Badaga tribe inhabited in Nilgiris thousands and thousands of years ago even before common era. They where inhabiting in Nilgiris over 8000 B.C.
During Mouriyan period Buddhist Monks entered Nilgiris to spread Buddhism among the Badagas in Nilgiris. In 1116 A.D. a Baduga King called Kalaraja was ruling Nilgiris. A war fought between King Vishnuvarthana of Hoysala and Baduga King KalaRaja. Kalaraj was killed in the war. Nilgiri came under Hoysala. Later Nilgiri came under Vijayanagar empire and later under sultan rule and after the death of Thipu sulthan Nilgiri came under Britishers.
Even before Britishers arrived to Nilgiris a Portuguese Priest called Rev. Jocome Fierier visited Nilgiris in 1602 and informed he found group of tribal people called Badagas.
Todas, Kotas and other Tribes paid tribute to Badagas. Badaga Headmen attended Toda and Kota panchayat and solved their problems.
Badaga tribal people distinguished their living place into four categories called Porangadu seame, Thothanadu semae, Merkunadu seame, Kundae seame. Where nearly 440 Villages come under this four categories. "Badagu" was the contact language between Badagas and other tribal people before Britishers and other community people arrived to nilgiris.
They are an agricultural people. At the census of 1901 they numbered 34,178. 
"Tundu" (a white piece of cloth) forms an integral part of the attire of Badaga women, and it is presented to dignitaries visiting the villages as a gesture of goodwill. Badagas marry within their community, and there are strict rules about which clan may intermarry with which others. They celebrate Mari Habba, Uppu Attuva Habba, etc., and their important festival is Hette Habba.
In the 1930s, H. B. Ari Gowder founded the Nilgiris Cooperative Marketing Society (NCMS) to help raise prices for Badagas farm products. The NCMS was in response to lowland middlemen who would reduce prices by playing off one farmer against another. Ari Gowder was the first Badaga to be elected to the Madras Legislative Council. The first Badaga to become to headmaster and correspondent of the very famous christian school Breeks Memorial Anglo Indian Higher Secondary School is Mr N Raman.He ran the school for over 25 years.
Badagas worship several Hindu deities, including Shiva, but their main deity is Hethai, Ayya. They celebrate Hethai Habba in a grand fashion spread over a month during December–January every year, and the festival is celebrated all over the district.
