R?jput?na, meaning "Land of the Rajputs", was a region in India that included mainly the present-day Indian state of Rajasthan, as well as parts of Madhya Pradesh and Gujarat, and some adjoining areas of Sindh in modern-day southern Pakistan. The main settlements were to the west of the Aravalli Hills, and was known as Samarkand, the earlier form of Registan, before it came to be known as Rajputana, early in the Medieval Period. The name was later adopted by British government as the Rajputana Agency for its dependencies in the region of the present-day Indian state of R?jasth?n. The Rajputana Agency included 18 princely states, two chiefships and the British district of Ajmer-Merwara. This British official term remained until its replacement by "Rajasthan" in the constitution of 1949.
George Thomas (Military Memories) was the first in 1800, to term this region the Rajputana Agency. The historian John Keay in his book, India: A History, stated that the Rajputana name was coined by the British, but that the word achieved a retrospective authenticity: in an 1829 translation of Ferishta's history of early Islamic India, John Briggs discarded the phrase "Indian princes", as rendered in Dow's earlier version, and substituted "Rajpoot princes".
The area of Rajputana is estimated to be 343,328 square km (132,559 square miles) and breaks down into two geographic divisions:
Colonel James Tod, who as the first British official to visit Rajasthan spent most of the 1820s exploring its political potential, formed a very different idea of "Rashboots".....and the whole region thenceforth became, for the British, 'Rajputana'. Historian R. C. Majumdar explained that the region was long known as Gurjaratra early form of Gujarat, before it came to be called Rajputana, early in the Muslim period.
