Explanation:

Pratapdhvaj was a minister of Singhadhvaj when he usurped power. At his death, his cousin Dharmanarayan seized power. He was challenged by Pratapdhvaj's son Durlabhnarayan and they decided to settle. Durlabhnarayan assumed power Kamrup, Goalpara, Jalpaiguri, Koch Bihar, along with the capital Kamatapur, while Dharmanarayan retained Rangpur and Mymensingh. As part of the settlement in about 1330, Durlabhnarayan received from Dharmanarayan the custody of fourteen families of Brahmans and Kayasthas, one among whom was Candivara, the great-great-grandfather of Sankardev. The court poets of Durlabhnarayan (Hema Saraswati and Harivara Vipra) and Indranarayan produced literary works that are considered to be the first examples of Early Assamese.
