Dera Ghazi Khan: History
=== Foundation ===
Dera Ghazi Khan is named after a Dodai chieftain Ghazi Khan, son of Haji Khan Mirani. It was founded at the end of the 15th century when Baloch tribes were invited to settle the region by Shah Husein, the second Langah Sultan of Multan. Rao Kelana, a powerful Bhati Rajput ruler of Pugal in the 15th century invaded Dera Ghazi Khan and defeated the Balochs. Dera Ghazi Khan was part of Multan province of the Mughal Empire between the 16th and 18th centuries.
Fifteen generations of Miranis ruled the area till the 19th century. In the beginning of the 19th century, Zaman Khan was the ruler of Dera Ghazi Khan under Kabul. ... The area remained under the rule of the Mirani chiefs for several generations.
In the mid-18th century, Mahmud Khan Gujjar (also spelled Muhmud or Mehmood) served as the de facto ruler of Dera Ghazi Khan from around 1738 to 1772. Punjab Government gazetteers credit him with founding the settlement of Mahmud Kot and initiating canal works in the region.
The city was taken by the Sikh army of Ranjit Singh in 1819.The area was invaded by the Sikh Army from Multan under the command of Khushal Singh, general of Ranjit Singh in 1819 and thus Dera Ghazi Khan came under the Sikh rule.
After the success of the Pakistan Movement, which led to the independence of Pakistan in 1947, many Hindus and Sikhs migrated to India while many Muslim refugees from India settled down in the Dera Ghazi Khan District. Many Hindus and Sikhs from Dera Ghazi Khan settled in Delhi and founded Derawal Nagar along with the migrants from Dera Ismail Khan.
