The Kanakkans belong to the slave castes, and are even now attached to some landlords. In the taluks of Trichur, Mukandapuram, and Cranganur, where I obtained all my information about them, I learnt that they are the Atiyars (slaves) of Chittur Manakkal Nambudiripad at Perumanom near Trichur, and they owe him a kind of allegiance. The Nambudiri landlord told me that the members of the caste, not only from almost all parts of the State, but also from the British taluks of Ponnani, Chowghat, and even from Calicut, come to him with a Thirumulkazhcha, i.e., a few annas in token of their allegiance. This fact was also confirmed by a Kanakkanar (headman) at Cranganur, who told me that he and his castemen were the slaves of the same landlord, though, in disputes connected with the caste, they abide by the decision of the local Raja. In the event of illness or calamity in the family of a Kanakkan, an astrologer (Kaniyan), who is consulted as to the cause and remedy, sometimes reminds the members thereof of the negligence in their allegiance to the landlord, and suggests the advisability of paying respects to him (Nambikuru) with a few annas. On the Puyam day in Makaram (January-February), these people from various parts of the State present themselves in a body with a few annas each, to own their allegiance to him. The following story is mentioned by him. One of his ancestors chanced to pay his respects to one of the rulers of the State, when the residence of the Royal Family was in Cochin. On arriving near the town, the boat capsised in a storm, but was luckily saved by the bravery of a few rowers of this caste. The Raja, who witnessed the incident from a window of his palace, admired their valour, and desired to enlist some Kanakkans into his service. There are four endogamous sub-divisions among the Kanakkans, viz., Patunna, the members of which formerly worked in salt-pans, Vettuva, Chavala, and Parattu. Each of these is further sub-divided into clans (kiriyam), which are exogamous. A young man may marry the daughter of his maternal uncle, but this is not permissible in some places. Marriage is both infant and adult, and may be celebrated by Patunna Kanakkans at any time between the tenth and thirteenth years of a girl, while the Vettuva Kanakkans may celebrate it only after girls attain puberty. They often choose the bridegroom beforehand, with the intention of performing the ceremony after puberty.
