Explanation:

The historical account of the state begins in the early part of the 4th century, with the establishment of the Varman Dynasty of Pushya Varman. This dynasty is said to have an aboriginal origin, with links to Narakasura. This was followed by the Mlechchha Dynasty of Salasthamba, which continued till the later part of the 9th century. Following this, a new ruler, Brahmapala was elected, leading to the establishment of a new dynasty called the Pala Dynasty. Due to the fall of subsequent rulers and dynasties, the kingdom of Kamrup finally came to an end in the 12th century A.D.
