Angampora is the traditional martial art of Sinhalese. It combines combat techniques, self-defense, sport, exercise and meditation. Key techniques observed in Angampora are: Angam,
which incorporates hand-to-hand fighting, and Illangam, which uses indigenous weapons such as Velayudaya, staves, knives and swords. Its most distinct feature is the use of pressure
point attacks to inflict pain or permanently paralyse the opponent. Fighters usually make use of both striking and grappling techniques, and fight until the opponent is caught in a
submission lock that they cannot escape. Usage of weapons is discretionary. Perimeters of fighting are defined in advance, and in some of the cases is a pit. Angampora became nearly
extinct after the country came under British rule in 1815, but survived in a few families until the country regained the independence.
