The Pallans are the Jāti Pillais of the Pāndya Kammālans, or Kammālans of the Madura country. The story goes that a long while ago the headman of the Pallans came begging to the Kollan section of the Pāndya Kammālans, which was employed in the manufacture of ploughs and other agricultural implements, and said "Worshipful sirs, we are destitute to the last degree. If you would but take pity on us, we would become your slaves. Give us ploughs and other implements, and we shall ever afterwards obey you." The Kollans, taking pity on them, gave them the implements and they commenced an agricultural life. When the harvest was over, they brought the best portion of the crop, and gave it to the Kollans. From that time, the Pallans became the "sons" of the Pāndya Kammālans, to whom even now they make offerings in gratitude for a bumper crop.
At times of census the Pallans return a number of sub-divisions, and there is a proverb that one can count the number of varieties of rice, but it is impossible to count the divisions of the Pallans. As examples of the sub-divisions, the following may be quoted: —
- Aiya, father.
- Ammā, mother.
- Anja, father.
- Atta, mother.
Dēvendra. — The sweat of Dēvendra, the king of gods, is said to have fallen on a plant growing in water from which arose a child, who is said to have been the original ancestor of the Pallans.
- Kadaiyan, lowest or last.
Konga. — The Kongas of Coimbatore wear a big marriage tāli, said to be the emblem of Sakti, while the other sections wear a small tāli.
