 The Aryans spoke Sanskrit and spread the Aryan civilization from India to the west.Witzel traces the "indigenous Aryan" idea to the writings of Savarkar and Golwalkar.Golwalkar (1939) denied any immigration of "Aryans" to the subcontinent, stressing that all Hindus have always been "children of the soil", a notion which according to Witzel is reminiscent of the "blood and soil" of contemporary fascism.
