The "desavazhi" had the right to operate "kalaris", which were military training schools that all young Nair men from the age of 12 were expected to attend. They ceased attending at the age of 18 but were expected to be available for military duty at a day's notice. The function of these schools became less significant practically following the introduction of the Arms Act by the British, which limited the right of Nairs to carry arms; however, they continued to exist and provided some training to those Nair men who did not attend English schools. This training became evident at village festivals, during which a martial review would take place.
