absorbed into Salem taluk, but was recreated in 1819. It was again absorbed by Salem taluk in 1860, and again recreated in 1910. In 1916 Omalur taluk bifurcated into Omalur and Mettur, and in 1941 Mettur Taluk was absorbed into Omalur.
