Coimbatore District is one of the districts of the state of Tamil Nadu in India. It is located in the western part of the state in the Kongu Nadu region. Coimbatore is known as the "Manchester of South India"[2][3] and is one of the industrialized towns of Tamil Nadu. The region is bounded by Palghat district of Kerala on the west and by Idukki district of Kerala in the South. Coimbatore shares its borders with Tirupur in the East and Nilgiris in the North. A small portion of Erode district shares the border near Puliampatti in the North East. The headquarters of the district is Coimbatore city. As of 2011, Coimbatore district had a population of 3,458,045 with a sex-ratio of 1,000 females for every 1,000 males.


The district was ruled successively by several dynasties of South India. One part of Chera Dynasty, it is speculated that the present-day Coimbatore came into existence as a jungle village under an Irula chieftain under Cholas during the 11th century. The region was part of Vijayanagara empire from 1300's, later by Nayaks of Madurai until 18th century, occupied by Kingdom of Mysore in 18th century from the Madurai rulers. After the Mysore wars in 1792, the district came under control of the British until the Indian independence in 1947.

Establishment of District

Under the control of British, in 1805 a new district was carved out barring a few Zamindaris like Puravipalayam, Samathur, Palayamkottai who were erstwhile Polygars under Nayaks of Madurai. The total area the present covered Nilgiris, Erode, Tirrupur and parts of Karur district and Kollegal taluk in Karnataka. Nilgiri District was segregated in 1868 and Avinashi taluk was formed when Karur was separated from the district and merged with Trichinopoly District. Between 1927 and 1929 several readjustments were made.

Post Independence

In 1956 the Kollegal taluk till then part of Madras State was transferred to Mysore State. Between 1975 and 1979 some subtaluks were promoted to taluks, including Satyamangalam, Perundurai and Mettupalayam, Coimbatore, and the Coimbatore district ended up with 12 taluks. In 1979 Erode district was formed after bifurication of six taluks of Bhavani, Gopichettipalaiyam, Satyamangalam, Erode, Perundurai and Dharapuram.The remaining six taluks would later become nine after two new ones were established and a further new district Tirupur was bifurcated and formed in 2012.[4]
