[2][3] Some historians suggest that this town dates back to the period of Prophet Shees, son of Adam, hence it was named Sheestan, Sewistan and eventually Sehwan.

[4] Syed Muhibullah, the author of "A Brief History of Sind," notes that Sehwan was the name of the great-grandson of Ham (son of Noah).

[6] Notable historian Molai Sheedai writes in his book "Tarikh-e-Tamadan-e-Sind" that Sehwan was built by the Sewi Aryas and was hence called Sewistan.

Sehwan was conquered by Muhammad bin Qasim in 711 from the son of King Dahir, and three centuries later by Mahmud of Ghazni in 1026.

[10] An abortive attempt was made by the Mughal emperor Humayun to capture it on his way to Umarkot in 1542,[11] but it finally fell to his son Akbar in 1590s.

Additionally, the Shrine of Murshid Nadir Ali Shah, a notable spiritual descendant of Lal Shahbaz Qalandar is also located in Sehwan, where a large number of people are served free meals around the clock.

[18] The economy of Sehwan Sharif encompasses a diverse range of sources of income and economic activities that sustain the local populace.

Pilgrimage and Religious Tourism: Sehwan Sharif is renowned for hosting the shrine of Lal Shahbaz Qalandar, a venerated Sufi saint.

The economy of Sehwan Sharif, like that of many regions, is marked by a fusion of traditional and contemporary sectors, evolving to meet the needs of its residents.

On 16 February 2017, a suicide bomber triggered an explosion at the Shrine of Lal Shahbaz Qalandar, killing at least 83 people and injuring almost 250.

[19][20] Later the ISIS claimed responsibility for this terrorist attack stating that their 'martyr' had detonated a vest at the popular Shia gathering at the shrine.
