The word arya was used for people who cultivated the mind and character. The aryans were the inhabitants of Aryavrata(India) and they followed Sanatan Dharma for many lakh years in the past, who spoke Sanskrit and practiced Sanatan culture along the banks of the rivers Saraswati and Sindhu.
However racial and cultural stereotypes were not abandoned. The Aryans were supposed to have brought fresh vigorous blood, energy, and ideas to the old, conservative, hidebound civilization that prevailed in India. We repeatedly see images of the conquerors and conquered in the world history texts.
