Ajmer is one of the major and oldest cities in the Indian state of Rajasthan and the centre of the eponymous Ajmer District. It is located at the centre of Rajasthan. It is also known as heart of Rajasthan. The city was established as "Ajayameru" (translated as "Invincible Hills") by a Chahamana ruler, either Ajayaraja I or Ajayaraja II, and served as their capital until the 12th century CE. Ajmer is surrounded by the Aravalli Mountains. Ajmer has been a municipality since 1869. Ajmer has been selected as one of the heritage cities for the HRIDAY and Smart City Mission schemes of the Government of India. History Ajmer was originally known as Ajayameru. The city was founded by an 11th-century 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. This suggests that Ajmer was founded sometime before 1113 CE. 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. A later text Prabandha-Kosha states that it was the 8th-century king Ajayaraja I who commissioned the Ajayameru fort, which later came to be known as the Taragarh fort of Ajmer. 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. Singh theorizes that Ajayaraja II later expanded the town area, constructed palaces, and moved the Chahamana capital from Shakambhari to Ajmer. In 1193, Ajmer was annexed by the Ghurids and later was returned to Rajput rulers under condition of tribute. In 1556, Ajmer came under the Mughal Empire after being conquered by Mughal Emperor Akbar. It was made the capital of the eponymous Ajmer Subah. The city enjoyed special favour under the Mughals, who made frequent pilgrimages to the city to visit the dargah of Moinuddin Chishti. The city was also used as a military base for campaigns against Rajput rulers, and on a number of occasions became the site of celebration when a campaign bore success. 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. Their most prominent building activities were in the dargah and its vicinity. Jahanara Begum and
