The Kadakal Rebellion of 1938 or Kadakkal Revolt was a civil disobedience movement that happened against unfair toll collection in Kadakkal of Kollam district in the course of India's struggle. It is a unique event in the history of the princely state of Travancore. The event which started as a mass movement against excess tax or toll collection by authorities eventually culminated in the formation of a parallel administration named Kummil Pakuthi, perhaps the smallest in the world lasting for a short span of eight days. The event is also known as Kadakkal Riot Case and is recognized as an Indian independence movement by Ministry of Home Affairs (India).
