Notable Events in History
Seithur was one of the palayams that joined Puli Thevar’s coalition in 1754-1762 (see Nerkattumseval).
When Kollamkondan rebelled in 1764, following the execution of Yusuf Khan for having betrayed the nawab, Seithur was quick to join.
In 1792, taking advantage of a border dispute, the polegar of Sivagiri invaded Seithur, killed the polygar and replaced him with a cousin. The Company intervened, however, a restored Seithur’s independence. In 1803, Tiruvanna Thevar, the 47th polegar received his sanad from the Company and became a zamindar; at the time he only held three villages.

In 1879, the zamindari of Seither had an area of 91.44 sq. m. and a population of 11,916.
Kollamkondan was merged under Seithur in the late 1800s.
