A Gujarati historic novel named Gujaratno Jay written by Zaverchand Meghani, based on various Jain Prabandhas, describes the city as sapādalakṣaṇa (સપાદલક્ષણ).

Maharaja of Parmar Rajputs founded the Ajmer city in the 11th-century, which was admired from Chahamana king Ajaydeva.

Historian Dasharatha Sharma notes that the earliest mention of the city's name occurs in Palha's Pattavali, which was copied in 1113 CE (1170 VS) at Dhara.

[12] A prashasti (eulogistic inscription), issued by Vigraharaja IV and found at Adhai Din Ka Jhonpra (Sanskrit college), states Ajayadeva (that is Ajayaraja II) moved his residence to Ajmer.

[14] According to historian R. B. Singh, this claim appears to be true, as inscriptions dated to the 8th century CE have been found at Ajmer.

[15] Singh theorises that Ajayaraja II later expanded the town area, constructed palaces, and moved the Chahamana capital from Shakambhari to Ajmer.

Mughal Emperors and their nobles made generous donations to the city, and endowed it with constructions such as Akbar's palace and pavilions along the Ana Sagar.

[29] At the time of India's independence in 1947, Ajmer continued as a separate state with its own legislature until its merger with erstwhile Rajputana province, then called Rajasthan.

It had 30 MLAs, and Haribhau Upadhyay was the first chief minister of the erstwhile state, with Bhagirath Chaudhary as the first Vidhan Sabha speaker.

The winter months of November to February are mild and temperate with average temperatures ranging from 15–18 °C (59–64 °F) with little or no humidity.

[38] Divisional commissner of Ajmer is Bhanwar Lal Mehra and district collector is Ansh Deep.

The Ajmer Airport ground breaking ceremony was done by then Prime Minister of India Manmohan Singh in 2012.

[53] The airport is operational since then and regular flights to/from Delhi, Mumbai, Hyderabad, Ahmedabad, Indore and Surat are currently available.
