It is considered that in the 7th century, the kingdom consisted of the modern-day Sunamganj District as well as parts of Habiganj and Mymensingh.

Guhak had a deep interest in Hinduism and migration of Brahmins from the Kamrup region to this area took place.

[4] In 640, the Raja of Tripura Dharma Fa planned a ceremony and invited five Brahmans from Etawah, Mithila and Kannauj.

[5] With the establishment of the East India Company and later the British Raj, Laur continued to exist merely as a pargana or fiscal division, as well as a thana, within greater Sylhet.

[9] In one incident, hill tribes attacked the Laur thana, killing 20 people including the thanadar.

In 1787, the Khasis of Laur also rebelled, plundering many parganas, such as Atgram, Bangsikunda, Ramdiga, Betal and Selharas, and killing up to 800 people.

Before the troops of the Collector of Sylhet, Robert Lindsay, could arrive, the Khasis retreated back to their mountains.
