To begin with, Coimbatore was in two parts for purposes of revenue administration. In 1804, the areas were merged into one and brought under one District Collector.During that time, Mr.H.S.GREAME,[I/C] from 20/10/1803 to 20/01/1805 was the Collector, Coimbatore District. In 1868, the Nilgiris District was bifurcated from the Coimbatore District. At the opening of the present century there were ten taluks in the district viz., Bhavani, Coimbatore, Dharapuram, Erode, Karur, Kollegal, Palladam, Pollachi, Satyamangalam and Udumalaipettai.

Originally Coimbatore district formed part of the Kongu country, the history of which dates back to the Sangam age. It is found that in early days the area was inhabited by tribes, the most predominant among them being the Kosars who are reported to have had their headquarters at Kosampathur which probably later became the present Coimbatore. However, tribal predominance did not last long as they were over-run by the Rashtra Kutas. From Rashtrakutas the region fell into the hands of the Cholas who were in prominence at the time of Raja Raja Chola. On the decline of Cholas the Kongu territory was occupied by the Chalukyas and then by the Pandyas and the cysalas. Due to internal strife in the Pandyan kingdom the Muslim rulers from Delhi happened to interfere. Thus the area fell into the hands of Madurai Sultanate from whom the Vijayanagar rulers wrestled for the region during 1377-78 after overthrowing the Madurai Sultanate. For a few years the area remained under independent control of Madurai Nayaks.

During the period of Muthu Veerappa Nayak and later during the period of Tirumal Nayak internal strife and intermittent wars ruined the kingdom. As a consequence during the period of Tirumal Nayak, the Kongu region fell into the hands of the Mysore rulers from whom hyder Ali took over the area. However, consequent on the fall of Tippu Sultan of Mysore in 1799, the Kongu region came to be ceded to the East India Company by the Maharaja of Mysore who was restored to power by the East India Company after defeating Tippu Sultan. From then till 1947 when India attained Independence, the region remained under British control who initiated systematic revenue administration in the area.

The Avinashi taluk was formed in the same year when Karur taluk wastransferred to Tiruchirappalli district. In 1927, some villages of Bhavani taluk together with a few villages from Salem district were constituted into Mettur Area but very soon in 1929, this area was transferred to Salem district. Again in the year 1956 considerable area of the district, viz., the whole of Kollegal taluk was transferred to Mysore State as part of the States Re-organisation Scheme.In 1975, Satyamangalam sub-taluk was upgraded as a full fledged taluk. Again in 1979, Perundurai sub-taluk of Erode taluk and Mettuppalaiyam sub-taluk of Avanashi were also upgraded into independent taluks. Thus the total number of taluks in the district came to twelve. This, however, did not last long. In the same year of 1979, six taluks were bifurcated from the district to constitute a new district called Erode District. Under G.O. Ms. No. 1917 Revenue dt. 31-8-1979, Government of Tamil Nadu the following six taluks were bifurcated from the then Coimbatore district to form a new Erode district. Bhavani, Gopichettipalaiyam, Satyamangalam, Erode, Perundurai and Dharapuram taluks went with the new Erode District that time Coimbatore District contains only nine taluks before bifurication of Tiruppur as a seperate newDistrict viz. Coimbatore(South), Coimbatore(North), Mettupalayam, Avanashi, Palladam,Tirupur, Pollachi, Udumalpettai and Valparai. As per G.O.Ms. No. 617, 618 Revenue dt 24.10.2008, Government of Tamil Nadu the four taluks from Coimbatore District (i.e. Tiruppur, Udumalpet, Palladam and Avinashi(Part)) and three taluks from the Erode district (i.e.Dharapuram, Kangeyam and Perundurai (Part)) were bifurcated and formed another new District called Tiruppur District. This bifurcation considerably reduced the size of the Coimbatore District during that time Coimbatore District has only two revenue sub divisions of Coimbatore and Pollachi and contains eight taluks namely Coimbatore(North), Coimbatore(South), Mettupalayam, Annur, Sulur, Kinathukadavu, Pollachi and Valparai.On 12-02-2014 Coimbatore (South) taluk was bifurcated in to three taluks and formed two new separate taluks of Madukkarai and Perur taluks.A new third Revenue Sub Division was formed by bifurcated fom the old Coimbatore Revenue Sub Divison called Coimbatore North Revenue Sub Divison and Coimbatore South Revenue Sub Divison. Now Coimbatore District contatins three Revenue Sub Divisions of Coimbatore (South), Coimbatore (North) and Pollachi Sub Divisions. As per the latest G.O. No. 419,  Dated: 25-10-2018  by the Department of Revenue and Disaster Management a new taluk of Anaimalai was created by bifurcating Pollachi taluk which was one of the biggest taluk in the District and new Anaimalai taluk comes under Pollachi Sub Division. At present in  Coimbatore District contains eleven taluks of Coimbatore (South), Coimbatore (North), Perur, Madukkarai, Annur, Mettupalayam,  Sulur, Pollachi, Kinathukadavu,  Anaimalai and Valparai revenue taulks.
