The name asama (as well as acam, asam, asam, asam) was used in the form asamakshara to denote the Ahom script in Sanskrit-Ahom bilingual copper plate grants of the Ahom kings. Mughal forms As opposed to the local uses, where Asam and similar formations were used to denote the Ahom community, external sources used variations of Asam to denote the kingdom ruled by the Ahoms. The Ain-I-Akbari of the sixteenth century uses the form Asham (آشام) to denote the Ahom kingdom. The official chronicler of Mir Jumla also calls the place "Asam". European forms The earliest Europeans who came in contact with Assam (and who had the opportunity to write the name in the Latin script), were travelers who went to Bengal and adventurers who accompanied military expeditions against the Ahom kingdom; these groups used variations of the name Asam to denote the kingdom. In a map of "Kingdom of Bengale", drawn by Joh. van Leenen around 1661 and published around 1662, Assam was clearly named and correctly identified. One of the first unambiguous references comes from Thomas Bowrey in 1663 about Mir Jumla's death: "They lost the best of Nabobs, the Kingdome of Acham, and, by consequence, many large privileges". Though Bowrey wrote his manuscript in the 17th century, the manuscript itself was published for the first time in the 20th century. On the other hand, Jean-Baptiste Tavernier's Travels in India, published in 1676 uses the spelling "Assem" for Assam in the French original (Aſem in the English translation, published in 1678). Thus the earliest English use of the name was "Aſem", with a Long s. Colonialists then followed these travelers and adventurers. Both Grierson and Gait agree that the British used Asam before finally settling on Assam. In various documents of the British East India Company relating to the last few Ahom kings, the name of country was mentioned as Assam. The 1826 Treaty of Yandabo, marking the conquest of the Ahom kingdom at the hands of the British, uses Assam to denote the area under the erstwhile Ahoms and its protectorates (Darrang Koch, Jaintias, Kacharis and some hill areas in the present Arunachal Pradesh and Nagaland). After the British took control of the region, the name Assam was extended to the province that was then much larger than the Ahom kingdom. It then included, Garo Hills and Lushai Hills (Mizoram). Since that time, the boundaries of Assam
