Ajmer-Merwara (also known as Ajmir Province, and Ajmer-Merwara-Kekri) was a former province of British India in the historical Ajmer region. The territory was ceded to the British by Daulat Rao Sindhia by a treaty on 25 June 1818. It was under the Bengal Presidency until 1836 when it became part of the North-Western Provinces. Finally on 1 April 1871, it became a separate province as Ajmer-Merwara-Kekri. It became a part of independent India on 15 August 1947 when the British left India. The province consisted of the districts of Ajmer and Merwar, which were physically separated from the rest of British India forming an enclave amidst the many princely states of Rajputana. Unlike these states, which were ruled by local nobles who acknowledged British suzerainty, Ajmer-Merwara was administered directly by the British. In 1842, the two districts were under a single commissioner, then they were separated in 1856 and were administered by the East India Company. Finally, after 1858, by a chief commissioner who was subordinate to the Governor-General of India's agent for the Rajputana Agency. Extent and geography The area of the province was .

The Aravalli Range is the distinguishing feature of the district. The range of hills which runs between Ajmer and Nasirabad marks the watershed of the continent of India. The rain which falls on the southeastern slopes drains into the Chambal, and so into the Bay of Bengal; that which falls on the northwest side into the Luni River, which discharges itself into the Rann of Kutch. The province is on the border of what may be called the arid zone; it is the debatable land between the north-eastern and south-western monsoons, and beyond the influence of either. The south-west monsoon sweeps up the Narmada valley from Bombay and crossing the tableland at Neemuch gives copious supplies to Malwa, Jhalawar and Kota and the countries which lie in the course of the Chambal River. The clouds which strike Kathiawar and Kutch are deprived of a great deal of their moisture by the hills in those countries (now the
