History & Growth

Name "rajapalayam" is
derived from the word "rajas" tamil synonym for raja and palayam in
tamil means a "cantonment on fort". Thus rajapalayam means raja's fort.
rajapalayam is inhabited by people who came from the old vijayanagaram
state. One chinna raja, a lineage decedent of the king of vijayanagar
belonged to pasumpatti migrated to the south along with his followers
and settled at kilarajakularaman at the first instance and then moved
their settlements to palayapalayam in 1483 a.d. When vijayanagaram rule
was established in madurai, the descendents of the original emigrants
were said to have served under the chokkanatha nayak, king of madurai
(1659 -1682) who has recorded his appreciation of the service rendered
by chinna raja and his four sons and has granted sasanam. Either after
the battle of talaikotta (1565) or on the eve of the same battle more
rajas migrated to the south from the vijayanagar empire. They settled
in pudupalayam, western portion of rajapalayam
municipality

chokkanatha nayak (1706 -1732).rajapalayam was constituted as a united
board in the year 1885. It became a panchayat board in the year 1930.
