In ancient times, Assam is known by the name of Pragjyotishpur and Kamarup. In the ancient Sanskrit literature both the names "Prajyotisha" or "Pragjyotishpura" and "Kamrupa" were used as designation for ancient Assam.
The name "Aham" or "Asom" was probably given by the Ahoms who came to Assam in 1228 A.D. Even though the origin is ambiguous but it is believed that the modern name Assam is itself an anglicization.
The Ahom's entered Assam fully assimilated and ruled Assam for nearly six hundred years. The period of Ahom rule is a glorious chapter in the history of Assam. The Ahom dynasty was established by Sukaphaa, a Shan prince of Mong Mao who came to Assam after crossing the Patkai Mountains. It is between 13th and 19th century that several tribal communities also came into the historical forefront of Assam. Kacharis, Chutias and Koch were the prominent tribal groups that were found in the medieval times of Assam. 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 Yandaboo in 1826. The British emperor took charge of the state and thus begun the colonial era of Assam.
