Karur is one of the oldest towns of Tamil Nadu and has played a very significant role in the history and culture of the Tamils. Its history dates back over 2000 years, and was a flourishing trading center from the early Sangam days. In the ancient and medieval times, the area was ruled by Cheras, Gangas and Cholas.The Pasupatheesvarar Temple in Karur was built by the Chola kings in the 7th century. Later the Nayakars followed by Tipu Sultan also ruled Karur. The British added Karur to their possessions after destroying the Karur Fort during the war against Tipu Sultan in 1783. There is a memorial at Rayanur dedicated to the warriors who lost their lives in the fight against the British in the Anglo-Mysore Wars.
