The Champakulam Boat Race in Kerala's Alappuzha district kicks off the snake boat season in Kerala every year. The race is held with great fervor on the Champakulam river, an extension of the Pamba river.
The origins of the Champakulam Boat Race dates back to four centuries making it the oldest event in this category. It is connected to the re-dedication of the deity at the Ambalappuzha Sree Krishna Swamy Temple during the reign of the Chempakasery dynasty. As the idol in the temple was found to be impure, a suitable replacement was found at the Kurichi Karikkulam Parthasarathy Temple. The king ordered his minister and the team accompanying the idol to halt at the Mappilassery family in Champakulam to avert the attack of bandits. The next morning the king himself came to Mappilassery and the idol was taken to Ambalappuzha with the accompaniment of a grand procession. The Champakulam Boat Race is held to commemorate this procession. Every year, a team from Ambalappuzha comes to Mappilassery carrying palpayasam, a famous dessert prepared at the Ambalappuzha temple. Special prayers and rituals are held before the race begins.
In 1927, the Champakulam Boat Race was inaugurated by the Travancore Diwan M E Watts. In 1952, the last king of the Travancore royal family, Chithira Thirunal Balarama Varma, came to watch the race. He instituted the Rajapramukhan Trophy. Major chundan vallams (snake boats) and boat clubs vie for this trophy every year on the Champakulam river.
