Karaikudi in the context of "Government of Tamil Nadu"

The Tamil Sangams (Tamil: சங்கம் caṅkam, Old Tamil 𑀘𑀗𑁆𑀓𑀫𑁆, from Sanskrit saṅgha) were three legendary gatherings of Tamil scholars and poets that, according to traditional Tamil accounts, occurred in the remote past. Scholars believe that these assemblies were originally known as kooṭam or "gathering," which was also a name for Madurai. Three assemblies are described. The legend has it that the first two were held in cities since "taken by the sea", the first being called Kapatapuram, and the third was held in the present-day city of Madurai.

Tamil literature includes a collection of literary works that have come from a tradition spanning more than two thousand years. The oldest extant works show signs of maturity indicating an even longer period of evolution. Contributors to the Tamil literature are mainly from Tamil people from south India, including the land now comprising Tamil Nadu, Kerala, Eelam Tamils from Sri Lanka, as well as the Tamil diaspora.

The history of Tamil literature follows the history of Tamil Nadu, closely following the social, economical, political and cultural trends of various periods. The early Sangam literature, dated before 300 BCE, contain anthologies of various poets dealing with many aspects of life, including love, war, social values and religion. This was followed by the early epics and moral literature, authored by Vaishnavite, Shaivite, Ājīvika, Jain and Buddhist authors and poets lasting up to the 5th century CE. From the 6th to 12th century CE, the Tamil devotional poems written by Alvars (sages of Vaishnavism) and Nayanmars (sages of Shaivism) and, heralded the great Bhakti movement which later engulfed the entire Indian subcontinent. During the medieval era some of the grandest of Tamil literary classics like Kambaramayanam and Periya Puranam were authored and many poets were patronized by the imperial Chola and Pandya empires. The later medieval period saw many assorted minor literary works and also contributions by a few Muslim and European authors.

Tamil Thai (alternatively spelled Tamil Tai or Thamizh Thai), known in English as Mother Tamil, refers to the allegorical and sometimes anthropomorphic personification of the Tamil language as a mother. There is a temple located in Karaikudi. This allegory of the Tamil language in the persona of a mother was established during the Tamil renaissance movement of the latter half of the nineteenth century. The concept became popular in the Tamil-speaking world after the publication of a song invoking and praising Tamil mother in a play titled, "Manonmaniyam", written by Manonmaniam Sundaram Pillai (1855 – 1897) and published in 1891. Under the auspices of the DMK, the Tamil Thai Valthu, with music composed by M.S. Viswanathan, has since been adopted as the state song of the Government of Tamil Nadu.
