Explanation:
Aryan is a designation originally meaning “civilized”, “noble”, or “free” without reference to any ethnicity. It was first applied as a self-identifying term by a migratory group of people from Central Asia later known as Indo-Iranians (who settled on the Iranian Plateau) and, later, applied to Indo-Aryans (who traveled south to settle northern India). The word had no widespread ethnic connotation prior to the 19th century CE other than its usage by the Persians (known as 'Iranians' from 'Aryans') to distinguish themselves from their Muslim Arab conquerors in the 7th century CE, and even then (it could be argued) it was not so much an ethnic distinction as one of class and personhood. Prior to the conquest, Persia had been “the land of the Aryans” and, afterwards, a term was coined for non-Aryans.
'Aryan' became associated with ethnicity and, especially, with light-skinned (Caucasian) superiority, only after Western European scholars began translating, and often misinterpreting, Sanskrit texts in the 18th and more extensively in the 19th centuries CE. Theories had been advanced earlier regarding a correlation between Sanskrit and European languages, but this concept was popularized by the Anglo-Welsh philologist Sir William Jones (l. 1746-1794 CE) in 1786 CE who claimed there was a common source for these languages which he called Proto-Indo-European.
Jones’ claim inspired later writers to identify this “common source” and encouraged the French elitist Joseph Arthur de Gobineau (l. 1816-1882 CE) to develop the racist theories concerning “Aryan Blood” and White Supremacy which would become popularized in Germany through the works of Houston Stewart Chamberlain (l. 1855-1927 CE), the British-born political philosopher who would become Adolf Hitler’s mentor and inspiration as well as informing the ideology and work of Alfred Rosenberg (l. 1893-1946 CE) which empowered the Nazi Party in Germany c. 1930-1945 CE.
