One of the world's oldest mountain ranges, the Aravalli Range, cradles the only hill station of Rajasthan, Mount Abu, and its world-famous Dilwara Temples, a sacred pilgrimage for Jains.

Rajasthan was formed on 30 March 1949, when all erstwhile princely states ruled by Rajputs, known as Rajputana, merged into the Dominion of India. The only difference between erstwhile Rajputana and Rajasthan is that certain portions of what had been British India, in the former province of Ajmer-Merwara, were included. Portions lying geographically outside of Rajputana such as the Sumel-Tappa area were given to Madhya Pradesh.
