 The "naduvazhi" families each saw themselves as a distinct caste in the same manner as did the rajahs; they did not recognise other "naduvazhi" families as being equal to them.The "naduvazhi" maintained criminal and civil order and could demand military service from all Nairs below him.There was usually a permanent force of between 500 and 1000 men available and these were called upon by the "rajah" when required.
