Dera Ghazi Khan was founded by Haji Khan which was
called after the name of his son Ghazi Khan who died in 1494 A.D.
Before the first Muslim invasion in the area now comprising the
district there was only one town i.e. Mari, the rest of the country
was un-inhabited. It was remarkably connected by tradition with
Rasalu, the legendary hero and his opponent Raja Sirkap. Towards the
mid of the 19th century (or in 1849) on conclusion of the second
Sikh War, the district was annexed by the British. Adjustment in
boundaries between D.G. Khan & Dera Ismail Khan districts took place
between 1866-97 A.D.
