Karnataka Tamils
The Karnataka Tamils are a social community of Tamil language speakers living in Bangalore, capital city of the Indian state of Karnataka and Mysore, Mandya, Kolar Gold Fields, Chamrajnagar, and other districts of old Mysore Kingdom. According to The Hindu newspaper, Tamil-speaking settlers migrated to Bangalore in four major waves, the first after the 10th century; the second during the Vijayanagara period; and the third, in the 18th century, after the need for government service required by British East India Company who built the train tracks in Bangalore. Lastly now most Tamilians move to Bangalore for work. However some may say both kannadiga and Tamil were there from the first. According to census 1991, people speaking Tamil as mother tongue in Bangalore formed about 21%. There are 2.1 million Tamils living in Karnataka as of 2011 Census report. History 
According to Srinivas, at the end of the tenth century, the Cholas from Tamil Nadu began to penetrate in areas east of Bangalore; it later began to extend its control over parts of present-day Bangalore, such as Domlur on the eastern side of the city. Around 1004, during the reign of Rajendra Chola I, the Cholas defeated the Western Gangas, and captured Bangalore. In the 19th century, Bangalore essentially became a twin city, with the "pētē", whose residents were predominantly Kannadigas, and the "cantonment" created by the British, whose residents were predominantly British and Tamils. Communities

Arcot Mudaliars 
Arcot Mudaliars are one of the early settlers of the Bangalore city after the  British East India company. They were mostly settled in the Cantonment. Major government monuments in Old bangalore including Chinnaswamy stadium,Town hall were once belonged to the Arcot Mudaliar community. Major roads in Old bangalore are named after the stalwarts of the community. Many temples, hospitals and schools including Annasamy Mudaliar general hospital at Old bangalore managed by the Arcot Mudaliar trusts. Hebbar Iyengar 
Hebbar Iyengars were formerly an endogamous group and constitute a part of the Iyengar sub-caste of the Karnataka Brahmins. They are traditionally followers of Ramanuja and Vedanta Desika. They hail primarily from Hassan, Mysore, Tumkur, Bangalore, and surrounding areas in southern Karnataka. The characteristic dialect of the Hebbar Iyengars is called Hebbar Tamil and is a mixture of Iyengar Tamil, Kannada and Sanskrit. The group's primary mother tongue is Hebbar Tamil which is spoken in most Hebbar Iyengar households, though Kannada and English are increasingly taking its place. A peculiar characteristic of Iyengar Tamil (including Hebbar Tamil) is its retention of divine or holy food terminology. For example, Iyengar Tamil makes distinctions between potable ([t̪iːrt̪o]) and non-potable water ([d͡ʒʌlo]), the former considered sacred but both borrowed from Sanskrit. Standard Tamil exhibits only the generic term for 'water'. The Vaishnavite Brahmins of Southern Karnataka use the Tamil surname "Iyengar" and are believed to have migrated during the time of the 11th century Vaishnavite saint Ramanujacharya. Most Iyengars in Karnataka use sub-dialects of Iyengar Tamil. Thigala 
The Thigala or Tigala are a Tamil social group found in Tamil Nadu and Karnataka states of India, and particularly the city of Bangalore. They are likely a sub-caste of the numerous Vanniyar caste. Every year, the Thigalas celebrate a festival called Karaga. The story of the Karaga is also rooted in the Mahabharata. Draupadi is the community deity of the Vanniyakula Kshatriyas. The Thigala in Karnataka speak a mixture of Kannada and Tamil

Thigala and Bangalore Karaga 
Bangalore Karaga is primarily a well-known tradition of Thigala community in southern Karnataka. The Karaga festival is generally led by the men of the community. There is a legend which gives them this privilege. Thigalas believe that in the last part of the Mahabharatha, when the Pandavas were shown a glimpse of hell, one last Asura (Demon) called Tripurasura was still alive. At this time, Draupadi, the Pandava's wife, took the form of Shakthi devi. She created a huge army of soldiers called the Veerakumaras. After defeating the Asura, the soldiers asked Shakthi Devi to stay back with them. Though she had to go back, she promised them that she would come to stay with them every year during the first full moon of the first month of the Hindu calendar Kempe Gowda  built the Bangalore fort and the town in 1537 A D. And moved his capital from Yelahanka to the new Bangalore. . Demographics 
Tamils form 3.46% of the total population of the state. Almost 5 million Tamils live outside Tamil Nadu, inside India. There has been a recorded presence of Tamil-speaking people in Southern Karnataka since the 10th century. Suburbs of the Bangalore Cantonment (Fraser Town, Murphy Town, Shivajinagar,Shantala Nagar,Vasanth Nagar,Wilson Garden,Langford Town,Benson Town,Ulsoor, Austin Town,Sivanacheti Gardens,Richards Town, Cox Town, Richmond Town, Neelasandra and Viveknagar) have a large Tamil population. They trace their ancestry to the large number of Tamil speaking soldiers, suppliers and workers who were brought into the Bangalore Civil and Military Station, by the British Army, after the fall of Tippu Sultan. The Bangalore Cantonment was directly under the administration of the British Madras Presidency till 1949, when it was handed over to the Mysore State. Significant Tamil-speaking populations are also found in areas of Bangalore not part of the Cantonment such as Chamarajpet, Kalasipalya, Srirampura, Malleswaram, Vyalikaval, Hebbal, Vidyaranyapura and Yelahanka as well as the eastern and south-eastern localities of Bangalore which are in proximity to the IT Corridor (Whitefield, Electronics City and the Outer Ring Road) such as Indiranagar, Banaswadi, Koramangala, BTM Layout, HSR Layout, Bannerghatta Road, J. P. Nagar and Marathahalli among others. Many of the Tamilians living within or close to the IT corridor of Bangalore are first-generation immigrants who have migrated from Tamil Nadu to work in the IT industry in the city. Politics
