 In the latter part of the 19th century, it was thought that language, culture and race were inter-related, and the notion of biological race came to the forefront The presumed "Aryan race" which originated the Indo-European languages was prominent among such races, and was deduced to be further subdivided into "European Aryans" and "Asian Aryans," each with their own homelands.Max Mueller, who translated the Rigveda during 1849–1874, postulated an original homeland for all Aryans in central Asia, from which a northern branch migrated to Europe and a southern branch to India and Iran.The Aryans were presumed to be fair-complexioned Indo-European speakers who conquered the dark-skinned "dasas" of India.
