The Tamils (/ˈtæmɪlz, ˈtɑː-/ TAM-ilz, TAHM-), also known as the Tamilar, are a Dravidian ethnolinguistic group who natively speak the Tamil language and trace their ancestry mainly to the southern part of the Indian subcontinent. The Tamil language is one of the longest-surviving classical 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 proportion of the population 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).

The island of Sri Lanka often saw attacks from the Indian mainland with the Cholas establishing their influence across the island and across several areas in Southeast Asia in the 10th century CE. This led to the spread of Tamil influence and contributed to the cultural Indianisation of the region. Scripts brought by Tamil traders like the Grantha and Pallava scripts, induced the development of many Southeast Asian scripts. The Jaffna Kingdom later controlled the Tamil territory in the north of the Sri Lanka from 13th to 17th century CE. European colonization began in the 17th century CE, and continued for two centuries until the middle of the 20th century. (Full article...)
