Chandola is a North Indian Garhwali & Kumaoni Brahmin surname of the Nagwanshi clan and mostly used in the Indian state of Uttarakhand. Chandolas are mainly found in the North Indian Region of Garhwal India (E.G Pauri Garhwal), Kumaon Region & Dehradun. They are considered as the one of the highest castes of the Hindu Religion and are known to be one of the purest races of Aryans. Chandolas now are found in various parts of the world, however still mainly in Garhwal Region of Uttrakhand and Dehradun. While their origins are largely unknown, some link the origins of the Chandola clan to Central India, due to the famous Chandola Lake in Ahmedabad and the Chandela dynasty.
Having been related to the royal family in India, Chandolas now mainly dominate the Government Organizations.
