Durlabh Narayan
Durlabh Narayan was a mid-fourteenth-century king of the Kamata kingdom, ruling from its capital Kamatapur. After his father's cousin Dharma Narayan seized power following the king's death, Durlabh Narayan challenged the usurper and the two partitioned the kingdom, Durlabh Narayan keeping lands including Kamrup, Koch Bihar and Kamatapur.
His court poets Hema Saraswati and Harivara Vipra composed the earliest surviving works of Assamese literature. He was succeeded by his son Indra Narayan, whose reign was shaken by the invasion of Sikandar Shah of Bengal in 1357–1390.
