Greater Tamil Nadu
Greater Tamil Nadu is an irredentist concept of Tamil nationalism that centers on forming a national homeland for the Tamils by merging the Tamil speaking areas of India proper and Sri Lanka. However such areas also include large Kannada and Telugu speaking populations in the northern part, a Malayalam-speaking population in the southwest and Sinhalese people on the islands. Greater Tamil Nadu was proposed by various Tamil groups such as Naam Tamilar led by S. P. Adithanar in 1958 and the Tamil Nadu Liberation Front and the Tamil National Retrieval Troops in the late-1980s.
