The founder of the Mughal empire, Babur, described his favourite type of garden as a charbagh. They use the term bāgh, baug, bageecha or bagicha for garden. This word developed a new meaning in India, as Babur explains; India lacked the fast-flowing streams required for the Central Asian charbagh. The Agra garden, now known as the Ram Bagh, is thought to have been the first charbagh. India, Bangladesh and Pakistan have a number of Mughal gardens which differ from their Central Asian predecessors with respect to "the highly disciplined geometry". An early textual references about Mughal gardens are found in the memoirs and biographies of the Mughal emperors, including those of Babur, Humayun and Akbar. Later references are found from "the accounts of India" written by various European travellers (Bernier for example). The first serious historical study of Mughal gardens was written by Constance Villiers-Stuart, with the title Gardens of the Great Mughals (1913). Her husband was a Colonel in Britain s Indian army. This gave her a good network of contacts and an opportunity to travel. During their residence at Pinjore Gardens, Mrs. Villiers-Stuart also had an opportunity to direct the maintenance of an important Mughal garden. Her book makes reference to the forthcoming design of a garden in the Government House at New Delhi (now known as Rashtrapati Bhavan). She was consulted by Edwin Lutyens, and this may have influenced his choice of Mughal style for this project. Recent scholarly work on the history of Mughal gardens has been carried out under the auspicious guidance of Dumbarton Oaks (including Mughal Gardens: Sources, Places, Representations, and Prospects edited by James L. Wescoat, Jr. and Joachim Wolschke-Bulmahn) and the Smithsonian Institution. Some examples of Mughal gardens are Shalimar Gardens (Lahore), Lalbagh Fort at Dhaka, and Shalimar Bagh (Srinagar).
