[1] Kasganj, which lies in the historical region of Braj, was also known as "Khasganj" during Mughal and British periods.

XV (1908) by William Wilson Hunter,[2] Kasganj came in the hands of James V. Gardner, who was employed by the Marathas and later by the British service.

Famous writer and historian William Dalrymple came to Kasganj in search of Julian Gardner, heir to the English Barony, while researching for his book White Mughals.

[5] The book Wanderings of a Pilgrim in Search of the Picturesque by Fanny Parkes gives details of her visits to Kasganj (then called "Khasgunge") and mentions the town and the Gardner family.

[6] An older description mentioned Kasganj as standing on an elevated site, its drainage flowing towards the Kali Nadi ("black stream"), which runs about a mile southeast of the town.

Kasganj's position in the strategic Indo-Gangetic plain figured in military and political vicissitudes of ancient kingdoms, from the Mahabharata onwards.

It formed part of the grand empire of Harshavardhana, and it finds mention in the accounts of the 7th century Chinese pilgrim Hsien Tsang (Xuanzang), who passed this way in 647 AD.

[9] Research conducted on these artifacts suggests that Kasganj has had a rich history since ancient and medieval times.

[citation needed] The inscription regarding its establishment is still visible in the city's Jama Masjid ("big mosque").

The frequency of road and rail transport to and from Kasganj makes it easily accessible throughout the year.

Since the construction of the road bridge on the "Gangaji," it is very convenient to travel toward the Budaun and Bareilly side.

It lies on a trijunction and it is connected to Mathura, Kanpur and Bareilly through rail network in three different directions.
