Keerandhaiyar is believed to have belonged to the
Brahmin caste of the Keerar tribe, who changed their occupation from yagna to
performing arts. These people primarily spoke
Sanskrit but have adapted themselves to the
Tamil culture and language. He belonged to the
Aryan race who had come down south and settled down in the
Tamil land since
antiquity. There were about 24 poets of the Sangam era who belonged to this tribe, including
Nakkirar I and
Kanakkaayanar. ==Contribution to the Sangam literature==
