[2] According to the 16th-century writer and author of the Tārīkh-i ḥaqqī, Abd al-Haqq, the founder of the dynasty was one "Buddhan Khan Sindhi", chief of the Langah tribe of the Baloch.

[2] The place of origins for Langah sultans is similarly disputed, with Siwi (modern Sibi) and Rapar in Mailsi near Multan being usually suggested.

In 1445, Rai Sahra, chief of the Langah, attacked the city at night with the help of his tribesmen, arrested Sheikh Yousaf and proclaimed himself sultan.

[1] Multan experienced prosperity during this time, and a large number of Baloch settlers arrived in the city at the invitation of Shah Husayn.

[1] During the rule of the Langah, a large number of Baloch tribes were allowed to settle in the Derajaat Border in turn for military service.

[8][1] Sultan Husayn I being unable to hold his trans-Indus possessions, assigned the region around Dera Ismail Khan to Sardar Malik Sohrab Dodai in 1469 or 1471 and appointed him as "Jagirdar".

The city was invaded during the reign of Sultan Husseyn II by ruler Shah Husayn of the Arghun dynasty, probably at Babur's insistence.

[1] Multan fell in 1528 after an extended siege and Shah Husayn appointed his son Mirza Askari as governor of the city, assisted by Langar Khan, one of the powerful Amirs of Sultan Mahmud Langah I.
