The dynasty was established by Sukaphaa, a Shan prince of Mong Mao (present-day Yunnan, China) who came to Assam after crossing the Patkai mountains.
The rule of this dynasty ended with the Burmese invasion of Assam and the subsequent annexation by the British East India Company following the Treaty of Yandabo in 1826.
When the nobles asked Atan Burhagohain to become the king, the Tai priests rejected the idea and he desisted from ascending the throne.
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 exclusively for the Ahoms.
[3] Suhungmung adopted the title Swarganarayan, and the later kings were called Swargadeo's (literal meaning: Lord of the Heavens).
The first Charing Raja was Sukhramphaa's half-brother, Chao Pulai, the son of the Kamata princess Rajani, but who did not ultimately become the Swargadeo.
Suhungmung Dihingia Raja (1497–1539) settled the descendants of past kings in different regions that gave rise to seven royal houses—Saringiya, Tipamiya, Dihingiya, Samuguriya, Tungkhungiya, Parvatiya and Namrupiya—and periods of Ahom rule came to be known after these families.
Sukaphaa's ruling deity was Chum-Pha and Sheng-mung a pair of non-Hindu, non-Buddhist gods, and he was accompanied by classes of priests called Deodhai, Bailung etc.
Sudangphaa Bamuni Konwar (1397–1407) installed a Brahmin of Habung, in whose household he was born and raised, as his adviser, but he himself did not convert to Hinduism.
[7] Suhungmung Dihingia Rojaa (1497–1539) was the first Ahom king to expand the kingdom and the polity, allow Assamese influence in his court and accept a non-Ahom title—Swarganarayan.
[8] Sukhaamphaa Khora Rojaa (1552–1603) began consulting Hindu astrologers alongside the traditional Deodhai-Bailung priests, and Pratap Singha (1603–1641) installed 13 Brahmin families as diplomats.
After the chaos of the late 17th century, Gadadhar Sinha (1681–1696), the first Tungkhungiya king began his rule with a deep distrust of these religious groups.
The persecution of the Mahapuruxiya Sattras under the Tunkhungiya rulers following Siba Singha was a crucial factor leading to the Moamoria rebellion that greatly depleted the Ahom kingdom.
Several classes of highly trusted guards were entrusted with the duty of protecting the king, which were duly supervised by the superior officers.
[citation needed] The dynastic history and dates that are accepted today are the result of a re-examination of Ahom and other documents by a team of Nora astronomers and experts who were commissioned to do so by Gaurinath Singha (1780–1795).
