Tamil Nationalism is a political and cultural movement that seeks to promote the rights and identity of the Tamil people, primarily in Sri Lanka and India. It emphasizes the preservation of the Tamil language, culture, and heritage, advocating for self-determination and autonomy for Tamil regions. The movement gained prominence during the 20th century, particularly in response to perceived discrimination against Tamils. Key events include the rise of political parties like the Dravida Munnetra Kazhagam (DMK) and the Liberation Tigers of Tamil Eelam (LTTE), which fought for an independent Tamil state in Sri Lanka.
