Cachar district
Cachar district is an administrative district in the state of Assam in India. After independence, the pre-existing undivided Cachar district was split into four districts: Dima Hasao (formerly North Cachar Hills), Hailakandi, Karimganj, and the current Cachar district. Silchar is Cachar district's center of government. Etymology
The term Cachar is derived from the Kacharis people of the Kachari kingdom. The Kacharis were perhaps the earliest inhabitants of the Brahmaputra Valley and Barak Valley of India. The Kacharis call themselves Barman in Barak Valley and Dimasa in the Dima Hasao district. They were known to the Ahoms as Timisa, a corruption of the word Dimasa. They are identical to the people called Mech in Goalpara and North Bengal. History

Pre-independence period
Around 1536, the Dimasa Kachari's elder prince, Drikpati, and a younger prince, Dakhin, had a conflict. Dakhin and his followers were driven out and built a new capital at the Barak Valley, declaring themselves as Dibrasa or the Children of the Barak River (Di means "River", and Brasa means "Barak"). The Dibrasa were later known as Twiprasa and formed the Twipra Kingdom in the Barak Valley. In 1562, the Koch dynasty King Chilarai invaded and captured the Barak Valley from the Twipra Kingdom. King Chilarai gave his brother, Kamal Narayan, authority over the region. The descendants of Kamal Narayan ruled the region until the 18th century. After the fall of the Koch kingdom due to no heir, the Dimasa Kingdom took over and ruled most of the undivided Cachar district. Raja Shri Krishna Chandra Dwaja Narayan Hasnu Kacharihe was the most powerful king of the Dimasa Kingdom  at Khaspur. During Krishna Chandra's rule, the Manipuri king sought help against the Burmese army. Krishna Chandra defeated the Burmese in battle and was offered the Manipuri Princess Induprabha in thanks. Because Krishna Chandra was already married to Rani Chandraprabha, he asked Princess Induprabha to marry his younger brother, Govinda Chandra Hasnu. During this period, Khaspur was the capital of Cachar. The last king of Cachar was Raja Govindra Chandra Dwaja Narayana Hasnu. British period 
The British moved into Assam in 1824 during the First Anglo-Burmese War, helping to prevent the Burman invasion of the area. Cachar was one of the native kingdoms that fell under the imperialist designs of the British. At the time, the Kingdom of Cachar was ruled by two leaders who had clearly defined areas of control—Raja Govindra Chandra Dwaja Narayana Hasnu ruled the plains in the southern portion of Cachar and Raja Tularam Thaosen ruled the hilly northern portion of Cachar or Dima Hasao. Raja Govinda Chandra was assassinated on April 24, 1840, at Haritikar. Because he died without a natural heir, his territories were annexed by the Britsh under the authority of an 1826 treaty; this officially established the modern Cachar district.. The British sent army officer T. Fisher to oversee the region; he established its headquarters at Cherrapunji on June 30, 1830. Fisher was both magistrate and collector, later becoming the first Superintendent of the District. The British annexed Plian into Cachar district on August 14, 1832. The district's headquarters moved to Dudpatil in 1833, and later to its current location of Silchar. Northern Cachar remained a separate principality but came under British occupation in 1854 after the death of Tularam; the British justified this takeover of northern Cachar because of the "misconduct of its rulers." Cachar district fell under the authority of the Chief Commissionership of Assam on February 6, 1874. In the later 19th century, southern Cachar was raided numerous times by the Lushais. Partition 
After India's partition from Great Britain in 1947, the Karimganj sub-division of Sylthet District became part of the Cachar district. North Cachar was separated from Cachar as Dima Hasao district in 1963, followed by  Karimganj district. Hailakandi disrict was formed from Cachar district in 1989. Geography
