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. Pratapdhvaj (1305–1325) Dharma Narayan (1325–1330) Durlabh Narayan (1330–1350) Indra Narayan (1350–1365) Baro-Bhuyan rule The invasion of Assam by Sikandar Shah (1357–1390) weakened Indranarayan. Though Shah had to retreat from central Assam because of an attack on Bengal by Firuz Shah Tughlaq, Indranarayana was sufficiently damaged that a Bhuyan from Darrang, Arimatta, was able to usurp power. Sasanka (Arimatta) (1365–1385) Gajanka (1385–1400) Sukranka (1400–1415) Mriganka Jungal Balahu (1415–1440) Khen dynasty The Khen dynasty, of Kheng-Bhutanese affiliation, replaced the weak rulers of Kamata kingdom following Arimatta in the middle of the 15th century. Niladhvaj Khen, the first king, united several Baro-Bhuyan chieftains of the area and removed the last of Arimatta's successors—Mriganka. There were only three Khen rulers. Niladhwaj (1440–1460) Chakradhwaj (1460–1480) Nilambar (1480–1498) The last king, Nilambar expanded the kingdom to include the present Koch Bihar districts of West Bengal and the undivided Kamrup and Darrang districts of Assam and northern Mymensingh in Bangladesh as well as eastern parts of Dinajpur district, though he was removed by Alauddin Husain Shah in 1498. Bengal Sultanate rule Alauddin Hussain Shah, a Sultan of Bengal, removed the last Khen ruler in 1498. This followed a long siege that likely started in 1493 soon after Alauddin's ascension and ended in a treacherous win with 24,000 infantry, cavalry and a war flotilla. Alauddin destroyed the city and eventually annexed the region up to Hajo by 1502, removed the local chieftains, and established military control over the region. He established his son Shahzada Danyal as an administrator and issued coins in his own name as the "conqueror of Kamru and Kamata ...". This rule was short since the Baro-Bhuyans rose up in revolt soon after and exterminated Sultanate rule. Shahzada Danyal (c1498-c1509) Nevertheless, the Muslim rule had lasting effects. Hussein Shah's coins continued to be used till 1518, when the Koch dynasty began consolidating their rule. Ghiasuddin Aulia, a Muslim divine figure from Mecca, established a colony at Hajo. His tomb, which is said to contain a little soil from Mecca, now called "Poa Mecca" ("a quarter Mecca"), is frequented by Hindus
