According to a tradition, Dinajpur derived its name from Raja Dinaj or Dinaraj who founded the Dinajpur Raj (the estate of Dinajpur). But according to another tradition, Raja Ganesha was the real founder of this estate. In the late 17th century Srimanta Dutta Chaudhury (s/o Harish Chandra) from Andul Dutta Chaudhury Family became the zamindar of Dinajpur.
