The Kamata kingdom (pron: ˈkʌmətɑ:, Assamese: কমতা ৰাজ্য) appeared in the western part of the older Kamarupa kingdom in the 13th century, after the fall of the Pala dynasty. The rise of the Kamata kingdom marked the end of the ancient period in the History of Assam and the beginning of the medieval period. The last rulers were the Khens, who were later displaced by Alauddin Hussain Shah, the Turko-Afghan ruler of Gauda. Though Hussain Shah developed extensive administrative structures, he could not maintain political control and the control went to the Koch dynasty.
