The first mention of the name "Rajasthan" appears in the 1829 publication "Annals and Antiquities of Rajasthan" or "The Central and Western Rajpoot States of India", while the earliest known record of "Rajputana" as a name for the region is in George Thomas's 1800 memoir Military Memories. John Keay, in his book India: A History, stated that "Rajputana" was coined by the British in 1829, John Briggs, translating Ferishta's history of early Islamic India, used the phrase "Rajpoot (Rajput) princes" rather than "Indian princes".
