Chakmas, as per their oral history, are believed to have migrated to Arakan from the ancient kingdom of Magadha which is part of the present Bihar state of India. They believe they are also part of Buddha's Sakya clan from Himalayan tribes. After many struggles to survive, they gradually migrated to Arakan, and spread their territory to the nearby hills of Chittagong Hill Tracts. They signed a treaty with Mughal Bengal in 1717. The government of British India provided tribal autonomy to the area which continued after the partition of India. During the construction of the Kaptai Dam in the 1960s, many Chakma settlements were submerged due to the creation of the artificial Kaptai Lake. In the mid-1970s, the eruption of the Chittagong Hill Tracts conflict caused some Chakma people to permanently settled in NEFA [[North-East Frontier Agency [(present [[Arunachal Pradesh]]) by the Central Government of India as the erstwhile NEFA was scanty populated and mostly a dense forest. They also have close religious identifications with that of the local tribes like Singphos and Kamtis of NEFA. The authorities then thought that this will help themselve establish peaceful and harmonious living. The conflict ended in 1997 with the [[Chittagong Hill Tracts Peace Accord]]. Today, Chakma communities are found in Bangladesh, India and Myanmar. In Myanmar Chakma people are known as [[Daingnet people]]. Notable Chakma people include [[Bhuvan Mohan Roy]], [[Nalinaksha Roy]], [[Benita Roy]], [[Tridev Roy]], [[Debashish Roy]], [[Chandra Kalindi Roy Henriksen]], [[Manabendra Narayan Larma]], [[Jyotirindra Bodhipriya Larma]], [[Kalpana Chakma]], [[Kanak Chanpa Chakma]] and [[Amit Chakma]]. Chakma people also serve as officers and ambassadors in Bangladesh's military and diplomatic corps.
