Dewan Hason Raja Chowdhury, or simply known as Hason Raja (; 21 December 1854 – 6 December 1922), was a Bengali mystic poet and songwriter from Sylhet, Bengal Presidency (now Bangladesh). His unique style of music made him one of the most prominent figures in Bengali folk culture. Biography Early life Raja was born on December 1854 in Lakshmansree, now Sunamganj to a Bengali Muslim zamindar family. His father was Dewan Ali Raja, the grandson of Birendraram Singhdev. His great-grandfather later converted from Hinduism to Islam and changed his name to Dewan Raja Babu Khan. Hason Raja's mother was Hurmat Jahan Bibi, the last and fifth wife of Dewan Ali Raja Chowdhury of Kauriya.
