Explanation:

The Ahom dynasty (1228–1826) ruled the Ahom kingdom in present-day Assam, India for nearly 598 years. The dynasty was established by Sukaphaa, a Shan prince of Mong Mao 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. In external medieval chronicles the kings of this dynasty were called Asam Raja, whereas the subjects of the kingdom called them Chaopha (Chao-ruler, Pha-heaven), or Swargadeo (the equivalent in Assamese).
