In 1766, it joined the insurrectiont led by the polegar of Kollamkondan after victories over the Anglo-Nawabi forces helped the revolt spread to other polygars.

That same year, General Donald Campbell began a systematic campaign, taking the forts of the major confederates one by one, including Singampati.

Anxious over Hyder Ali’s activities, however, Campbell settled the polegars’ revenue accounts and restored them to their possessions in 1767.

The palaiyam, which had been under the company's administration since 1798, was restored to its former chief, Polygar 'Nallakutti Thevar, in 1801, at the conclusion of the Second Polegar War; it survived into the 19th century as a zamindari.

The estates, road & the settlements in the Manjolai area are managed by Singampatti Groups and The Bombay Burmah Trading Corporation Ltd.
