Ankathattu
Ankathattu is a Malayalam word identifying a four to six feet high platform constructed temporarily in Kerala, India, for the purpose of fighting duels. In Malayalam, ankam means war. The platform was constructed according to tradition and in the centre of a ground from where all people could watch the fight. This place altogether is called Anka-Kalari.
In earlier centuries in Kerala, if there was a quarrel between the local rulers, it was resolved by fixing an ankam, usually a duel. Each ruler would be represented by an ankachekavar. The ruler represented by the winning ankachekavar was considered the winner.
