Ajmer District has an area of 8,481 km2, and a population of 2,583,052 (2011 census). There are 1,869,044 Hindus, 244,341 Muslims and 47,812 Jains. The district is situated in the center of Rajasthan, and is bounded by Nagaur district to the north, Jaipur and Tonk districts to the east, Bhilwara district to the south, and Pali district to the west.
The hills are some of the oldest in India, geologically. Microliths from early hominids have been found in the district. It is believed that cultures in this region had contact with the Indus Valley civilization. Pottery shards from Painted Gray Ware culture, Black and Red Ware and Northern Black Polished Ware cultures have been found with Chosla and Sameliya. Some pre-Ashokan Brahmi inscriptions have been found in Bhilot Mata Temple in Badli.
Pushkar was ruled for many years by the Kushans, Sakas etc until the rise of the Chauhans. In 1192 the last independent Chauhan ruler Prithviraj Chauhan was defeated by Mohammad Ghori, and the district became part of the Delhi Sultanate. In 1287, Hammir Dev Chauhan regained Ajmer, before it was reconquered by Delhi in 1301. In the last period of the Delhi Sultanate, Ajmer was ruled by Mallu Khan. During Mughal rule the district was part of Ajmer Subah. After 1712, the district returned to Rathore hands under the suzereinty of the Marathas. In 1801, the British took over Ajmer and converted it to a district. It became part of Rajasthan after 1950.
The eastern portion of the district is generally flat, broken only by gentle undulations. The western parts, from north-west to south-west, are intersected by the Aravalli Range. Many of the valleys in this region are sandy deserts, part of India's Thar Desert, with an occasional oasis of cultivation. Some fertile tracts are also present; among these is the plain on which lies the town of Ajmer. This valley has an artificial lake, and is protected by the massive walls of the Nagpathar range or Serpent rock, which forms a barrier against the sand. The only hills in the district are the Aravalli Range and its offshoots. Ajmer is almost totally devoid of rivers. The Banas River touches the south-eastern boundary of the district so as to irrigate the pargana of Samur. Four small streams—the Sagarmati, Saraswati, Khari and Dai—also intersect the district.
The district is divided into four subdivisions, Ajmer, Beawar, Kekri and Kishangarh, and further subdivided into sixteen tehsils, Ajmer, Arai, Beawar, Bhinai, Pushkar, Sarwar, Pisangan, Tantoti, Nasirabad, Masuda, Kekri, Kishangarh, Roopangarh, Bijay Nagar, Tatgarh, Sanver
