Karaiyar is a Sri Lankan Tamil caste found mainly on the northern and eastern coastal areas of Sri Lanka, and globally among the Tamil diaspora. They are traditionally a seafaring community that is engaged in fishing, shipment and seaborne trade. They fish customarily in deep seas or on shore, and employ gillnet and seine fishing methods. The Karaiyars were the major maritime traders and boat owners who among other things, traded with pearls, chanks, tobacco, and shipped goods overseas to countries such as India, Myanmar and Indonesia. The community known for their maritime history, are also reputed as a warrior caste who contributed as army and navy soldiers of Tamil kings. They were noted as the army generals and navy captains of the Aryacakravarti dynasty. The Karaiyars emerged in the 1980s as strong representatives of Sri Lankan Tamil nationalism. The nuclear leadership of the Liberation Tigers of Tamil Eelam have background in the wealthier enterprising section of the Karaiyars. Historically, they have also been referred to as Kurukulam, Varunakulam and Karaiyalar. Sharing similar origins and status are the Sinhalese Karava and the Pattanavar of Tamil Nadu. Etymology The word "Karaiyar" is derived from the Tamil language words karai ("coast" or "shore") and yar ("people").

The Portuguese and Dutch sources mentions them under the term Careas, Careaz, or Carias, which are terms denoting "Karaiyar". Kurukulam, Varunakulam and Arasakulam were historically one of the significant clans of the Karaiyars. Kurukulam, meaning "clan of the Kuru", may be a reference to their origin from Kurumandalam (meaning "realm of Kuru's") of Southern India. They attribute their origin myth from the Kuru Kingdom, mentioned in Hindu epic Mahabharata. Some scholars derived Kurukulam from Kuru, the Tamil name for Jupiter. Varunakulam, meaning "clan of Varuna", is a reference to their maritime origin. Varuna is the god of sea and rain, mentioned in Vedic Literature, but also in Sangam literature as the principal deity of the Neithal Sangam landscape (i.e. littoral landscape). Arasakulam means "clan of kings". History Ancient era The Karaiyar, are among the old coastal communities who inhabited the Neithal Sangam landscape.
