Bidar is a district of Karnataka state in southern India. The historic city of Bidar is the administrative centre of the district. The district is located in the northeastern corner of the state, near the borders with Andhra Pradesh to the east and Maharashtra to the north and west. Gulbarga district lies to the south.
Kalyani (today called Basavakalyan after Basaveshwara) in Bidar district was the capital of Western Chalukyas, who were also called Kalyani Chalukyas after their capital. The Kalachuris continued with Kalyani as their capital.
The Bahmani capital was shifted from Kalburgi or Kalubaruge(pronounced as Gulbarga and subsequently renamed Ahsanabad by the Muslim newcomers) to Bidar (renamed Muhammadabad by the Bahmanis) in 1425. Bidar remained the capital until the Sultanate's breakup after 1518. It then became the center of the Barid Shahis, one of the five independent sultanates known as the Deccan sultanates. These were the successor states to the Bahmani kingdom.
The Bidar Sultanate was absorbed by the Bijapur Sultanate to the west in 1619, which was in turn included into their Deccan province by the Mughal Emperor Aurangzeb during his viceroyship of Deccan in 1656. After the death of Aurangazeb, Asaf Jah I, the Mughal Subehdar of the Deccan province, became independent and assumed the title Nizam-ul-mulk, with the whole of the province under the Nizam's sovereign control. This status remained unchanged until Operation Polo, when the Nizam's territory was merged to the Republic of India.

The entire district forms a part of the Deccan Plateau and is made up mostly of solidified lava. The northern part of the district is characterized by expanses of level and treeless surface punctuated here and there by flat and undulating hillocks, black soils and basaltic rocks. The southern half of the district is a high plateau about 715 m above mean sea level and are well drained. The average elevation of the district is between 580 to 610 m above mean sea level. Alluvial deposit is normally found along the banks of the Manjra river and its main tributaries.
The district is entirely covered by the Deccan trap flows of the tertiary period. The Deccan trap is composed of horizontal flows of basaltic lava. They generally form flat-topped hillocks and terrace-like features. The physical characteristics of individual flows show considerable variations. Some flows are hard and massive while others are weathered, soft and friable. This character has resulted in terraced landscape, suddenly ending in escarpments. The traps are seen generally 618 m above mean sea level. These are jointed and show the characteristics of spherical weathering leaving massive hard cores. Columnar jointing is predominantly developed in these rocks, besides horizontal joints, which impart to the rocks bedded appearance. The top layers of the Deccan trap in parts of Bidar and Humnabad taluk are altered to reddish vesicular laterite, forming and extensive undulating plateau.
The minerals found in the area are Bauxite, Kaolin and Red ochre. A deposit of highly siliceous bauxite clay has been located about three kilometers south of Basavakalyan. Similar deposits are noticed near Alwal and Kamthana Villages of Bidar taluk. A large deposit of Kaolin is located near Kamthana village. Red ochre deposits are found near Sirsi and Aurad Village.
