AnkaKalari (Malayalam അങ്ഗകളരി) - is the arena where an Ankam (duel) is fought. The Ankathattu (a platform constructed temporarily for the purpose of fighting duels) is built in the center of the area from which all spectators can watch the fight. This area, including the platform and observation area, is called an AnkaKalari.

Centuries ago, in Kerala, South India, if there was a quarrel between the local rulers, instead of engaging in an Ankam (war), usually a duel would be arranged. Each ruler would be represented by an Ankachekavar. The ruler of the kingdom that the Ankachekavar who wins the fight was fighting for is considered the winner of the conflict, and is treated as though they have won a pitched war.
