Arani, a small town and municipality in Tiruvanamalai district of Tamil Nadu, India, literally means a place surrounded by a forest. A population of close to 65,000, Arani lies along the banks of Kamandala Naga river. Ruled by the Cholas after they defeated the Pallavas, it was a fairly peaceful period for quite some time. During the Nawab period, there was a struggle between the British, French and Nawab Hyder Ali. The victorious British captured Arni.
In the early 1930s Mahatma Gandhi had visited Arani and the Simon Movement also took place somewhat then.
