According to a tradition recorded by Joseph Tiefenthaler in the 1700s, Shahabad occupied the site of a former village called Angadpur, after its founder Angad, the nephew of Rama. Modern Shahabad was founded in 1677 by one Nawab Diler Khan, a Pathan officer in the Mughal army, who had been sent to quell an uprising in Shahjahanpur. He overthrew the Pande Parwars of Angni Khera (which, according to H.R. Nevill, is probably the correct form of Tiefenthaler's "Angadpur") and was in turn granted their territory as a jagir, upon which he then founded Shahabad.

Diler Khan populated the new city of Shahabad with fellow Pathan kinsmen and soldiers, and many of the neighbourhoods of the city today bear the names of his followers. He built a brick palace at the centre of town, called the Bari Deorhi, which Tiefenthaler described upon his visit in 1770 as being "strengthened by towers like a fortress, with a vestibule and a covered colonnade." The palace no longer exists, although the two grand gateways are still standing. Diler Khan also built the city's Jama Masjid as well as his own mausoleum. Both of them are built out of dressed kankar blocks. The mausoleum's upper story contains bands of florid decoration in red stone, a style common to architecture of that period which can also be seen in the complex surrounding the Taj Mahal in Agra. He also built a grand pond near the mausoleum, known as Narbada.

Shahabad declined rapidly during the late 1700s, as Mughal power waned and was replaced in this region by the Nawabs of Awadh. Already by 1799, William Tennant described it as being in ruins. In 1824, Reginald Heber, Bishop of Calcutta, traveled to Shahabad and described it as a "considerable town or almost city with the remains of fortifications and many large houses."

The descendants of Nawab Diler Khan Daudzai also moved to a nearby area which under the zamindari and named this place as Wazirabad which is now known as village HARRAI, comes under Tehsil Shahbad, District Hardoi.
