After Mauryan empire, the doab came under the control of Shatavahana dynasty which ruled over central and eastern Deccan. Later in the early medieval period, Chalukyas of Badami, Rashtrakutas and Kalyani Chalukyas ruled over the Raichur doab region.In the subsequent centuries, the region was ruled by Kakatiyas of Warangal and Hoysalas before being conquered and annexed by the Delhi Sultanate.

As Bahmani Sultanate was established at Gulbarga in 1347 AD, the region of Raichur doab was fiercely contested and bloody battles were fought over the forts of Mudgal and Raichur between the Bahmanis and Vijayanagar empire. Forces of Vijayanagar empire under Krishnadevaraya won the decisive Battle of Raichur in 1520 CE against Sultanate of Bijapur, and pushed across the Krishna river. But these short-term gains were decisively reversed when a confederate alliance of Deccan Sultanates defeated the Vijayanagar empire at Battle of Talikota in 1565 CE.

During late 17th century, the region came under the Mughal Empire and then passed into the rule of their successors under Nizam of Hyderabad. It remained under the Hyderabad State until 1948 when the princely state was annexed by the Indian Union.
