Kishorganj consists of eight municipalities, 13 upazilas, 105 union parishads, 39 wards, 145 mahallas, 946 mouzas and 1775 villages.

The village of Egarosindur in Pakundia Upazila has evidence of trade with distant foreign countries dating back at least 2500 years.

It was part of the Pala and Sena empires, and after their fall it was mainly administered by a large number of petty Koch and Barman chieftains.

In 1580, Isa Khan defeated the Koch chieftain of Jangalbari and took over the entirety of Kishoreganj in his domain.

[5] After his death and his son's surrender, most of present day Kishoreganj district formed part of Musa Khan's domain.

The western part of the district is composed primarily of alluvial silt and clay deposits with a few beels.

The eastern part of the district lies in a shallow basin composed of marshy clay and peat.

The Ghorautra then meanders southwest, before turning slightly to flow south and joins the Kalni, near the village of Dilalpur to form the Meghna.

It flows south through Mithamain and Ashtagram upazilas before forming the border with Brahmanbaria district.

Kishoreganj District had a literacy rate (age 7 and over) of 67.60%, compared to the national average of 74.80%, and a sex ratio of 1077 females per 1000 males.

The overwhelming majority of its residents are Muslim, while the Hindu population has remained constant over time.

[5] It was once a strong outpost of the Bengal Ruler Isa Khan, who erected several structures inside the fort area.

Some engraved silver coins, iron-axes, lances and bows and arrows were discovered there presumed to be from the 10th century BC.

In the beginning of 14th century the king of Gaur, Firoz Shah succeed to win Egarosindur.

In the fort of Egarosindur there held a massive battle between Isa Khan and Mansingh, the general of Akbar.

Though he was not competent to defeat the warrior of Shahjahan, he destroyed this land ruthlessly when he fled from the battlefield.

The mosque stands at the back of a slightly raised platform, which is enclosed by a low wall with a gateway consists of an oblong structure with do-chala roof.

The mosque proper is a square structure, 5.79m a side in the inside, and is emphasized with octagonal towers on the four exteriors angles.

All these towers shooting high above the roof and terminating in solid kiosks with cupolas, were originally crowned with kalasa finials, still intact in the southern one.

The pilasters, supporting the mihrab arches, show a series of decorated bands topped by a frieze of petals.

Above the rectangular frame of the central mihrab there is a row of arched-niches filled with varieties of small trees containing flowers.

The mosque should specially be noted for its four axially projected frontons with bordering ornamental turrets, a device which must have been borrowed from the four axial iwan-type gateways of the Persian influenced north Indian Mughal standard mosques of Fathpur, Agra and Delhi.

A pertain inscription tablet, fixed over the central mihrab, record that the mosque was built in 1062 AH (1652 AD) by one Sadi, son of Shaikh Shiroo, during the reign of Shahjahan.

Measuring 25 ft a side, the single-domed square mosque was built on a raised piece of land.

The mosque represents a happy blending of Mughal elements with the Sultanate architectural traits characteristic of Bengal.

Poet Chandravati Shiv Mandir The Chandravati Shiv Mondir (Temple) built at Katcharipara about 8 kilometres off Kishoreganj town by Deeja Bongshi Das during the later part of 16th century is still adorned with its artistic structural workmanship which attracts the tourists of different areas.
