The Tamils (/ˈtæmɪlz, ˈtɑː-/ TAM-ilz, TAHM-), also known by their demonym Tamilar, are a Dravidian ethnic group who natively speak the Tamil language and trace their ancestry mainly to the southern part of the Indian subcontinent. Tamil is one of the longest-surviving languages, with over two thousand years of written history, dating back to the Sangam period (between 300 BCE and 300 CE). Tamils constitute about 5.7% of the Indian population and form the majority in the South Indian state of Tamil Nadu and the union territory of Puducherry. They also form significant proportions of the populations in Sri Lanka (15.3%), Malaysia (7%) and Singapore (5%). Tamils have migrated world-wide since the 19th century CE and a significant population exists in South Africa, Mauritius, Fiji, as well as other regions such as the Southeast Asia, Middle East, Caribbean and parts of the Western World.
Archaeological evidence from Tamil Nadu indicates a continuous history of human occupation for more than 3,800 years. In the Sangam period, Tamilakam was ruled by the Three Crowned Kings of the Cheras, Cholas and Pandyas. Smaller Velir kings and chieftains ruled certain territories and maintained relationship with the larger kingdoms. Urbanisation and mercantile activity developed along the coasts during the later Sangam period with the Tamils influencing the regional trade in the Indian Ocean region. Artifacts obtained from excavations indicate the presence of early trade relations with the Romans. The major kingdoms to rule the region later were the Pallavas (3rd–9th century CE), and the Vijayanagara Empire (14th–17th century CE).
