Tamil communities are groups of people who share a common language, culture, and heritage rooted in the Tamil language, which is one of the oldest living languages in the world. They primarily inhabit the Indian state of Tamil Nadu and the northern and eastern regions of Sri Lanka. Beyond these regions, Tamil communities can be found globally, particularly in countries like Malaysia, Singapore, and Canada, where they have established vibrant diasporas. These communities maintain their cultural practices, including traditional festivals like Pongal and Thaipusam, while also contributing to the multicultural fabric of their host countries.
