The Ahom Kingdom is an Indian state in the Brahmaputra river valley.



The Ahom Kingdom was established by Sukaphaa, a Tai prince in 1228.


Reign of Sudangphaa (1397-1407)

Nothing of note occurred during Sudangphaa's reign except for general improvements and an alliance with Bengal.

Reign of Sujangphaa (1407-1422)

Sujangphaa also improved Assam, and he set out on the first major event in the 1400s for the Ahom Kingdom, the First Ahom-Koch War in 1419. The Ahom asked Bengal for support, but Bengal refused to help. Due to that, the invasion was a terrible failure, and after the defeat, Sujangphaa established an elephant reserve force known as the Ganesha Division and successfully bought war elephants from Bengal to form the unit.

Reign of Suphakphaa (1422-1439)

Suphakphaa did not do anything of note in exception for large military improvements. He  expanded the Ganesha Division to 60, thinking that the elephants would be the most powerful arm of the Ahom Army. Suphakphaa ordered a census in 1427, counting 101,252 people in the kingdom. Also, Suphakphaa introduced a system of coins in 1436.

Reign of Susenphaa the Great (1439-1498)

Title at Death: Susenphaa Mahana, Swargadeo Maharaja of the Ahoms, the Destroyer of the Koch and Chutiya, and the Patel of Koch and Chutiya

Susenphaa improved the Ahom military and mandated that each division have only one cavalry khel and slashed the arquebusier force to 100 men. Susenphaa also led the Ahom army to its first major victory against the Koch at the Second Battle of Bengmara and won the Second Ahom-Koch War. The war led to the annexation of 1/3 of Koch's land by Ahom forces. The victory made Susenphaa a national hero, and the chief advisers agreed to bestow upon him the name "Mahāna", or "the Great". Susenphaa also won the Third Ahom-Koch War in 1451, making his public image become ever more popular, almost to the degree of Sukaphaa. Susenphaa also conquered Koch in a short war in 1452. Susenphaa led the Ahom Kingdom into vassalage under the Sultanate of Bengal. In return, Bengali and Ahom forces crushed Chutiya and annexed it to the Ahom Kingdom.


The Ahom Kingdom is ruled by a monarch known as the Swargadeo Maharaja. The crown is primarily passed through primogeniture, but the monarch's chief advisers, the Great Gohains, could elect a successor. All monarchs had to be descended from the founder of the Ahom Dynasty, Sukaphaa. As of 1460, the Ahom Kingdom became a vassal of the Bengali Sultanate. Bengal will allow the Ahoms to do what they please, in return for the Ahoms providing military support and giving some money to the Bengalis.

The Ahom military is well trained and split into 8 divisions of 6,000 men. Each division is  numbered from 1 to 6 and contains 1,000 men and they are organized into 10 khels of 100 men. Strategically, divisions are able to conduct combat on their own, having infantry, cavalry and archers. Each division has 6 khels of infantry equipped with spears, swords, axes, shields, and traditional hide armor, 1 khel of cavalry equipped with swords, bows, javelins and hide armor, and 3 khels of archers equipped with bows and daggers. 


The Ahom Kingdom uses a type of corvée labor known as the Paik system. The system is neither feudal nor Asiatic and is unique to the Ahom kingdom. Every man between the ages of 15 and 50 who is not a noble, priest, slave, or of a high caste can be used for labor. Also, Suphakphaa introduced a system of coins in 1436. Coins are made of silver and known as raūpa (translation: silver).
