Appanur, as a part of the Ramnad district was under the Sethupathis during the beginning of the 17th century, then under the British Raj, before it came under the Union of India in 1947 when India received its independence.
Bhavani Shankar eventually revolted in 1720 and securing the help of the Thanjavur Maratha king Serfoji I and the Raja of Pudukkottai, invaded Vijayaraghunatha Sethupathi's seat at Aranthangi.
Muthuramalinga Sethupathi II (1841–1873) was the zamindar of Ramnad estate from 1862 to 1873.
