Tamil literature refers to the literature in the Tamil language. Tamil literature has a rich and long literary 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, Sri Lankan Tamils from Sri Lanka, and from Tamil diaspora. The history of Tamil literature follows the history of Tamil Nadu, closely following the social, political and cultural trends of various periods. The early Sangam literature, starting from the period of 2nd century 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 Hindu, Jain and Buddhist authors, lasting up to the 5th century CE. From the 6th to 12th century CE, the Tamil devotional poems written by Nayanmars (sages of Shaivism) and (Alvars, sages of Vaishnavism) heralded the great Bhakti movement which later engulfed the entire Indian subcontinent. It is during this era that 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. By having the most ancient non-Sanskritized Indian literature, Tamil literature is unique and thus has become the subject of study by scholars who wish to delineate the non-Aryan and pre-Aryan strands in Indian culture. A revival of Tamil literature took place from the late 19th century when works of religious and philosophical nature were written in a style that made it easier for the common people to enjoy. The modern Tamil literary movement started with Subramania Bharathi, the mutlifaceted Indian Nationalist poet and author, and was quickly followed up by many who began to utilize the power of literature in influencing the masses. With growth of literacy, Tamil prose began to blossom and mature. Short stories and novels began to appear. Modern Tamil Literary criticism also evolved. The popularity of Tamil Cinema has also interacted with Tamil literature in some mutually enriching ways.
