Ahom Dynasty - Swargadeo

The Ahom kings (Ahom language: Chao-Pha, Assamese language: Swargadeo), were descendants of the first king Sukaphaa (1228–1268) who came to Assam from Mong Mao in 1228. Succession was by agnatic primogeniture. Nevertheless, following Rudra Singha's deathbed injunction four of his five sons became the king one after the other. The position of Swargadeo was reserved for the descendants of Sukaphaa and they were not eligible for ministerial positions—a division of power that was followed till the end of the dynasty and the kingdom. When the nobles asked Atan Burhagohain to became the king, the Tai priests rejected the idea and he desisted from ascending the throne.

The king could be appointed only with the concurrence of the patra matris (council of ministers—Burhagohain, Borgohain, Borpatrogohain, Borbarua and Borphukan). During three periods in the 14th century, the kingdom had no kings when acceptable candidates were not found. The ministers could remove unacceptable kings, and it used to involve executing the erstwhile king. In the 17th century a power struggle and the increasing number of claimants to the throne resulted in kings being deposed in quick succession, all of whom were executed after the new king was instated. To prevent this bloody end, a new rule was introduced during the reign of Sulikphaa Lora Roja—claimants to the throne had to be physically unblemished—which meant that threats to the throne could be removed by merely slitting the ear of an ambitious prince. Rudra Sinha, suspecting his brother Lechai's intention, mutilated and banished him. The problem of succession remained, and on his deathbed he instructed that all his sons were to become kings. One of his sons, Mohanmala, was superseded, who went on to lead a rebel group during the Moamoria rebellion. The later kings and officers exploited the unblemished rule, leading to weak kings being instated. Kamaleswar Singha (2-year old son of Kadam Dighala) and Purandar Singha (10-year old son of Brajanath and one of the last kings of this dynasty) came into office because their fathers were mutilated.

The Ahom kings were given divine origin. According to Ahom tradition, Sukaphaa was a descendant of Khunlung, who had come down from the heavens and ruled Mong-Ri-Mong-Ram. During the reign of Suhungmung (1497–1539) which saw the composition of the first Assamese Buranji and increased Hindu influence, the Ahom kings were traced to the union of Indra (identified with Lengdon) and Syama (a low-caste woman), and were declared Indravamsa kshatriyas, a lineage created for the Ahoms. Suhungmung adopted the title Swarganarayan, and the later kings were called Swargadeos (Lord of the heavens).
