History. The name of the area in Kannada is "Kala-buragi", meaning "stony land." In the 6th century CE, the district was under the control of the Chalukyas. The Rashtrakutas briefly conquered the area, but were driven out by the Chalukyas who ruled the area for the next two centuries. The Kalachuris then conquered the area and ruled it until 12th century, when they were driven out by the Yadavas. Afterwards it was ruled by the Kakatiyas, who ruled until 1324, when their  kingdom fell to the Delhi Sultanate. The ambitions of the local governors led to the formation of the Bahmani sultanate, who made Kalaburagi their capital. The Bahmanis eventually fell and left in their place a patchwork of 5 Deccan Sultanates. Kalaburagi was ruled by the Bidar sultanate until its annexation by Bijapur in 1619. Soon the district would become part of the Mughal Empire, but the Asaf Jahi governors of the Deccan later broke away and formed their own Hyderabad State, and Kalaburagi was ruled by them. This state became a princely state of British India, until its annexation by  India in 1948. Afterwards, Kalaburagi, along with Bidar and Raichur, became part of Karnataka and were known as the Kalyana-Karnataka region. Since this time, this region has continuously been lagging the rest of the state in social indicators and is considered the most backward region of Karnataka. Economy.
