Mainpuri forms part of the ancient legendary region of Lord Krishna's land called Braj.

Mainpuri itself had previously been the seat of Etawah district since 1801, when the British had annexed the territory from the Nawab of Awadh.

[4] Mainpuri formed part of the kingdom of Kanauj, and after its fall it was divided into a number of petty principalities, of which Rapri and Bhongaon were chief.

Mainpuri fell to the Mughal's on Baber’s invasion in 1526, and, although temporarily wrested from them by the short-lived Afghan dynasty of Shere Shah, was again occupied by them on the reinstatement of Humayun after the victory of Panipat.

Like the rest of the lower Doab, towards the end of the 18th century Mainpuri passed into the power of the Maratha Empire and finally became a portion of the province of Oudh.

[6] The six sub-divisions or Tehsils in Mainpuri are as follows: The nine Blocks in Mainpuri are as follows: The district generally gives the appearance of an extensive level plain broken only by the sand ridges on the western border, the rolling sand hills and undulations of the Kali and Isan rivers, and the ravines along the Yamuna to the southwest.

The Kali Nadi forms the boundary of this plain on the north and northeast and the Yamuna encloses it on the southwest.

Generally speaking, the soils of the district are typical of those found elsewhere in the Indo-Gangetic plain, and are classified on two principles according to whether the distinctions recognised are natural or artificial.

The barren soil known as usher is found at the heads and partly down the courses of the smaller rivers such as Ahnaiya and Puraha, the Sengar and Arind and the numerous minor esteems.

A great deal of wasteland is covered with the coarse grass known locally as ganra (gandhar) or sinkh.

Its cultivation has for some time been encouraged by the increase of moisture due to the canals and the great demand for wood both for fuel and carpentry.

Mainpuri abounds in swamps and marshes, particularly in its central portion, but few of them are of sufficient size or permanence to be considered lakes.

There is also a long narrow lake of considerable size to the southwest of Mainpuri city, between it and the Kanpur branch of the Ganges canal, which drains by two cuts towards the Isan.

The general slope of the country, is from northwest to southeast, and this is the direction in which the rivers run and which is therefore followed in the main by the drainage.

According to the 2011 census Mainpuri district has a population of 1,868,529,[1] roughly equal to the nation of Kosovo[9] or the US state of West Virginia.

Its annual Janardhan Swami Temple, and Sivagiri Mutt festivals feature vibrant colors and spiritual expression.

The city fair is held at Sheetla Devi Temple in March or April; the nine days of worshiping the various avatars of the goddess Durga (i.e. Chaitra Navratri) occurs during these months.

[15] The primary exports from Mainpuri district are agricultural products: wheat, pulses, potatoes, oilseeds and oil, rice, and ghee.

The main commercial centres in Mainpuri district are Shikohabad, Bewar, Kusmara, Sirsaganj, and Ghiror.

It is the private property of erstwhile raja of two estates, Mainpuri and Lawan (Dausa, Rajasthan) and repaired, maintained and restored by him.

This bird, called krouncha in India, is revered as a symbol of marital fidelity and is celebrated in myth and legend.
