Gudalur is very beautiful place located in the western Ghats region. Different race and community people are living together without any clash. They are united by doing agriculture activities. So the local festivals are based on the monsoon and paddy harvesting seasons. Migrant settlers from the Mysore region of Karnataka who left due to political instability from the region during the 1760s to the 1790s started arriving in hordes and started clearing forests and tilling the land. During the British period, after the enactment of the Criminal Tribes Act, several settlements were created by the government and members belonging to the notified communities were uprooted from their original habitations and settled here. The British officers posted in the area started regularizing land holdings based on good faith and track record.
