Explanation:

 Ajmer was originally known as Ajayameru. The 12th century text Prithviraja Vijaya states that the Shakambhari Chahamana (Chauhan) king Ajayaraja II (ruled c. 1110 – 1135 CE) established the city of Ajayameru.[4] 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.
