Nilakkottai (also spelled as Nilakottai) is a town in the Dindigul district of the Indian state of Tamil Nadu.

In these lands, he built a mud fort Nilakkottai in 1366 A.D with permission from lord vishnu Devaraya Raya.

Makkala ruled this fort for 12 years until he was succeeded by his son, Kulappa Nayaka.

Nagama Nayakkar defeated the Chola ruler and took Madurai, but suddenly withdrew his allegiance and declined to help the Pandya king, usurping the throne.

Droughts prevented agricultural success in Nilakotttai, so Kulappa Nayakar was unable to pay his tribute to the British government.

The conflict came to a head in 1797 when, after sending his family to Dobinayanakanur, the Polegar gathered forces in Kallarnadu, joined the revolt, and tried unsuccessfully to expel the British garrison from his fort.
