South Asia's regional kingdoms, 1000–1550

Between the Ghaznavid raids and the Mughal conquest, South Asia was shared by dozens of regional states: the Madurai Sultanate in the Tamil country, the sultanates of Gujarat, Malwa and Khandesh, the Reddi and Velama kingdoms of Andhra, the Gajapatis of Odisha, the Rajput kingdoms of Mewar and Marwar, the Ahom, Chutia, Kamata and Tripura kingdoms of the north-east, the successors of the Chera Perumals on the Malabar coast, and the Sinhala kingdoms of Gampola, Kotte and Kandy. Few medieval sources describe frontiers.
