Kurmi is one of the smallest ethnic groups. They are black and their physical features are very similar to the Dravidian people. British tea growers and traders brought them from Bihar, Purulia and Hajaribagh of India in the late 19th century to engage in tea plantation in Sylhet region of Bangladesh. At present, there are 07 thousand Kurmi who live in Sylhet, Moulavibazar, Habigonj etc.
Kurmis are basically tea garden labourers. However, some of them recently engaged in small trading, low salaried services and tea factory workers. They speak a mixed language comprised of Bangla and Hindi.
Kurmis belong to Hinduism and offer various worships to their gods and goddesses throughout the year. Major worships (puja) performed by them are: Bishohori or Manosha puja in the Bengali month of Bhadra (August-September), Durga puja in Ashwin (September-October), Kali puja in Kartik (October-November), Saraswati puja in Magh (January-February) and Charak puja in the month of Choitra (March-April). Kurmis do not have their own priest. They consider Narayana as the most powerful god. During the Durga puja they organise overnight programmes of traditional drama, jatra and kirton, a session of devotional songs. They play different types of drums called Dhak, Khol and Kartal and instrument like, Flute, Kanshi, Mandira and Kunjari during the musical performance.
