The Polygar's role was to administer their Palaiyams (territories) from their fortified centres. Their chief functions were to collect taxes, maintain law and order, run the local judiciary, and maintain a battalion of troops for the king.
They served as regional military and civil administrators. In turn they were to retain 1⁄4 of the revenue collected as tax, and submit the remaining to the king's treasury. The Polygars also at times founded villages, built dams, constructed tanks and built temples. Also the rulers taxed regions according to the cultivable and fertility of the land. Often several new rainwater tanks were erected in the semi-arid tracts of western and southern Tamil Nadu.
Their armed status was also to protect the civilians from robbers and dacoits who were rampant in those regions and from invading armies which often resorted to pillaging the villages and countryside.
Main article: Polygar Wars
The Polygar Wars were a series of wars fought by a coalition of Palaiyakkarar's against the British between 1798 and 1805. The war between the British and Veerapandiya Kattabomman is often classified as the First Polygar War (1799), while the Second Polygar War (1800–1805) against the British was fought by a much bigger coalition over the whole of western Tamil Nadu headed by Dheeran Chinnamalai and Maruthu Pandiyar, brother of the Sivaganga. A final Polygar War in 1847 against the British was fought by Uyyalawada Narasimha Reddy at Kovelakuntla (Koilakuntla)
The Polygars often had artillery and stubbornly resisted the storming of their hill forts. The British columns were exposed throughout the operations to constant harassing attacks and had usually to cut their way through almost impenetrable jungles while being fired on from under cover on all sides. It took more than a year to suppress the rebellion completely.
After a long and expensive campaign the British East India Company finally defeated the rebelling Polygars, some of whom were executed while others were banished to the Andaman Islands. Of the Polygars who submitted to the British, some of them were granted Zamindari status, which had only tax collection rights and disarmed them completely.
