The Kalachuris (IAST: Kalacuri), also known as Kalachuris of Mahishmati, were an Indian dynasty that ruled in west-central India between 6th and 7th centuries. They are also known as the Haihayas or as the Early Kalachuris to distinguish them from their later namesakes, especially the Kalachuris of Tripuri. The Kalachuri territory included parts of present-day Gujarat, Madhya Pradesh, and Maharashtra. Their capital was probably located at Mahishmati. Epigraphic and numismatic evidence suggests that the earliest of the Ellora and Elephanta cave monuments were built during the Kalachuri rule. The origin of the dynasty is uncertain. In the 6th century, the Kalachuris gained control of the territories formerly ruled by the Guptas, the Vakatakas and the Vishnukundinas. Only three Kalachuri kings are known from inscriptional evidence: Shankaragana, Krishnaraja, and Buddharaja. The Kalachuris lost their power to the Chalukyas of Vatapi in the 7th century. One theory connects the later Kalachuri dynasties of Tripuri and Kalyani to the Kalachuris of Mahishmati. According to the Kalachuri inscriptions, the dynasty controlled Ujjayini, Vidisha and Anandapura. Literary references suggest that their capital was located at Mahishmati in the Malwa region. The dynasty also controlled Vidarbha, where they succeeded the Vakataka and the Vishnukundina dynasties. In addition, the Kalachuris conquered northern Konkan (around Elephanta) by the mid-6th century. Here, they succeeded the Traikutaka dynasty. The origin of the Kalachuris is uncertain. The city of Kalanjara-pura was culturally important to them as it was their gotra's origin-place. On inscriptions, Kalachuris are variously known as Kalachuri, Kalatsuri, and Katatchuri. Katachchuri was another causing. These inscriptions were epigraphs. Krishnaraja (r. c. 550-575) is the earliest known ruler of the dynasty. He issued coins featuring Brahmi script legends, imitating the design of earlier coins issued by the Traikutaka and the Gupta kings. His coins featuring a bull are based on the coins issued by Skandagupta.
